Philip originally posed as his brother Ramon the original Senor Muerte. Working with Tarantula he planned to smuggle Madbomb parts. Their plot was uncovered by Ken Astor who under the alias Al Avison enlisted the aid of Captain America. Muerte and Tarantula managed to get the drop on Cap knocking him out and throwing him in a river. Captain America recovered in time to capture them before they could carry out their plan, but not before they killed Ken Astor.
Philip next turned up helping his brother Jaimie run various casinos. In revenge for killing their brother as well as disrupting their gambling operations it was decided to kill Power Man and Iron Fist. Muerte made several failed attempts to kill them, but all it ended up doing was bringing them to the brothers casino where they were defeated and captured.
