Galleom appears to be a giant, purple robot/cyborg which has simian features, and is also capable of transforming into a jet propelled tank labelled as his "Tank Form". He is covered head to toe in a heavy mechanized arsenal, possessing two rocket launchers as shoulder weapons, and powerful jets on his feet. He wears an iron mask that covers his face, as well as metallic arm braces over his bulky forearms. He is also quite agile in his simian form, capable of performing extremely large jumps, leading to the possibility that his jumps are jet propelled. In his tank form, he is much more compact, only being able to attack by either firing the missiles on his back, or simply by ramming into his foe at a high speed. As a last resort, he can set off a Subspace Bomb hidden within his head.
Role in the Subspace Emissary
Marth, Ike, and Meta Knight were the first to spot Galleom as he was traveling through the desert in his tank form. The trio quickly caught up to him and defeated him, knocking him down onto unstable ground which gave way, and Galleom landed in the Ruined Hall, where Lucas and the Pokémon Trainer challenge him. They manage to defeat him, and, in a last desperate attempt, Galleom grabs both Lucas and the Pokémon Trainer, starts the countdown on his emergency Subspace Bomb, then jets into the sky. Lucas manages to free both himself and the Pokémon Trainer by using PK Thunder, but in the process causes them both to fall a great distance as Galleom explodes. Meta Knight manages to catch the duo just before they land, then fly them away from the Subspace Bomb's blast. Galleom is then sucked into the Great Maze, along with the trophy of Wario, and revived; he must eventually be fought again in the Maze.
HP and damage taken
Galleom has two Trophies, one featuring his Robot Form (which is obtained by using a Trophy Stand on Galleom), and the Galleom (Tank Form) trophy, which is obtained by completing Boss Battles mode on Intense difficulty. As a side note, completing Boss Battles on Intense difficulty is the only way to get this Trophy in the NTSC version of Brawl, as using a Golden Hammer on the challenge square holding the Trophy will not work (this is not the case in the PAL version, where every box can be broken).
