OKAY GUYS.
This is
Hollace Knighting.
Age: 20
Hollace was a pretty outgoing, fun-loving guy when he was younger, but during his freshman year of high school (about fourteen years old at the time), he lost his right leg in a car accident. Despite going to physical therapy and learning how to walk with a prosthetic, he remains a pretty angry guy and whenever he opens his mouth, he sort of comes off as a asshole. In college, Hollace learns that he has the ability to run at super speeds and plans to use the power for the best. However, any time he runs, it causes him pain, therefore reminding him of what he lost.
Side note: because of the accident, he more than likely suffers from PTSD, resulting in nightmares/flashbacks.
I say he's sort of an asshole, but once he opens up, he's loyal and has a kind heart. I'm not positive about love interests.
edit: I figured that he probably has some bad habits to cope with his loss, so one of them will be smoking which will easily affect Remy. So there's a way in for those scenes as well as some nice bickering between the two.
