Borderline

Todoroki Izuku: Character Analysis

^Thats the song that this fic is named after.

********************************

Things to know:
In this fic, Izuku is Shouto's twin brother and is abused by Endeavor a lot worse than Shouto is, even in canon, leading to him not really being able to handle being around large groups of people and he hates loud noises. He does not like being separated from Shouto, even when he knows his father is not around, because it was always when they were separated that Endeavor was the cruelest.
Physical appearance:
Hair: Izuku wears his hair in much the same style as canonical, if a little less floofy. His hair is green (naturally red).
Eyes: same as Shouto's
Height: 5’7"
Other: other than Izuku's naturally red hair, shorter height, and chubbier face, he and Shouto are identical. However, Izuku doesn't have any scars quite as prominent as the one on Shouto's face. Not that are quite as visible anyway. He does have a hand shaped burn mark on his forearm, just below his elbow. He got this burn from his father one day when he tried to sneak into the training room to watch Shouto's training when they were seven. Because of this, he doesn't normally wear shirts with short sleeves and when he does, he typically wears a long sleeved shirt beneath it.
Quirk:
In this fic, Izuku has inherited Rei's ice quirk. Although it is stronger than Shouto's ice.
Where he didn't quite inherit Endeavors fire quirk, he can still produce heat from the palm of his left hand, which can reach fairly high temperatures.
Despite Izuku being undeniably stronger than Shouto, seeing as his brother refuses to use his fire, Izuku is still considered weak by their father and Endeavor even sees him as being unworthy of being a part of the family.
Other Crap:
Where canonically, Izuku and Katsuki grew up together, in this AU they don't even meet until their first day at UA, making their relationship(😉😉) very different, although they still don't get along very well at first because Katsuki thinks that Izuku and Shouto are both just spoiled brats and aren't worth his time, however, this changes after the sports festival.
Despite Izuku basically being a completely different person in this AU, he is still very into hero's and still knows a lot about them, although not as extensively.
Izuku does not get along well with others and prefers to be alone(alone as in just him and Shouto), therefore not befriending nearly the entire class as he does in canon, although he does later become good friends with a select few.
