Geemers (ギーマー, Geemer) are enemies in the Metroid franchise.
Geemers are basic enemies from many Metroid games. They originally debuted in the first game in the series with the name "Zoomer", although it was more accurately re-translated as "Geemer" in Super Metroid; Metroid Prime would later establish Geemers and Zoomers as related species. They are not immediately hostile to Samus, and simply move along the borders of terrain. Geemers are generally weak and easily dispatched by a few shots.
The Smash Run appearance of the Geemer is based on its design in Other M, which in turn is modeled after its sprite from Super Metroid.
Geemers appear as enemies in Smash Run in Super Smash Bros. for Nintendo 3DS. They move along the shape of the terrain, often appearing on soft platforms. They do not actively attack the player, but they deal minor damage on contact and cause meteor smashes if the player is below them. It is best to dispatch them with projectiles or other long-range attacks, as attacking them directly will also hurt the player.
The Geemer trophy is exclusive to Super Smash Bros. for Nintendo 3DS.
