– Volume 4, Grigori. 1
Vali Lucifer is the leader of the Vali Team that was previously affiliated with the Khaos Brigade. He is the remaining descendant of the original Lucifer and the possessor of the Vanishing Dragon, Albion; wielding the Sacred Gear Divine Dividing. As such, he is the direct rival of Issei Hyoudou and Ddraig.
Vali is a handsome young man with light silver hair (dark silver in seasons 2-3) and hazel eyes (light blue in seasons 2-3). He is often seen wearing a dark green V-neck shirt with a high-collared black leather jacket over it. He also wears burgundy jeans with a silver chain drooping down over them and black leather chaps with three bands encircling his right calf, and black shoes with black buckles. As with other Devils, Vali has black bat-like wings on his back. However, unlike other Devils, he possesses a total of eight. Vali also bears a great resemblance to his grandfather, Rizevim Livan Lucifer. Vali's height is 168 cm (5 feet 6 inches) and body weight is [60 kg].
While initially appearing to be a cold, arrogant, overconfident and ruthless person, Vali has a calm, noble, and caring side in him as he cares deeply for his comrades. Vali strongly believes in his own strength. Along with the Longinus "Divine Dividing" and his demonic powers, he refuses to use any other weapon besides the two.
He is known to be a prideful young man like his grandfather and a battle maniac, being obsessed in finding strong opponents, and having said that he would gladly welcome death if there was no one strong enough for him to fight. Additionally, Vali does take some pride in being the descendant of the original Lucifer, but not in the same arrogantly fanatic extent as the other Old Satan descendants. This is most likely due to his childhood where his father, whose fanatical pride as Lucifer's grandson, was one of the two factors that led him to abuse his own son due to having greater potential than himself. Unlike the other Old Satan descendants, Vali has absolutely no interest in supporting the world domination ideals of the Original Satans like Shalba, Creuserey, and Katerea.
Vali shows a proper attitude towards beings that deserve respect.
Vali does possess a more vulnerable side, a side that he almost never shows. This side of him comes from the extreme abuse and persecution that Vali suffered at his father's hand. While Vali never says it, Azazel has noted that Vali actually wanted to be raised in a happy family like Issei's, as well as being a normal person with no special lineage. This was shown in Volume 21 when Aži Dahāka pointed out that Vali's deepest desire is a family.
His painful childhood caused by his father and Rizevim also led him to learn and understand compassion, a trait that other descendants of the original Satans did not have. Vali has repeatedly done selfless acts of kindness such as saving Asia from being disintergrated by exposure to the Dimensional Gap as well as helping Rias to stop Issei's life threatening rampage when he went berserk from activating Juggernaut Drive though he openly demonstrated a neutral demeanor when doing so. The greatest sign of his compassion is that Vali cared immensely for his mother who was the only person in his tragic childhood to have shown him kindness, leading him to withstand his father's horrible abuse for the sake of protecting her. Vali's strong resolve to protect his mother also extends to his younger half-siblings. During his death match with Aži Dahāka, the safety and protection of his mother and half siblings became the driving force and determination that spurred Vali to attain victory against the Evil Dragon.
As a child, Vali was persecuted by his father who was afraid of him and viewed him as a monster due to Vali's ownership of a Longinus in addition to his heritage as Lucifer's descendant. This was later revealed to be a suggestion by his grandfather, Rizevim, who told his son to "bully" Vali if he was scared of him. Vali eventually ran away from his parents and was found by Azazel who took and raised him in Grigori where he trained himself with the intention of killing both his father and grandfather to avenge himself for their responsibility in the painful childhood he endured. At some point, the previous "Ouryuu" had been causing trouble for him and Tobio.
He reappears in front of Kuoh Academy in Volume 4, mocking Issei for his weaknesses and his lack of strength. He later participated in the peace treaty between the Three Factions, fending off several magicians before betraying Azazel and revealing his allegiance with the Khaos Brigade. He then fought against Issei. While initially underestimating Issei due to his background, Vali became interested in him after Issei manages to overwhelm him due to Azazel saying that Vali would half the size of girls breasts, despite the fact he was not using his real strength. The battle, however, was ended abruptly by the sudden appearance of Bikou who asked Vali to retreat before he could use Juggernaut Drive.
