Pupipi is a supporting character in Metal Slug 6.
Pupipi is one of the Mars People captured by the Invaders during their conquest on Earth. Placed inside a Mars Pod, it was later then freed by one of the Regular Army soldiers during their mission to storm the Invader King's hive.
Its Mini-UFO acts similarly to the Mobile Satellite, attacking the enemies midair when the player presses the fire or grenade button. Pupipi will not fire when using special melees (D+A). After firing twenty lasers, it will fly out of the map.
