Mystique from X-Men
X-Men are completely awesome, and Mystique is one of the coolest characters in their universe. Whether she’s a villain or a hero, she exudes coolness in every way. It might be a bit of an ordeal to get painted blue for the occasion, but a red top and red pants are pretty easy to come by. If you’re willing to go through getting’ turned blue, this is a great choice for cheap cosplay!
