Me (Ike) and my friend who was Marth were having a team battle with all items so he got final smash and he was recovering from below (mostly on left side) then when he missed the ledge and immediately after a few frames of a helpless state, some how he used his final smash but the critical hit turned out to be a dolphin slash(up-b) exept it went farther and was more powerful. Unfortunately, he self-destructed like how marths FS would usually self-destruct. Please don't complain because I have no idea how to do this! My friend did not remember which buttons he pressed (randomly pressing buttons during helpless state). I will not call this my "glitch" because you might have done this before. I just wanted to post this to let you know that there is a new Marth FS glitch.
