Biography
Death had an army of cultists on Earth known as Death's Messengers that carried out work for him while he was stuck in the Underworld. One was sent after Rumpelstiltskin, who had made a deal with Death to give him a piece of the Magic Mirror, a deal that was ruined when Rumpelstiltskin broke the mirror.

After being temporarily resurrected into dead bodies of his messengers by Carabosse, Death devised a plan with the witch to get him a permanent human body so that he could take over Earth completely. His other motivation was to get revenge on Rumpelstiltskin. Because of this, Alice tried to make a deal with Death that she would give him Rumpelstiltskin if he gave up on taking over Earth. Instead, Death went to make another deal with Rumpelstiltskin, where he would give the Underworld to him if he gave Death his human body for permanent housing of his soul. Rumpelstiltskin accepted the deal.

Death and Carabosse then began preparing for the ceremony that would transfer the souls of Death and Rumpelstiltskin, including branding Rumpelstiltskin's chest. Right when Rumpelstiltskin and Death swapped positions, however, Rumpelstiltskin's body was blown up, therefore killing Death and leaving Rumpelstiltskin as the new ruler of the Underworld.
