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


Mantises are mutated Mantis religiosa. Before the Great War, they could be found in southern Europe, all over the north-eastern United States and Canada to the Pacific Northwest and range from 5 cm to 7.5 cm.


After the Great War, two divergent mutations can be seen. The variant seen in New California comes from an exposure to radiation and the mutated F.E.V. of the West Tek Research Facility coming from the air.[1] The other variant seen in the Mojave Wasteland is created by the horticultural experiments of Vault 22.
