Giant Bowser is a minor boss that appears in Super Smash Bros. Melee and Super Smash Bros. Brawl.

In Melee

Giant Bowser appears at the end of Adventure Mode, where he is fought at Final Destination. Under most circumstances, he acts as the final boss of the mode, and defeating him allows the player to finish the mode. However, if the difficulty is set to Normal or higher and the player arrives at Final Destination within 18 minutes without using a Continue, Giant Bowser will transform into Giga Bowser upon being KO'd. From there, the player must defeat Giga Bowser to clear the mode.

As a cosmetic change, Giant Bowser uses Bowser's black palette swap if he is fought on Normal difficulty or higher.

Extra appearances by Giant Bowser include an immensely large version that appears, controlled by the player, in Event 25: Gargantuans against the computer controlled similarly-sized DK. He also reappears in Event 42: Trouble King 2, where the player, as Luigi, must KO him twice. Finally, Giant Bowser can appear in Classic Mode as a random giant opponent in stage 5. Unlike other giant opponents fought on their home stages, Giant Bowser is fought on the Fountain of Dreams stage, usually belonging to Kirby.

In Brawl

Aside from the usual random appearance as a possible giant opponent on stage 8 of Classic Mode, Giant Bowser's only appearance as a minor boss is in Event 27: Three-Beast Carnage where he appears alongside Giant DK and a new giant enemy, Giant Charizard, attacking New Pork City.
