Monster Ock (sometimes spelled Monster-Ock) is the final boss in the N64, PC, PS1 and GBC video game; Spider-Man: The Video Game.

Monster Ock's Creation
After Spider-Man defeats Carnage, the symbiote suit rejects Cletus Cassidy. The suit then processed to drip into the lower floor of Doc Ock's lair. The suit ended up attaching itself onto an unconscious Doctor Octopus. When that happened Doc Ock became the unstoppable Monster Ock.

After Monster Ock attacked Spider-Man and tried to kill him, Spidey, instead of fighting him, is forced to flee the monster as Doc Ock's underwater lab begins to blow up. Monster Ock pursues Spider-Man through vents lining his facility.

Monster Ock's Defeat
Eventually the Monster Ock is defeated after he is engulfed in an explosion. Doc Ock's mechanical arms were severed from his body, the Carnage symbiote retreats into the exploding factory, but Doctor Octopus otherwise survives.
