Twin centaur

The twin centaur is a creature that was cut from Fallout 3.

Background
They were conjoined twins, created in the centaur process. This caused personality conflicts between the two "twins." For example, one would like country, the other rock, and roll. When none of its enemies were present, they were likely to beat on each other (see concept art).
