Grim Reaper
The Grim Reaper is a boss from Kingdom Hearts II.
Posing as the second boss from Port Royal, the Grim Reaper is a Heartless that is summoned by the Nobody Luxord to acquire the treasure of Isla de Muerta. Sora and company battled it twice--first aboard the Black Pearl, and then at the docks of Port Royal. During the second battle, it is invincible when treasure is out of its chest; when Sora uses Magnet to bring the medallions back into the chest, the Grim Reaper becomes vulnerable.
Despite its name, the Grim Reaper resembles a Aztec statue swinging a blade pendulum. However, this fits the Aztec theme of the first Pirates of the Carribean film on which the events of the first visit to Port Royal were based on. Furthermore, his appearance, minus the pendulum, appears to be based on the (real-life) Aztec god of death Mictlantecuhtli.
