Chef Fujimoto

The Chef is the main antagonist of the indie game Octodad and its sequel, Dadliest Catch.

Backstory
Acting as a chef on a shipping boat in the middle of the stormy ocean, the Chef attempted to murder an escaped octopus and capture a stowaway women named Scarlet. However, he was knocked over board and both the octopus (who was thought to be a human thanks to his "disguise") and Scarlet fell in love and married, the flashback ending with the Chef swearing revenge upon the cephalopod.

Dadliest Catch
Still having a bitter grudge against the aquatic mollusc, the cook continued his hunt. When Octodad and his family all went to an aquarium, the Chef set up a trap for him and threw him in the tank, nude and out of his disguise. After taking the octopus' confused family to the empty cafeteria, the Chef attempted to expose Octodad's true species to his family, but was unsuccessful until the very animal he spoke of returned, showing his own family who he really is. A struggle between the two led to the entire cafe to catch on fire, but it was eventually put out and the Chef was thwarted. However, Octodad forgave the homicidal chef and the cook realized how much his family truly cared about him, even after recieving the knowledge that he isn't human. So, the Chef finally gave up his hunt and made peace with his former enemy
