Q&A for How to Make a Deadpool Costume

Deadpool started out as a villain, but he has since tried to amend his ways and become a good guy (a member of the X-Men, specifically). His mental issues make it difficult, his approach is always unorthodox, and sometimes he slips back into his old ways, but he's trying his best to be a hero. However, due to his checkered past and unpredictable nature, many superheroes are unwilling to accept that he's changed and work with him, and some still view him as a villain.

You could, but some might be confused as to who you're supposed to be, since Deadpool's mask is red and black.
