Rei

""Kyaa.""

Shark Girl is the Class S Rank 11 professional hero of the Hero Association.

Rei is socially awkward and doesn't know how to act in most normal situations. She's often known for her horrific stare and shark teeth; although she seems to be glaring at people, Rei's actually just nervous around others. But beneath her appearance lies an adorable personality. Rei also has an involuntary compulsion to harm anyone that poses even a bit of a threat to her or her friends. In or outside of missions, anyone who is seen harming a civilian or ally will enrage Rei.

She is perfectly capable of hearing, reading, and comprehending even complicated and nuanced concepts in spoken English, although she communicates through small gestures. Though Rei is capable of vocalization, she is physically incapable of complex vocalizations to produce understandable speech, keeping her in a muted state.

Powers

 * Shark Physiology - Rei is capable of swimming at high speeds underwater, even in extremely deep waters. Such makes her a blur to any present onlookers, usually creating shockwaves from the point of departure. Her body can withstand several blows without losing momentum, all while creating powerful attacks. On land, she can still run inhumanly fast and strike hard, but these stats are increased when submerged in water. She is also capable of instantaneous regeneration when exposed to enough water.
 * Brute Strength - Rei's melee attacks are undeniably powerful. Her fighting style revolves around the use of powerful kicks and dangerously sharp claws. Given enough force, a single strike is capable of blasting off parts of the target. Rei's strength lets her hold her own against several opponents.
 * Hypersonic Waves - The power to release strong sonic waves from her body, capable of both damaging and paralyzing Rei's targets. These waves act as constant white, black, and cyan-colored ripples, which overwhelm the enemy's senses and keeps them from moving their body. However, the effectiveness of the hypersonic waves decrease with range, so Rei must paralyze those within close proximity to her.
 * Echolocation - By using her sonic waves as a medium, Rei can detect living creatures or objects in places they may be hidden. This skill is imperfect, though, but it provides a way for Rei to sense what's around her.
 * Camouflage - Albeit its name, this is not real camouflage. Rei uses her sonic waves to temporarily distort the brains, and subsequently the vision, of everyone around her, making it seem that Rei had left the visible spectrum without harming those affected. This only works on living targets and not on machines nor cameras.

Weaknesses

 * Extreme Heat - Her aquatic body makes Rei weak to high temperatures and even more to dehydration, hindering her overall performance. This can only be countered when re-hydrated, even if it's just a bottle of water.
 * Big Eater - Rei is easily distracted by food, making her prone to attacks when her head is not in the game. She eats a lot during the day, capable of ingesting virtually anything that's labelled to be food. That also includes human body parts.

Equipment

 * Razor Sharpness - Along with her predator combat style and shark-like body, Rei's claws and teeth are known to be incredibly sharp, capable of tearing flesh, shattering bones, or reducing large machinery to pieces. This acts as Rei's main form of finishing fights, rendering her to be highly dangerous at close quarters.
