Event 51: The Showdown
Event 51: The Showdown is the final Event in Super Smash Bros. Melee. This Event Match gives you a choice of any character. You'll have 3 stock, and your opponents, Giga Bowser, Ganondorf, and Mewtwo also have 3 stock each. You play on Final Destination, which you unlock after clearing this. To get this Event Match, clear the first 50 events.
Strategies
Jigglypuff
Damage Giga Bowser a little bit, then jump into him and KO him with Rest (Down B). Do that 2 more times, and then try and do the same to Ganondorf and Mewtwo. You can also trying flying around waiting for good items to show up, though Resting is quicker. Since Ganondorf heavily overuses his up+B, you can Rest him if you can coordinate his landing point.
However, if the Rest move were to miss, Jigglypuff would simply fall asleep, leaving her vulnerable to attack.
Peach
Use your floating skill and parasol to float over their heads, waiting for any good items to appear.
Fox/Falco
Go to the edge of the stage and start using the blaster (B) on them to weaken them. When they get near you, Fire Fox/Bird (Up B) or Fox Illusion/Falco Phantasm (Left/Right B) over to the other edge and reapeat. Continue this. Once they're at a considerable damage percentage, attack them with a smash attack.
With Fox, it's best to get Giga Bowser out of the way first, because then all you have to do is keep firing your laser at Mewtwo and Ganondorf until they are around 80-90%, and then finish them off with an up-smash. This is simple because they'll keep putting their shields up. Your blaster will eventually break them, thus enabling you to come in with a charged Smash attack. (Fox's Up-smash is the 2nd most powerful in the game, with only Pikachu's being stronger.)
Fox/Falco 2
Fire Fox/Bird (Up B) all over the place, using it to dodge and recover. It's possible to do a run with no stock loss like this.
Zelda
Spam Zelda's dash attack on Mewtwo, while using Zelda's Fsmash on Giga Bowser. Giga Bowser's frame is so large that he cannot escape it. If you get knock off the stage, return with a Nair, not a Fair. If your Fair is slightly off, you'll be punished. A Nair is helpful because, once again, due to his large frame, bowser can not escape it, and it racks up damage fast. Zelda's up&B is a great thing to help you when you're being spammed. The first hit of the move will send your enemy's upwards, letting you get away safely. Once their damages are high, try a SH Fair, Dsmash or Fsmash.
How TO KO'd easily
Mewtwo: When at the start of the battle, try to stall for a few seconds, letting Ganondorf walk towards where you are currently. Then head left and just off the edge to let the enemies walk to the edge. Stall them by keep not being on ground(Use Kirby or Jigglypuff for best results) and Mewtwo should be charging while you are far from the edge. Giga Bowser and Ganondorf should push Mewtwo off while he charging and get Ko'd. Try not to let Mewtwo fully charged and Mewtwo must be closing to the edge for this to work. Repeat this process three times for Mewtwo to get defeated.
Ganondorf: Hang at the edge and keep hanging on. If Ganondorf is closing to you and the edge, jump high and Ganondorf will likely (Up+B) you. If he misses, he will fall off the stage.
Giga Bowser:Go to the edge at the beginning and then Giga Bowser might do a (Down+ B)on you. Shield yourself with the Z button,and then Giga Bowser can slide fall the edge and get KO'd. He can also get push off the edge while breathing fire and can fall off while attacking you when you are far from either edge and fall and do a spin attack, but fail or to a slash while it is near one edge and KO'd itself..
World Record-
The quickest way ever is to use Mario, continuously drop down, use up b to edge hog, Mewtwo and Giga Bowser kill themselves, Ganondorf is a bit harder but he also kills himself sometimes also; exploit the dumb computers.
