Sun Wukong is the first Monkey King and is known as The Great Victorious Fighting Buddha and the Great Sage Equaling Heaven. He is also Bikou's ancestor and Indra's former vanguard.
Sun Wukong has the figure of a primary school child (at least a meter tall), covered in golden fur (Dark beige in the anime) wearing a monk's cassock, a wrinkled, creased face and black skin (Beige in the anime). He is also seen carrying a staff-like weapon, smoking a pipe, wearing shades with a cyber design, and also donning prayer beads on his forehead.
Sun Wukong claims that he is a free geezer, not caring much for worthless things. Despite so, he would carry out the orders given to him by Indra and is shown to be wise enough to give advice to people. Sun Wukong may have a jokester personality as Yuuto Kiba once claimed that he can sense similarities in Sun Wukong's personality to that of Bikou's. In fact, Sun Wukong was known to be extremely mischievous in his youth as he's known to have once playfully caused a havoc so immense, that the Buddha had no choice but to imprison him underneath a mountain. Despite all of this traits, he is very wise and intelligent enough to explain to Yuuto about Samael's deadly poison blood and how a soul is very fragile and weak (if it doesn't have anybody).
He also hates Devils from the Old Satan Faction, claiming that they were the ones responsible for the destruction of his kin in the past. However, Sun Wukong's hate of the Devils is limited to their past generation as he believes that the current generation of the Devils is different and so, cannot be held responsible. He understands the value of determination and commitment and isn't hesitant to acknowledge others as shown when he complements Issei for defeating the Hero Faction and protecting his comrades even without the use of the Juggernaut Drive. Amongst the very few Gods, the few that he respects are Sakra, the Trimurti gods, Odin, Zeus, and the God of the Bible, as he generally hates evil beings, or Gods, that desire nothing but to conquer, destroy, or bring chaos to the world. He also has great respect towards the current leaders of the "Three Great Main Powers", and believes that they are strong and are capable of managing their own Factions very well.
Sun Wukong is a monkey that was born from a stone and acquired supernatural powers through Taoist practices. After rebelling against Heaven, he was imprisoned under a mountain by the Buddha. Before that had happened, he had earlier fought against the Bull Demon King, the one who manipulated him into rebelling against Heaven by killing his friends. After a massive battle, he successfully banished the Bull Demon King from Heaven after the latter attempted to overthrown and rule it. He later accompanies the monk Xuanzang Sanzang on a journey to retrieve Buddhist sutras from India while being accompanied by "Pigsy" (猪八戒 Zhu Bajie) and "Sandy" (沙悟浄 Sha Wujing), both of whom had offered to accompany the priest in order to atone for their previous crimes. The group encountered a series of eighty-one tribulations before accomplishing their mission and returning safely to China. There, Sun Wukong was granted Buddhahood for his service and strength.
After his ascension to Buddhahood, Sun Wukong eventually became Indra's vanguard. Shortly after the Khaos Brigade became known to the world, Sun Wukong was sent by Indra to fend off the organization and succeeded in fending off many terrorist attacks, especially the ones led by the Old Satan Faction and the Hero Faction.
At some point in the past, he met a young Cao Cao. Cao Cao learns from Sun Wukong about how he carries the blood of the hero Cao Cao which was something that he and his parents weren’t aware of. Since then he and Indra made contact of him before Cao Cao joined the Khaos Brigade but still keeps an eye on him, as Indra's orders.
He makes his full appearance alongside Yu-Long at Kyoto in Volume 9, helping Issei and his friends during their fight against Cao Cao and the Hero Faction, who were mind-controlling Yasaka. As soon as he appeared, he effortlessly overwhelmed the Hero Faction, by defeating Siegfried in one shot, destroying the mist of Dimension Lost and blocking Cao Cao's True Longinus with a finger, all while claiming that they are still too young to challenge him, and forced the Hero Faction to retreat. He later advised Issei to use Pailingual on Yasaka to test if he can help her regain her consciousness, which it does. He then has a chat with Issei apologizing to him for the trouble caused by his kin and complimented the boy for choosing a different approach to harness the power of the Heavenly Dragon, instead of the usual Juggernaut Drive.
He was looking for Bikou until the latter calls him in Volume 12 to ask for his help in healing Vali Lucifer who is cursed with Samael's poison. Yuuto also asks him about Samael's poison in hopes of getting a hint on Issei's chances of survival to which Sun Wukong answers that the density of Samael's curse is very powerful, so there's a high chance of Issei's soul perishing alongside his physical body, since according to him, there is nothing more fragile than a soul that has lost its vessel. He then asks if Samael's curse was detected from Issei's Evil Pieces to which Yuuto confirms that there was none. Hearing this, Sun Wukong theorizes that despite the lack of his physical body, Issei's soul might be safe. He also gives assurance to Yuuto and the Vali Team that Indra won't rampage like Hades, before leaving the Gremory territory with Yu-Long to deal with the Khaos Brigade.
In Volume 16, Sun Wukong participated in the meeting for the formation of the D×D and was appointed as the sub-leader. He also proposed in training the members of D×D where they will be able to reach Ultimate-class strength and for the Longinus possessors to fight on par with God-class opponents.
In Volume 17, Sun Wukong helped train Issei and Vali to effectively use and not waste their powers. He, personally, sparred with Vali, with Vali not able to hit him at all, while a dummy in his likeness trained Issei to try and use the same amount of power ten times in a row.
In Volume 21, during the war against Qlippoth's army with the imperial beast in their control, Sun Wukong arrives mid-battle riding on Yu-Long along with Zhu Bajie, Sha Wujing, and Nezha, wiping out as many Evil Dragons and fake Scale Mails as they can.

In Volume 22, Sun Wukong participates at the opening ceremony of the Azazel Cup, while also bringing Yu-Long, first generation Zhu Bajie, first generation Sha Wujing, and the Nezha Prince despite having decided to retire them. Sun Wukong noticed Mahabali glaring at Indra, he advised him that it won't be too late when he does fight Indra.
Sun Wukong appeared in Volume 25, to celebrate at the Hyoudou Residence with his team and the rival teams for passing the preliminaries.
Sun Wukong reappeared in True Volume 3, together with Suzaku Himejima at the giant traditional mansion to meet with DxD team to discuss about the Five Principal Clans offering their full support and he wishes to tell them something. He reports to them that the temples that worships Enma have been affected by Olympus magic spells to make him mad and laughs when Issei says they’re sly, he later assured that they will protect Kyoto while doing some sightseeing and tells the group to enjoy the Oppai Dragon show and he will defeat his enemies with his Ruyi Bang. Sun Wukong later summons the Hero Faction members to apologize to Yasaka for the trouble they caused last year and she accepted their apology.