In Volume 6, Vali and Bikou appeared in front of Issei after he had just finished his usual Devil work, warning Issei to be careful about Diodora Astaroth. Mil-tan then came passing them wearing Gothic-Lolita clothes and cat ears and were stunned as they couldn't sense his presence till he came closer, Vali asked Bikou if he was a Nekomata using Senjutsu, he pondered that he might be a type of Cat-Troll. The two then left with Bikou suggesting they try the rumored Noodle-shop on the way. He reappears along with Bikou and Arthur Pendragon, saving an unconscious Asia Argento from the Dimensional Gap and gave advice to the Occult Research Club on how to release Issei's incomplete Juggernaut Drive, which was something that could stimulate his heart, which Bikou suggests breasts. Irina then arrived with a device that projected Issei singing the Oppai Dragon Song that seemed to calm Issei down. Vali used his Balance Breaker to lower Issei's, allowing Rias to come in close for Issei to pock her breasts which instantly turned him back, Vali then questioned if Rias' breasts were like a control switch for Issei. After Issei woke up, he revealed his true purpose of being in the Underworld, which was to have a look at the True Red Dragon God Emperor, Great Red, as he reveals to Issei that his greatest desire is to defeat Great Red and become the True White Dragon God Emperor. He asked Issei if he wanted to defeat him, he admitted so as well as a few others, Vali also expressed the same objective and promised to fight again one day, Issei extended his fist in agreement to settle it their as he found it troubling if he were to shrink everyone's breasts, Vali simply found him amusing and told him to get stronger before he and his team left.
In Volume 7, Vali and his teammates cooperated with Azazel to help the Gremory group in their battle against Loki and Fenrir. As Vali and Issei has started to get along with each other, Odin joined their discussion asking him which women's body part does he likes. Vali irritably replied that he's no Oppai dragon, but he thinks that the line from their waist to their hip symbolizes the beauty of women, gaining the nickname Ketsuryūkō (Butt Dragon) from Odin, much to Albion's dismay. In the battle against Loki, Vali used his Juggernaut Drive to hold back Fenrir after they were transported by Kuroka to another location alongside Gleipnir, allowing Arthur to use his Excalibur Ruler to subjugate the giant wolf.
In Volume 9, Vali sends Le Fay Pendragon and Gogmagog to Kyoto to "repay" the Hero Faction for their surveillance on the Vali Team. After hearing Le Fay's report, Vali became interested in Issei's new power which differs from the usual Juggernaut Drive after Issei successfully persuaded two of the past possessors, but he claims that it is not his style to persuade the past possessors and that he will dominate them all instead.
In Volume 11, Vali sends Kuroka, Le Fay, and Fenrir to the Hyoudou Residence as Ophis's bodyguards, who at that time was interested to learn more about Issei. When Cao Cao and Georg attacked the Gremory Team, Vali switched places with Fenrir through a magic circle set up by Kuroka and Le Fay. During the battle, Vali, angered by Cao Cao mocking his past, attempted to activate his Juggernaut Drive but was stopped when Georg under Cao Cao's orders used Samael's poison on Vali, greatly weakening him.
In Volume 12, Vali, still suffering from Samael's curse, hid inside the Gremory Palace while receiving treatment from the original Sun Wukong. He later fought against Pluto, revealing his Empireo Juggernaut Overdrive after sealing all of the past possessors' consciousness and halves Pluto into nothingness in one blast. After Issei defeats Cao Cao, Vali came to check on both on them, commenting on the fact that Cao Cao received Samael's curse and asking why the Truth Idea didn't work which after hearing Cao Cao's explanation, laughs at the latter. He tells Cao Cao that the one who will defeat Issei is him. He then promptly leaves the area with his team.
In Volume 14, though never showing up in person, Vali is mentioned several times, investigating extinct monsters, including Evil Dragons, while running into the Khaos Brigade. Near the end of Volume 14, Euclid Lucifuge received a report that Vali and his team were causing trouble and sent Grendel to deal with him.
In Volume 16, while Issei and the Occult Research Club members are being confronted by Crom Cruach, Vali arrived and said that he and Issei need to team up to deal with the strongest Evil Dragon since he doesn't want to expend more energy after fighting with the possessor of Incinerate Anthem and Euclid Lucifuge. Even though he, with his normal Balance Breaker, and Issei, with his Crimson Cardinal Promotion, teamed up, they weren't able to deal considerable damage to Crom Cruach with the latter stopping the fight after accomplishing his task to stall the group for ten minutes. Vali later met his Grandfather, Rizevim Livan Lucifer, and even though his anger for him was overflowing, he didn't attack him knowing that his grandfather possesses the Sacred Gear Canceller. After Rizevim teleported Vali and the Occult Research Club members to the Carmilla's castle town to witness personally the mayhem caused by the mass-produced Evil Dragon, Vali attacked Rizevim but wasn't able to inflict damage on him and was furious after the latter succeeded in escaping with Euclid and Lilith. After returning from Romania, Vali and the rest of the Vali Team participated in the meeting for the formation of D×D and he agreed to be Odin's adopted son.
