Galleom

Galleom is a boss that appears in Super Smash Bros. Brawl and Super Smash Bros. Ultimate. It is a purple-skinned ape-like monster in a robotic form. Galleom possesses the ability to "transform" between a futuristic tank form and an upright robot.

Super Smash Bros. Brawl
Galleom is first fought by Meta Knight, Marth, and Ike. After the battle, Galleom takes a huge leap and lands near to where Wario was once turned into a trophy. However, the floor breaks from the impact of the landing, and Galleom falls into The Ruined Hall. Galleom then sees Lucas and Pokémon Trainer, and fights them. After the second battle, Galleom grabs Lucas and Pokémon Trainer and opens its cranium, revealing a Subspace Bomb. Galleom launches into the air with them having only 15 seconds left, intending to take them with itself to its death.

Lucas uses PK Thunder to break off Galleom's arm, and frees them. Right before they land, they are saved by Meta Knight. Galleom, however, meets its end with the explosion of the Subspace Bomb. Later though, players must fight it for a third time in The Great Maze. Although it was fought two times earlier in the game, players only need to fight it once in the Great Maze.

The Galleom trophy is earned by use of a Trophy Stand. To get the trophy of the tank form of Galleom, the player must clear the Boss Battles game mode on Intense difficulty level.

Super Smash Bros. Ultimate
Galleom returns in Super Smash Bros. Ultimate in the World of Light mode. It also serves as one of the final bosses in the game's Classic Mode where it is fought by Wolf, R.O.B., Snake, King K. Rool, Dark Pit, and Min Min. It is also fought in Mega Man's Classic Mode route, though it is not the final boss.

The Galleom spirit can be earned by defeating Galleom in World of Light. It is an Advanced-class Neutral-type primary spirit that has three support slots and strengthens the user's fist-based attacks.

Galleom also makes a cameo in the Home-Run Contest, where it can be seen flying in space in the background.

Trivia

 * When The Great Maze is completed, the player cannot rematch Galleom at The Wilds (Part 1). It can still be rematched at The Ruined Hall, though.
 * Galleom is the only boss in The Subspace Emissary that is fought more than once before the Great Maze.
