History
Nobody knows anything about Hayden Fonda other than the information above. He just kinda... showed up one day. No past education, no acceptance into the academy, he just... showed up at the entrance exam and passed with flying colors. And as much as they tried to turn him away, the school system ultimately just shrugged and let him in, though under a watchful eye.

Hayden is actually a pretty good guy, but he's very unapologetic. He's accidentally destroyed quite a number of things and never apologized for them. While it was dismissed at first, due to his Semblance not being under full control during the first year or so, nothing changed even when he had it under control. Because of this, he's ticked off quite a number of people, students and teachers alike.

His Semblance, simply named Crash, gives him the ability to destroy just about anything. During his first years of not having control over it, he destroyed things as large as doors and walls, to things as little as pencils and notebooks, the latter mostly while he was using them. And the former still gets destroyed on occasion, but only when he is drowsy. In quite a few classes, he walked straight through a freshly destroyed wall, similar to that of the Kool-Aid Man.

Hayden doesn't use any weapons, mostly in fear of destroying them. Instead, he relies on his muscles and CQC. He's very adept in hand to hand combat, enough to rival even Felix. And as the years went by, he adapted his fighting style with his Semblance, making him even more dangerous.

Overall, Hayden is a very pleasant guy, but he's hard to like, as well as a very strange person. It took a long time for his team to warm up to him, even though he warmed up to them easily, even Felix. He's genuinely confused by all the hostility coming his way, but he doesn't pay attention to it, much to everyone's displeasure. He considers himself the best he can be, and thinks that if people can't accept that, they just have to deal with it.

Relationships
Team FSHA
Felix Scout: Despite Felix's first impression, Hayden saw it as a personal challenge. He can prove to this guy that he and the others were capable of so much more than Felix thought. And in a matter of ways, Hayden succeeded. He considers Felix a close friend.

Scarlett Justine: Hayden is completely oblivious to Scarlett's curiosity and suspicion. But he's also completely unaware of her animosity. He could literally tell you she's one of the nicest girls ever while said girl is biting you on the arm. As said, he's a very strange person.

Ava Lillian: Hayden finds Ava adorable, as well as a decent fighter. He's also oblivious to her being intimidated by him. Are you sensing a pattern yet?

Team ACID
Hayden doesn't really interact with ACID all that much. He thinks they're cool and all, but mostly just stays out of their business. And while he'd happily join a raid on a SDC factory, he's scared to give everyone away with how much damage he could potentially cause.
