Knuckle Joe from Kirby Super Star would be very cool in Super Mario Bros. Crossover. Here's my idea of power ups: When he's small, he can punch to damage enemies. By getting a mushroom, he gets bigger and can do a punch-kick combo by pressing the attack button 2 times. After that, his other power ups are: Smash Punch: He can use a extremely powerful punch, but its not that fast as his other attacks. This is his armor-piercing attack. Rising Break: He can use a uppercut. This damages enemies and works as a second jump. Vulcan Jab: He can punch very fast. I mean, REALLY fast. Is this good?
