Event 2: Landmaster Ignition
From SmashWiki, the Super Smash Bros. wiki
Landmaster Ignition (ランドマスター起動, Landmaster Launch) is the 2nd solo event match out of a total of 41 in Super Smash Bros. Brawl. In it, the player controls Fox, who is perpetually ready to unleash his Final Smash. Fox must KO Meta Knight and Sheik on Corneria, but because they don't take much knockback in this event, only the Landmaster is able to KO them. Considering that only one KO is necessary to complete this mission, it is perhaps the game's easiest event match, even when put on hard difficulty. Failing to score at least one KO results in a failure. Sheik and Meta Knight are also given a huge buff to their attacks, so they can inflict more knockback.
