Little Boy

Little Boy is the code name of Solace Vortigern, an assassin of the Vortigern Clan and a member of the Momerath Family. The youngest son of the family, he has been rendered mad from the Clan's exploitation of his Semblance and extensive amounts of Dust experimentation. A true berserker, he wields the Murasame Original Sever, a massive blade that can cleave gashes into the land around it and wreak havoc through wind pressure alone.

Weapon
Little Boy's primary weapon is his Murasame Original, the Land Buster Sever. It is a titanic 4-meter-tall cleaver with a 1-meter-wide T-shaped blade that looks like it was carved out of igneous rock, with glowing lava veins crisscrossing over its surface and tiny volcano-like holes dotting it. Thick enough that a normal person can fit his whole palm on the blunt edge, it weighs nearly a ton and with Little Boy's strength, has the power to horrifically break the eight-story-tall Great Goliath's body with one swing. Its unique attribute granted by its creator is that whenever it is swung, the volcanic holes across its surface help to collect into the blade and then concentrate said air onto the edge of the blade, releasing it in a hyper-pressurized wave that can slice gashes into the landscape. This makes it a massively powerful weapon at mid-range as well, as practically every slash results in this cutting wind being fired off. While many Hunters have figured out how to release an air-slash through applying their own Aura, Sever still reigns supreme due to its combination of both its requirement for a physically powerful user and its own mechanism being completely bereft of Aura reliance, just sheer strength. Because of the air-flow into the holes, Sever may also seem to hum when it is swung.

Abilities
The foundation of Little Boy's combat potential comes from his Aura, so we will lead with that.

Aura
Little Boy's Aura is especially notable for the fact that it does not form a shield around him. Instead, its entire energy is dedicated to working inside his body. In exchange of this defense, this grants him incredible amounts of strength, speed and a reflex speed of 0.05 seconds, making him both strong and fast.

He should have been a glass cannon if not for his Semblance "Body Enhancement - Evolutionary Regeneration". It grants him incredible amounts of regeneration that allow him to regrow body parts within a blink of an eye, while also providing life force so strong that he can survive long enough as just a head to allow himself to regrow a new body. At the same time, the regenerated body part is altered in such a way that it not gains greater strength, but the previous attack is slowly rendered ineffective from then on. Adaptations that Little Boy has gained so far are: great size and weight to prevent him being tossed around by wind and water, total shutdown of pain, body-wide ceramic-like scales that can withstand high temperatures and pressures, muscle fibers that reflexively harden the moment they detect an invading object like a spear-point or blades, long thick tentacles for hair that help deflect bullets every time he spins and blood filled with thousands of antibody types to counteract all the poisons and diseases he had been given in his life.

Note that while Little Boy's Semblance is extremely powerful on paper, all of his adaptations are purely defensive and are also matter-based and biological in nature, meaning that there are some powers that will almost always be able to affect him, such as Vulturn's space-shifting Bypass or Glynda's telekinesis. The only offensive power Little Boy gains from his Semblance is his infinitely growing strength, with speed if it is his legs being regrown, and he gains no utility like heightened senses or additional limbs from his power other than the side-effects from his defenses.

Attributes and Fighting Style
Little Boy is the physically strongest fighter on the Vortigern Clan side, matching Art who has his own strength-stacking abilities and Vulcana with his ability to self-modify, and he has speed to boot, even under the weight of all his adaptations. His heightened reaction speed makes him extremely hard to surprise and hit, while also granting him a greater dexterity with his attacks than what his bulk suggests.

Despite his madness, Little Boy has some form of fighting style, namely he is notable for always wielding Sever with both hands in a style akin to kendo and he is perfectly capable of responding to attacks with the necessary parry or counter-strike. However, beyond that, he is well and truly mad, taking blows without a care for the world, charging forth through missile-strikes to get at his assigned target and attacking with lethal ferocity even if his allies are in the way. His Semblance to physically adapt to almost any threat has robbed his mind of any experience with mentally adapting, hence he never learns from his mistakes and will keep tackling obstacles with brute force no matter how inefficient it may be.
