User:Crimson and Darkness/Ex Gremory

Ex Gremory is the son of Issei Gremory Hyoudou and Rias Gremory, the fourth eldest son as well as the sixth eldest sibling, he is known as the God Slayer of the Scarlet Blade.

Appearance
He is described as a young teen with red hair.

Personality
Ex is a typically very obedient and brave lad but is also headstrong as he has a tendency to become reckless when someone important to him is injured and taking more independent action on his own, Airi is so far the only sibling who can scare him into following orders. Ex has conflicting feelings towards his father, for he initially has a slight dislike for him on account of Issei failing to protect Asia from when Future Loki placed her in a coma with his curse, but at the same time misses him very much since he hardly ever spending time with him and admires how he is always able to continue fighting. Compared to his father who is open about his perverted desires, Ex is rather shy in contrast.

Unlike Issei, Ex is merciless to his enemies mostly due to being Vali's student, as he was willing to kill Loki after he cursed Asia. According to what Rias and Issei told Gasper, Ex's demeanor is very much like that of Sirzechs Lucifer.

History
Ex was trained by both Vali and Kiba in both Dragon power and swordsmanship respectively; therefore he is the young ace of the united armies of all combined mythological systems, as well as the strongest swordsman of the Gremory family. He very rarely sees his father who is always busy fending off enemies.

Powers & Abilities
Immense Demonic Power: Due to being Rias's son, Ex has a great amount of demonic power, which surpasses her own in the present day. Ex, along with his older half-sister Airi is considered as a ace of the vanguard of the future allied mythologies alliance. Ex strength is such that the escaped Loki felt fear at facing him in direct combat.

Equipment
Boosted Gear Diabolus: Ex's artificial Longinus. It was designed by his older half brother Kurenai Himejima. It functions in the exact way as his father's Boosted Gear, being able to use Boost to double and enhance his own physical attributes and demonic power. Ex can also use it to enhance the Power of Destruction he releases or when he clads it onto his blade Galatine III. However, despite it having greater power then a normal artificial Sacred Gear, the gauntlet is stated to be inferior in terms of power output compared to the genuine Boosted Gear. However due to it only recently being created and the fact that Ex isn't fully experienced in wielding it, the gauntlet is a bit unstable to use if overworked.
 * Crimson Dragon Sword of Extinction: The Counter Balance of Boosted Gear Diabolus, which forms crimson colored Scale Mail armor, which has four dragon wings on it's back as well his sword Galatine III, which also transforms and changes shapes. Allows Ex to use Boost without the 10-second limit and it strengthens his powers and abilities. Ex also gains a new ability called Boost Blade, which strengthens his sword Galatine III with the power of his Sacred Gear, empowering it further with his dragonic aura and his Power of Destruction.

Scarlet Blade Galatine III Revised: Ex's sword which was forged for his personal use. Due to being a successor to the legendary sword Galatine which was famous for having a blade that would never get nicked, it is quite strong and durable. Due to it's durable nature, Ex can safely envelop the blade with his Power of Destruction.

Trivia

 * Ex's name is an interesting case; the katakana spelling may suggest to a French name, "Ickx" (which is a very uncommon surname, even in its native Belgium), but its actual meaning lies on two aspects: a shortened form of Rias' ultimate technique, Extinguisher Star (イクスティングイッシュ・スター), or an amalgamation of Issei and Sirzechs' diphthong on their names (I for Issei, "kusu" for Sirzechs ( Saazekusu).  The latter aspect, in turn, references the titular character name of Boruto as his name references both his father Naruto and uncle Neji (Boruto is the common kana for "bolt" similar to Neji's name meaning, "screw").
