The FINAL Final Battle is the forty first and final event match in Brawl. In this final event match, The player is pitted against Snake, Sonic, and Giant Mario. All characters have two stocks while fighting on Final Destination. The player must knock out all three of these foes to win this event match. The foes will team up on the player's character and cannot harm each other in this event. The event pays slight homage to Melee's final event, Event 51: The Showdown, seeing as the player is given to face two characters and one sized/overpowered version of the third one on Final Destination.
- Mario, Sonic, and Snake are the official mascots of Nintendo, Sega, and Konami, respectively.
- The fact that Mario is giant may be a reference to the fact that Super Smash Bros. Brawl is a Nintendo game, and Sega and Konami are its third parties.
