In this event, a player must defeat 4 giant Wire Frames and a Jigglypuff. Each has 2 lives. The only item that will appear is the Poké Ball. Every Poké Ball holds either a legendary Pokémon or a Wobbuffet. The only character on the other team who can use a Poké Ball is Jigglypuff, and in fact it will do nothing else, while all the Wire Frames ever do is attack the player's character. The goal of this event is to defeat both Jigglypuff and the Wire Frames.
Jigglypuff should be the first character the player should KO, as if she gets a Legendary it will have a huge negative effect on the player. Jigglypuff can be easily defeated by using the Poké Balls. The Wire Frames should be dealt with last. A good Pokémon like Moltres and Lugia will KO the Wire Frames fast, while others like Raikou and Ho-oh will raise their damage percentage to a point where you can KO them easily using either smash attacks or other moves with high knockback, like Rest or Stone.
The player can also use Ganondorf's no-glitch Cruel Melee strategy to KO the Wire Frames besides Jigglypuff in the beginning. Go to the edge, wait, down smash when they all come down, then go to the Poké Balls.
The world record strategy involves the use of Mewtwo's Confusion pull-through glitch, wherein if Confusion is used on a standing opponent as Mewtwo falls by the platform the opponent is standing on, the opponent will be pulled through the platform. Use this glitch to KO as many Wire Frames as possible throughout the match. Ignore the first Poké Ball, as it almost always contains a Wobbuffet, but grab the second before Jigglypuff does.
- Captain Falcon is also a good choice thanks to his extremely fast dash and air speeds, and the fact that he's heavy and powerful.
- During the battle the music for Poké Floats plays.
- Even though the title of the event says "Legendary Pokémon", you can still damage the enemies normally. It's just the Pokémon will do most of the damage.
- Mewtwo is the most famous character used for this Event Match, as it is also a Legendary Pokémon.
Beating this match will unlock the secret character, Pichu.
