Tested on Pit because he, Dark Pit, and Wii Fit Trainer are closer to the middle in terms of weight while Mario's slightly
lighter heavier - I could have used Luigi, Villager, or middleweight Mii - at center stage on FD/Omega stages on the 3DS. Moves that don't kill include Blaster, Explosive Blaster, Burst Blaster, Falco Phase, Fast Fire Bird, Reflector at center stage, and Accele-Reflector. The stupidest thing is Falco's Side Smash where there's a hitbox on his body while his arms slam down and arc over him. I am not going to attempt to hit with that since Uair and Down Smash's body (and head) hit is easier to land than a skinny pheasant's torso.
