Master Hand
Master hand joins the fray. He acts exactly like any other boss character, by always having 1 stock and a stamina meter instead of percentage, he is completely impervious to knock back, and he can fly. His moveset is nearly identical to his moveset in smash bros ultimate, which means he is fully playable as well as a propper boss fight. While you can fight him on any stage, for the best experience possible, i recommend fighting him on a flat, platformless stage, like final destination, for the best experience. For a real challenge, put on team mode and make 2 of them for a master and crazy hand fight. If you have encounter any problems or glitches, you can contact me on discord with my tag, @xtra#3678.
