Reasons why I think he'd be PERFECT:
1: He'd be the first and only character to originate from a vehicular-combat game.
2: He appeared on the GameCube, a Nintendo console.
3: He originated from a video-game.
4: He has a toy dedicated to him.
5: He hails from a destructive franchise that uses over-the-top and cartoony weaponry like Smash does.
6: The game he hails from has a T rating, so it's alot more reasonable and likely to happen than requesting an M-rated character like Sweet-Tooth (Even though Snake was ok to add for some reason)
7: He has alot to him. Cel Damage has 3 different victory themes they could use for him; numerous weapons for his arsenal including the fact that he can breathe fire; there are alot of environments from Cel Damage they could choose for him, and alot of music, as well; and, he's the main character. He's the face of Cel Damage. And, the game even has an emblem they could use for him.
8: Lastly? It would give Cel Damage more notice, and get us a step closer to that Cel Damage sequel we never got where you could exit your vehicle and run around, freely.