In Volume 17, Vali and Issei were being trained by First-Gen Sun Wukong within a space below the Gremory territory to learn to properly use and not waste their power. While Issei was sparring with a Shikigami-like thing made from the old man's hair and Youjutsu, Vali was having a mock battle with Sun Wukong who had the upper hand in blocking his attacks.
In Volume 18, Vali came to Issei's house and watched AV videos with Issei on Azazel's suggestion. After watching Vali seriously trying to find ways to turn what he was watching into Dragon power, Issei became disillusioned with his hobby for a short while.
In Volume 19, he and his team appeared at the Hyoudou Residence underground pool where they witnessed Issei and Rias' new combination technique. While enjoying their time there Bikou wanted to ask Vali for a favor now that their past crimes are cleared but he replied that he wanted to spend his time on attacking Rizevim and the Evil Dragons, as well as training his own power and that he should ask for either Kuroka or Le Fay instead. Arthur then expressed his interests to Vali as he heard that members of the Church’s rebels were Holy Sword wielders, Vali further increased his interests by mentioning the possibility of legendary wielders of holy swords may also be arriving. Tobio joined in telling Vali not to cause any trouble for Azazel, Vali simply shrugged and told him that he'd like to have a fight with Tobio to settle the scores from the last time, but he retorted that his fight is with Issei instead of him. Hearing this, Vali laughed loudly, then turned around to leave as Tobio tried to advised him to at least listen to the planned schedule after today.
In Volume 20, Vali managed to locate where Rizevim had hidden Agreas. Right after Rizevim finished his dialogue with Issei, Vali burst into the room and began a brawl with his grandfather, in which he was easily overwhelmed due to the immense gap in strength, in addition to Rizevim's Sacred Gear Canceller. After Issei's parents learned of Issei's secret life as a Devil and continue to accept him, Vali watched on, confused by what he was seeing. After Issei defeated Rizevim, Vali complimented Issei, telling him he greatly admired the fact that Issei fought for his family.
Vali arrived at Rizevim's location shortly after Azi Dahaka and Apophis left, in which he chanted the chant for Empireo Juggernaut Overdrive. While ignoring Rizevim's pathetic attempts to beg for his life, Vali created a sword made purely from magic. Right as Azazel told Rizevim he would have the honor of dying at the hands of the two Heavenly Dragons, Vali disagreed with him, saying that Rizevim had been defeated by a normal family, saying that Issei possessed something he did not. When Rizevim tried to get Lilith to defend him, Vali persuaded Lilith to defect, after which Vali proceeded to mercilessly cut Rizevim's arm off, much to the latter's surprise and agony. Right as he was about to kill Rizevim, Vali stopped, noticing Fafnir's presence. He stood back and watched an injured Fafnir kill Rizevim. He then told the now-dead Rizevim that while Rizevim had soiled the name of Lucifer, Vali would takeover, declaring that he would not become like him.
Vali found the sleeping 666 with Azazel, then was shocked to learn that Rizevim had a fail-safe in play, in which he would use his soul's energy to forcibly breach the final seal on 666. However, the message was cut short, after which Apophis and Azi Dahaka declared war on D×D and taunted Vali, asking whether he would fight or not. Azi Dahaka chimed in, telling Vali to bring Issei along.
In Volume 21, a few days after the unsealing of 666, Vali was positioned in the Northern Europe region in preparation of the next attack of Qlippoth. Prior to the battle, Vali went to peek on his estranged mother, who had her memories of Vali removed from her by his father. Vali vows to protect his mother and his half-siblings. He later faces off against Aži Dahāka in a rematch as Vali initially struggles against the legendary Evil Dragon, trapping Vali in an illusion where he has a normal family. Vali eventually breaks through the illusion and through the help of Ophis, manages to gain the DxD L, fusing his powers into one as Vali continues his battle against Aži Dahāka and eventually overpowering the Evil Dragon. Before disappearing, Aži Dahāka makes a promise with Vali to return and fight again.
