Name: Katsuo 'Katsu' Isamu
Age: 15
Gender: Male
Height: 5'11
Occupation: Student
Physical Appearance: Shaggy chestnut brown hair that leans to the left, hanging over one of his two emerald green eyes. Sun-kissed skin from lots of exposure to the outside world, and a lean athletic build. The back of his forearms and lowers legs are scattered with faded scars from rigorous training.
Casual Clothing: Normally wears a collared black jacket with a white undershirt, faded dark blue jeans, and black sneakers with white trim.
Hero Clothing: He wears and tight but highly elastic short sleeve shirt, a pair of durable black combat pants/boots, and a set of fingerless gloves with plated knuckles, all of which are matte-black in color. His forearms and shins are protected by thin plated armor, his eyes by a set goggles which are on his forehead unless his powers are active, and finally, a small oxygen tank resting in the middle of his back, a small holster attaching it to his heavy duty utility belt from the base, every item listed being a dirty bronze color, except for the oxygen tank, which is light grey with a clear tube attached to the side of it.
Personality: Katsuo has a habit of making light of every situation, a witty remark or offhanded comment always primed and ready. Despite this, Katsuo is rather friendly if you give him no reason to 'entice you' as he'd put it. Thankfully, Katsuo has the intelligence and skill needed to back up his unfiltered words, ready to take on anyone who comes his way.
Quirk: Titans Lungs- Katsuo's torso is made of highly durable, yet extremely elastic muscles, allowing him to expand his chest and inhale many times more oxygen than the normal person. This allows him to produce jet-streams of air that vary in size and intensity for vairpis purposes. Because of the rubber-like nature of his chest, Katsuo also has relatively decent shock absorption in that area, allowing him to take heavy hits and keep fighting with little to no damage taken. If his quirk is overused, it can cause him to hyperventilate, inducing dizziness, shortness of breath, and potential loss of consciousnesses, the tank of his back is used to revitalize him if he overdoes it. His abilities branch further than this, but I'll leave it here for now.
Backstory: Katsuo has always felt like he had a lot to prove, what with him being a first generation quirk user, his quirkless relatives often piled his mind high with there future hopes and dreams of a family hero, one capable of making a real name for himself. Katsuo now had the chance, and spent every day trying to improve in hopes of making his family proud as the first high-ranking hero of the Isamu household.
I may also create a teacher OC if any are needed.
