Dwarf

From The Vault

The dwarfs of Fallout are just little humans that got messed up by too much radiation in the gene pool. They are pretty much similar to normal humans, but smaller. Compared to pre-War times, dwarfism is much more common after the War, likely due to the effects of radiation.

[edit] Appearances in games

Dwarfs appear in Fallout and Fallout 2.