Exhausted from his battle with Aži Dahāka, Vali later had to watch his mentor and father figure Azazel, leave as Azazel, along with the other leaders sacrifice themselves by taking 666 into the Isolation Barrier Field, much to Vali's dismay as he was unable to voice out his plea towards Azazel. Vali was later confined to a hospital room with Issei to recover with Ophis and Lilith for company. When Issei wakes up, Vali tells him how Ophis adjusted the power borrowed from her thus curing him of his Dragon Deficiency. Vali also tells Issei how Azazel and the others Mythology leaders are gone, he notes with a trembling voice that they both have bodies able to survive a very long time and will await Azazel's return to complain to him.
In Volume 22, Vali and his team go fishing with the Occult Research Club and Issei's parents, with Vali tagging along with Issei to find a fishing spot. Vali tells Issei that he's been promoted into Ultimate-class, an offer he originally turned down, but accepted once he was told that his promotion was Azazel's wish. Vali then tells Issei he's going to participate in the Azazel Cup, which he finds the perfect opportunity to fight God-class beings without causing trouble to anyone.
Red Dragon Emperor of the Blazing Truth × White Dragon Emperor of the Morning Star: The True Dragon(s) of the Kuoh Academy
Vali then participates in the opening ceremony and was pleased of Issei's arrival, in which he bumps fists with him. Issei tells Vali let's have a good battle as Heavenly Dragons.
In Volume 23, Vali and Saji were both invited by Issei to go fishing. While on their fishing trip, Issei revealed the purpose of it was to ask them that he wanted to know what reason he should have for himself to enjoy a simple battle without life or death consequences. The three are then paid a visit by Vali's adopted brothers; Vidar and Apollon, who informed them that they both became the leaders of their respected mythologies and are teammates under Typhon's leadership in the tournament. All of a sudden, their communication devices rang and they received news of Rias' match, the three dragon wielders then transported over to see it for themselves.
In Volume 24, Vali and his team faced off in their next match against Rias and her peerage at the Fafnir Stadium under the Board Collapse rules, where the field will begin to collapse starting from both ends. Right before the game would commence, Vali went to get a drink from a vending machine when to his surprise came across Lavinia who selected the drink for him knowing it was the one he takes before an important battle. She let him know that she would cheer for him but Vali paid no mind to it. When he had almost arrived back to the waiting room, Albion laughed lightly as he asked Vali does it feel to have his princess cheer for him, Vali continued to act as if none of his concern.
After the game had already started, Vali arrived wearing his Empireo Juggernaut Overdrive armor with Fenrir by his side to Gogmagog, Bikou and Arthurs location where they were having difficulty dealing with Vasco Strada. He asked the Church warrior what did Rias promise him to participate in her team, which Vasco demonstrated by taking a concoction that reverted him back to his fifties which he claimed to be his prime. Vali and his friends were easily overpowered by Vasco by what seemed to be with little ease, being able to cut through Vali's energy attack and even damaging his armor. Vali continued to fire off blasts of demonic energy from close range but Vasco evaded all of them with minimal movement. Vali then accelerated his speed to the point of seemingly vanishing to strike at him from behind, however Vasco predicted his moves and appeared even faster behind Vali instead. Vali was able to immediately move away from Vasco's counterattack, even the wave of holy aura from his sword that followed after reached him at high speeds was evaded. Vasco's next attack was his bare fist that had broken through Vali's armor and directly hit his abdomen, causing him to retreat backwards. Vasco unleashed another wave of holy aura while Vali could only block it with his crossed arm, the aftermath showed that Vasco's attack had completely shattered his armor. Arthur then stepped in wanting to take on Vasco himself and advised Vali to take Fenrir to Rias' and Crom Cruach's location, he recreated his Emperio armor and did so after being further urged by Bikou.
Vali flew to Rias' current location while carrying Fenrir and let him fight with her while he personally went up against the Evil Dragon; Crom Cruach. Crom made the first move as he charged straight at Vali with his right arm morphed into a dragon’s large claw coated in an unbelievably dense aura, Vali dodged with the smallest possible margin, the two engaged in a fierce melee battle in mid-air, exchanged blows at high speed with each blow generating immense vibrations and booms in the air that caused the entire atmosphere to tremble. Vali primarily focused on evading his attacks which Crom mocked him for, though Vali retorted by saying that he wanted to see all of the so-called strongest Evil Dragon attacks first as an appetizer. Crom then pulled back temporarily to express how proud he was that an evil Dragon like him could fight against a silvery-white dragon like Vali and that he had no regrets over it.
