Deadman (DC Comics)
Deadman appeared briefly in Jeph Loeb's "Absolute Power" story arc in "Superman/Batman", in which he attempted to possess Superman after he and Batman killed off all the monks of Nanda Parbat (under orders from their adoptive parents, who saw the monks as a threat to their plans in an alternate timeline). Deadman is prevented from using Superman's strength to kill Batman when Batman uses a spell from Zatanna to trap Deadman inside a crystal.
