Originally, the Grim Reaper was a purely technological-based villain with no innate superhuman abilities.

Necromancy: When he was resurrected he gained some mystical powers allowing him to re-animate the souls and bodies of the dead, either through Voodoo training received from the Black Talon or powers bestowed upon him byLloigoroth. The Grim Reaper has also performed various magically-based feats, including but not limited to: teleporting himself and others, summoning demons, creating illusions and clairvoyant viewing.