Their fight continued with Vali firing a bombardment of Demonic Energy this time but was repelled by Crom's fist, who deflected them towards the surrounding buildings. Crom Cruach then spewed forth flames which covered the entire sky, Vali attempted to counter them with his Compression Divider but proved unaffected as he was hit by the flames, Crom then dived into the scorching fires to continue to assault Vali amidst the inferno of searing flames. Vali used his silvery-white aura to blow away the flames but was still met with a melee assault from Crom Cruach, his armor had been melting from the flames and also cracked from the Evil Dragon's blows so he struck a blow of energy at Crom to momentarily retreat but the Dragon gripped onto him and transformed his other arm into a large Dragon's claw and thrust it straight across, Vali was forced to endure the attack with no means of escaping it which caused him to be propelled backwards through various skyscrapers. Despite being worn out gasping for air, Vali still flew immediately out of a collapsed building and came back to stand before Crom’s eyes, he also expressed how honored he felt to fight him before activating his DxD armor. Vali moved at an abnormal speed beyond perception but still received a hit from Crom Cruach's fist, he then immediately recomposed himself and moved at his incredible speed once again, only this time he unleashed attacks of his Lucifer aura that finally made Crom bleed. Even so, Crom was still able to deliver a punch towards Vali that sent him souring down and shattering the armor around at his abdomen, causing him to also spit out blood. Crom continued to pursue him. All Vali could do was gather aura to his arms to block, he asked the Evil Dragon how was he able to hit, to he simply replied Intuition.
Vali then asked Albion how he'd measure the difference between himself and Crom, the White Dragon answered that Vali had the upper hand in terms of skill, technique and speed but Crom Cruach was better in overall destructive power, Vali laughed out wildly as an opponent who could defeat him had appeared before his eyes. Crom then spewed out flames much fiercer then before, this time however Vali used his Satan Compression Divider that completely erased the flames, he then sent his Wyvern Fairies towards Crom to continuously use his Half Dimension on him which restricted his movements while attempting to advance forward but to Vali's surprise was able to break though and destroy the wyverns one after the other. Vali continuously bombarded him with his absolute aura, but Crom continued to fly straight towards him without signs of dodging as a massive explosion went off upon contact, Crom emerged from the smoke to thrust another punch at him and let loose a mouthful of flames as well. With clear resolution, Vali unleashed a blast of demonic energy directly at Crom’s abdomen causing another explosion, he then flew back augmenting their distance. Crom Cruach’s body was covered and dripping in blood but his fighting spirit hadn’t decreased at all, rather he had become even more motivated which made Vali laugh, they both made an oath to each other to continue fighting until the very end.
Although their fight had ended due to Rias' situation that forced her to surrender, leaving Vali and his team the winners. Both Vali and Crom were completely battered and upset that their battle had come to an abrupt end. Vali approached Crom and extended his hand out for a handshake, Crom smiled as he brushed Vali’s hand aside and flew over to Rias, Vali looked at his rejected handshake attempt and cheerfully laughed by himself. A few days had passed since the battle between him and the Gremory team, Vali and Issei felt a wave of inexplicable pressure from when meeting with Verrine and Balberith whom they claimed to be Super Devils, a statement that shocked everyone present. They soon left hoping to meet the Heavenly Dragons in a match. Not only Vali and Issei but also their Dragons were baffled by their existence.
In Volume 25, Vali and his team celebrated at the Hyoudou Residence along with their rival teams. Vali converses with Issei of how he aims to be the winner while Issei agrees but must face each other in a match as Heavenly Dragons.
Vali reappeared in the end of True Volume 1, appearing at the Agares territory with his team for the tournament to announce the next upcoming matches and reminded Issei not to lose until he faces him in the match.
In True Volume 2, Vali moved to Kuoh Town under the recommendation of Vidar and his own team members, with the help of Lavinia and Natsume. Vali became surprised to see Issei at his new apartment and was annoyed by Natsume as he told her that he can move things on his own and didn’t expect her to request from Issei, she playfully tapped his head as she told him that he should accept help from his destined rival. Vali became interested of hearing about Tobio arriving at his apartment to make noodles and Natsume started to talk about his past of loving noodles with Issei, much to his embarrassment. Vali and Issei started to converse about Ingvild when he took interest in their similarities and asked Issei if he plans to use her for the tournament, which he is unclear of. Vali asked Issei if he plans to hold back against Rias, which he clarified he doesn’t plan to lose, and Issei tells Vali not to lose against Sun Wukong. After he was finished unpacking, Vali gave Ingvild a white dragon plushie as gratitude for her help on her devil work.
