Event match 1: Trouble King is the first of the 51 event matches in the event mode of Super Smash Bros. Melee. It is more-or-less a straightforward 2-stock match between the player's Mario and the computer-controlled Bowser with unlimited time on the Battlefield stage.
After selecting Event 1 from the event mode menu, the match automatically begins with the player playing as Mario vs. Bowser on the Battlefield stage. The player spawns on the center of the stage's lowest level while Bowser spawns above the topmost platform. Both Mario and Bowser have two lives in stock. The stage has an unlimited time for completion.
The object of the match is to KO Bowser twice. Bowser is given an unimpressive AI, most likely Level 2 (or possibly even 1), compelling him to rarely attack, and is given a large handicap, allowing him to be knocked back somewhat easily, despite his weight.
- This is one of four event matches that take place on the Battlefield stage; the others are Event 36: Space Travelers, Event 37: Legendary Pokemon, and Event 44: Mewtwo Strikes!
- The "sequel" to this event match, Two Trouble Kings, appears in Super Smash Bros. Brawl, likewise being the first event match in that game.
