Regro Burnedead  

, レグロ・バーンデッド

Regro rescued Mash from being abandoned on a bridge when he was just a baby. He raised him in his own home in the woods, where he taught him not to go into the city because he didn't have any markings and would be taken away if someone found him there. Regro trained Mash to become physically strong so that he could protect himself.