Powers & Abilities
Immense Demonic Power: Being a descendant of the Original Satan, Lucifer, Vali has an impressive amount of demonic power. During the interrupted conference between the Three Factions, he stated that with his demonic power inherited from the original Lucifer and the power of Albion through Divine Dividing, he could be one of the strongest beings there is. This was somewhat proven when Azazel declared him as The Strongest White Dragon Emperor of all known history, past, present and future due to his unique heritage. His high demonic power helped him in controlling his Juggernaut Drive as he used it as an alternate source of energy instead of his life before gaining his Empireo Juggernaut Overdrive. In fact, the amount of Vali's demonic power is so large that he was able to stay alive and endure after getting hit by Samael's curse (though Sun Wukong had to save his life). He can also control his demonic power after he shoots it out. When combined with his Diabolos Dragon Lucifer armor, Vali's demonic power is drastically strengthened to the point that he can completely destroy a 5,000 meter-tall mountain in one attack. Vali has become a candidate for becoming a new Super Devil.
Master Hand to Hand Combatant: Trained by Azazel, Vali is a extremely proficient combatant, he is able to easily defeat Kokabiel, a Fallen Angel Cadre without using his full strength. In Volume 4, he easily overwhelmed Issei in his incomplete Balance Breaker Armor even with the latter using Ascalon. After training with Sun Wukong, Vali further improves his combat skills, being able to beat Aži Dahāka on his own, an enemy Vali previously fought against with his entire team and failed to defeat. When combined with his Diabolos Dragon Lucifer armor, Vali's skills allow him to fight on par with Crom Cruach.
Magic Talent: Vali has also shown to be extremely talented in using magic, capable of learning Norse Magic in a very short period of time and was able to immediately use it during his fight with Loki. He is capable of using teleportation magic, as well as defensive magic to protect himself and others from powerful attacks.
Immense Durability: Vali has an extreme tolerance to pain. This is seen where he has no problem enduring vicious wounds during his fights with Fenrir in Volume 7 and also to Cao Cao in Volume 12. Even after being viciously bitten by Aži Dahaka in a heavily exhausted state, he can still muster enough strength to use the Satan Lucifer Smasher. In Volume 24, Vali was durable enough to take punches from a Vasco in his physical prime. In the same fight, he was also able to endure vicious attacks from Crom Cruach.
Immense Speed: Vali is noted to be extremely fast. He was able to rip off Kokabiel's wings before Kokabiel could even react. During his fight with Kokabiel, Yuuto commented that Vali could move at the speed of light while using his Balance Breaker. While fighting against Loki, Vali was able to fly in a acrobatic-style, dodging Loki's attacks with ease with Loki himself acknowledging Vali's speed. During his fight against Prime Vasco Strada, Vali in his Empireo Juggernaut Overdrive was able to circle around him with nearly god-like speed to the point where his figure vanished from sight and while fighting against Crom Cruach, he was able to dodge Crom's attacks with relative ease. In his Diabolos Dragon Lucifer armor, he is able to move at godspeed that was beyond perception. Crom Cruach wasn't able to catch up with him or even perceive him, only managing to hit Vali due to his vast combat experience and battle intuition.
Immense Stamina: Vali possesses a great amount of stamina, being capable of maintaining his Balance Breaker for at least one month. In Volume 24, he was able to keep fighting even after being injured by Vasco, and then against Crom Cruach, the strongest Evil Dragon.
Flight: Being a half-Devil, Vali can fly using his 8 wings.
Divine Dividing (白龍皇の光翼, Dibain Dibaidingu): Vali's Sacred Gear and main and only weapon. The Divine Dividing is one of the 13 Longinus which holds the spirit of the Vanishing Dragon, the White Dragon Emperor, Albion, one of the Heavenly Dragons. Divine Dividing takes the form of a pair of wings on the users back that enables flight that can reach up to light-speed. These wings works in the opposite way of Issei's Boosted Gear, in which it has the ability to Divide the opponent's power in half after coming into physical contact with them every 10 seconds, the opponent's drained power is then added to himself and when he reaches his maximum limit, the excess power is then released through his wings. Later on, Vali gains the ability to Reflect, allowing him to redirect incoming attacks.
