Octobots are series of robots in EarthBound created by the main villain Giygas. They appear in various versions late in the game as very powerful enemies. Unlike some other alien and robot enemies, one Octobot appears in Mother 3.
Octobots are mainly composed of a sphere with a visor from which they can attack the enemy. They also possess four tentacle-like parts.

Mechanical Octobots are more powerful versions seen during the Onett Invasion near the end of the game.
