Pupa (Metal Gear Solid Peace Walker)

The Pupa is an AI weapon that serves as a minor antagonist in the video game; Metal Gear Solid: Peace Walker.


In 1973, the Pupa was developed by Huey Emmerich as one of three prototype AI weapons for the Peace Walker. At some time between 1973 and 1974, the Pupa was deployed against the Sandinista unit that were hiding at Costa Rica, and apparently killed several of the members.

After Snake failed to prevent Hot Coldman from relocating the Peace Walker's frame from the Mount Irazu facility, Coldman dispatched the Pupa to take out the intruder. The AI would usually foreshadow its attacks with a burst of song, using its speech synthesis system. However, Snake (with some help for Huey) was able to decommission the Shagohod-like AI weapon.

Powers and Abilities



  • The Pupa bears a striking resemblance toward the Shagohod from Metal Gear Solid 3: Snake Eater.
    • Despite this, Snake didn't seem shocked to see the Pupa greatly resemble the Shagohod.
  • The Pupa was also known as, by the Sandinistas, el galapago, which means "Tortoise" in Spanish.
