Anyway, I always felt like Brawl Snake was supposed to be an amalgamation of Solid and Naked. I mean most of his outfits were camo-like and he says "tasty" when he eats stuff. Plus the RPG-7 (forward smash) was a Naked weapon until 4 released like a month or so later.
His Side B can occasionally shoot the c3 butterfly from Snake Eater ---
