Sea of Blood
Geras is an artificial construct created by Kronika to serve as her primary enforcer. Named after the Greek deity of old age, his powers are based around manipulating sand and time. The story mode of "Mortal Kombat 11" establishes that he also possesses regenerative abilities, effectively rendering him immortal. As the Earthrealm heroes are unable to kill him, Raiden defeats Geras by throwing him into Netherrealm's bottomless Sea of Blood. The "Aftermath" expansion, however, depicts Geras being killed by Shao Kahn, despite his immortality powers.
