Hmmm some of the ones I'm thinking of may be a stretch but you could try to do a soul eater evans, near from death note or maybe you could pull off storm?
Gintoki from Gintama like the other person said may work but I think his hair has a blue tint to it?
That's all I know but you might have to smooth out or slightly style the wig for some of these so I'm not sure if any of them would be any good to you! ^^
Cons I plan to attend~!
Soul Eater Evans- 100%
Soul Eater Evans (Black Blood)- 100%
Len Kagimine (Normal)- 80%
Near (Nate River)- 30%