- Divine Dividing: Scale Mail (白龍皇の鎧, Dibain Dibaidingu: Sukeiru Meiru): Divine Dividing's Balance Breaker that creates a White Dragon Armor similar to Boosted Gear Scale Mail. In this form Vali is able to use Divide without the 10 second limit. The Divine Dividing also has the ability to halve the size of objects and living beings through the use of it's Half Dimension, the user does not need to make any contact with the target to use this ability.
- Juggernaut Drive (覇龍, Jagānōto Doraivu): A form unique to the Boosted Gear and Divine Dividing. The Juggernaut Drive temporarily removes the seal placed on the Heavenly Dragons granting the user immense power. The Juggernaut Drive, however, causes the user to lose sanity while having their lives devoured by the power. However, Vali is able to avoid this using his large amount of demonic powers as an alternative source of power instead of his lifespan; however, if used for extended periods of time, it will eventually cause him to go berserk. Even after deactivation, Vali suffered from immense exhaustion.
- Empireo Juggernaut Overdrive (白銀の極覇龍, Enpireo Jagānōto Ōbādoraibu): A new enhanced form that surpasses Juggernaut Drive. Vali obtained it after he successfully sealed all of the past possessors' consciousness. In this form, the color of his armor changes to silver. Like Issei's Cardinal Crimson Promotion, it does not consume his lifespan. When first introduced, Vali can only sustain this form for a short period of time before he must deactivate. By Volume 24, however, he is able to maintain this form for a much longer time.
- Compression Divider: In this state, Vali can use an enhanced version of Half Dimension, which halves a specific target constantly until they vanish from existence. However, as stated by Sun Wukong, currently Vali can't maintain this form for very long. This ability is very powerful as it killed Pluto in just a second.
- Diabolos Dragon Lucifer (魔王化－『D×D』・L－, Diaborosu Doragon Rushifā): Vali's DxD form. This form is the combination of the White Dragon Emperor's power and the Lucifer power that Vali synced through Ophis' blessing. Similarly to the Diabolos Dragon God Issei possesses, the armor is a mix of silvery-white and jet-black, and also possesses the same organic characteristic. Vali gains twelve wings of Lucifer in this form, which can be ejected and turned into wyverns, similarly to the Dividing Wyvern Faeries that Issei is able to create. The power that Diabolos Dragon Lucifer possesses is enough to completely destroy a 5,000 meter-tall mountain in one attack and fight on par with Crom Cruach, the strongest Evil Dragon. Vali can only sustain this form for a short time.
- Satan Compression Divider: Vali builds up his power and releases an ultimate blast of silvery-white and black demonic radiance that halves anything within its range until it vanishes from existence. Azi Dahaka notes that this is not an ability or a technique, but a simple release of light.
- Satan Lucifer Smasher: Vali's own enhanced version of Longinus Smasher. Similarly to the Longinus Smasher, a cannon muzzle appears from the chest cavity which then fires a bombardment of silvery-white and black aura.
- Dividing Wyvern Fairies: In this form, Vali can detach his wings which then form into small white Wyverns that can also use Divide and Reflect, as well as using Half Dimension. The Wyverns are able to change into cannons that fires out a powerful shot of Lucifer’s aura. The Wyverns are also able to use Albion's hidden technique Reduce, an ability that releases a deadly venom which could kill anyone as it cuts down not only their bodies but also their souls, however, this is ineffective towards Ophis, Great Red and Ddraig.
Crimson Gourd: One of the Five Treasured Tools of Taishang Laojun (The Grand Supreme Elderly Lord). It has the ability to suck in and imprisoned those who responds when they have their name called out. Vali borrowed it from the Golden Horned King and the Silver Horned King, so he can use it as a punishment for Bikou and Kuroka where they can reflect on their mistakes.
- "I just want to fight eternally." (Volume 4, Life 5)
- "I’m a descendant of the previous generation’s Maou Lucifer who died. However, I’m a child of mixed blood born from a father who was the old Maou’s grandson and a human mother. —I obtained the [Vanishing Dragon]’s Sacred Gear because I’m half-human. It was just by chance. However, I, who is a true blood relative of Lucifer and is also the [Vanishing Dragon], was born. If there really is such a thing as fate and miracles, I may be that. —Just joking." (Volume 4, Life 5)
