Ok, I know this isn't my RP and it's not up to be do decide who is in and who isn't, but I feel the need to state the problems I have with this character.

A) With the exception of the quirk, it is a complete ripoff of the Black Panther, you even used pictures of the actual Black Panther for the appearance, which imo isn't very creative.

B) Your quirk is way too overpowered.  Being able to copy the quirks of anyone he sees, no matter how complex they are, with the only downside being he has to see it is way too overpowered.  He could quickly become way too powerful just on the first day, watching everyone use their quirks to show their potential.  And it would make it hard for anyone else to compete with him or stand out, because he'd be able to do exactly what they could do, as well as what everyone else could do.
