Mammoth

Peppermint was a postal worker from Covington, Indiana. He was a huge man, which earned him the name Mammoth at the office, and after getting fired from his job, went on a bloody rampage. He slaughtered his co-workers and customers alike, before committing suicide with a gun. In Hell, Peppermint transformed into a hulking ape-like creature as a result of his rage and fights with his bare fists.
