The Dwarf Gekko is a small unmanned weapon from the Metal Gear series, first appearing as a mass-produced enemy in Metal Gear Solid 4: Guns of the Patriots (2008) and returning in Metal Gear Rising: Revengeance (2013). These scuttling machines are remembered for their unsettling vocalizations, somewhere between a giggle and a mechanical bleat, which made them stand out among the series' stranger enemies. Clips of the laugh circulate among Metal Gear fans and meme editors, who lift it out of context as a ready-made taunt for jokes about ambushes, betrayals and tiny but dangerous foes.
