How do you complete 100-man Melee in Super Smash Flash?

One way is to use Lloyd and go to the far left or far right edges of the stage. Hold Up and repeatedly press P to use the spinning attack. Another way is to use Mewtwo and go to a far edge. Like Lloyd, hold Up and repeatedly press P. However, make Mewtwo face inward, so when enemies are running up to you, you can use ranged moves like Shadow Ball by holding Down and pressing P.
