Mantis

Mantises are mutated creatures in Fallout, Fallout 2, and Fallout: New Vegas.

Background
Mantises have grown in size due to exposure to radiation, and are commonly encountered in the southwestern United States. The giant variants of the Mojave Wasteland were experimented on in Vault 22. The females lay eggs in oothecae. Mantis forelegs are utilized for the mantis gauntlet, and can also be grilled or served with marsala.
