Event 42: Trouble King 2
From SmashWiki, the Super Smash Bros. wiki
This event match is a somewhat of a sequel to the first Trouble King. This is not as easy as Event 1: Trouble King. Here, Bowser returns; and he is extremely large. In addition, the player was Mario in the first Trouble King match. However in Event 42: Trouble King 2 instead of fighting Bowser with Mario; the player fights him with Luigi.
Due to the combination of Bowser's incredible size and the geometry of Poké Floats, it is more feasible to attempt to cause Bowser to SD rather than trying to KO him directly.
