Ok this is pretty insane.I know what your thinking:"Yea right,this is a scam" or "What? yea right" or "Liar".Well think again because I actually had my brother record me playing as master-hand on my phone.
Ok,I'm going to make this simple and easy for you.If you don't have super smash bros. melee still,don't think this will work with brawl because it doesnt.At the character select screen,put p3 controller on the "Name Entry" sign and keep it there.Make sure p3 isnt on any character or it wont work.Now p1 can pick any1 he/she wants,but when your done choosing a character,put the p1 glove on the "back" sign in the top right corner of the screen.Now what your going to do now is get both p1+p3 controllers and press the A button at the same time.If this is done correctly it will take you to stage select.If not repeat the cycle until you get to stage select.Now the only place this will work in is of course Final Destination.Once it's done loading P1's character will appear and p3 will be appearing as master-hand.Note master hand cant move.But you can use all of his moves D-pad up,down,left,and/or right+A,B,C,X,Y,Z,L,and/or R buttons.P.S-If you let the time run out while someone is master-hand,the game will freeze.So I suggest you quit the battle when the narrator says "1".Hope you enjoy this cheat I found,took me 2-3 weeks to get this right.xD
