Meet Charlie Brawl, the result of a child tormented by self-loathing and insecurity, who finally said and enough was enough and hit the gym for five hours a day for ten years to grow into the behemoth you see before you.
This is a piece from DeviantArtist MgnZ, who just wanted to imagine Charlie Brown as a character in a fight game, and the move showcased on screen is him unleashing his rabid beagle Snoopy on his enemies.
Sadly, this appears to be the only one in the series, but I would LOVE to see more. Lucy? Linus? Patty? Pigpen? What would they look like if they got all Street Fighter-ized?
