Mutant Freak

The mutant freaks or feral super mutants were test subjects of Erkal, a mutant scientist

Background
Mutant freaks apparently were Super Mutants once, but were later morphed into piles of flesh, kept alive by electricity. Some of them are also kept in glass tubes. They were intended to be used as guinea pigs, which later could give clues on how to cure mutant sterility.

Appearances
Mutant Freaks appear in Fallout Tactics.
