Journal EntriesEdit

Kingdom HeartsEdit

Heartless that appeared inside Monstro. It's known to swallow its enemies. Sora and the others rescue Pinocchio, who was trapped inside it.

Kingdom Hearts: Chain of MemoriesEdit

Sora's Story

A Heartless that dwelled inside Monstro.

The Parasite Cage is quite the gourmand and eats anything in its path. Pinocchio figured out how to escape Monstro after getting gobbled up by it.


A Heartless that dwelled inside Monstro. It appeared before Riku as a token of the indelible darkness in his heart.


Kingdom HeartsEdit

The Parasite Cage was a Heartless sent into Monstro to find and capture the heart of Pinocchio and possibly locate Monstro's. It captured the puppet when he ran away from Riku during their game of tag. However, before it could succeed in escaping, Riku, Sora, Donald, and Goofy battled it in Monstro's Bowels. Eventually the Parasite Cage spit out Pinocchio and climbed away into Monstro's depths.

It was thought it stole Pinocchio's heart, but Pinocchio recovered in Monstro's stomach after being taken hostage by Riku. Parasite Cage returned, stronger than ever. It battled Sora's group once again, but was dealt defeat, releasing its captive heart. However, this caused a chain reaction in the stomach that made Monstro sneeze out Sora, Donald and Goofy to Agrabah while Pinocchio and Geppetto ended up in Traverse Town.

Kingdom Hearts: Chain of MemoriesEdit

The Parasite Cage fills a similar role in the memory version of Monstro. After Sora and company catch up with Pinocchio, the Heartless drops from the ceiling and swallows him. Sora and company defeat the Parasite Cage with relative ease.

While unconscious, the Heartless still has Pinocchio captured. He struggles and it spits him out, giving him his idea for escaping Monstro. The group goes to fight Heartless in Monstro's throat and the whale spits out Pinocchio and Geppetto.


The Parasite Cage's main body is a large, magenta blob with glowing yellow eyes and thin, rounded teeth that resemble prison bars. This body rests on a flower-like base that is violet and aquamarine. A much smaller pink head rests on top of the main one. This second head sports a jagged mouth, glowing yellow eyes, two short, dark purple spikes under its mouth, and a curled, magenta antenna on its head. Two long, aquamarine tentacles sprout from either side of the second head and end in violet "hands" with three fingers, each with a dark purple spike on it. Its Heartless emblem is between its eyes.

In Kingdom Hearts Final Mix, The Parasite Cage's main body is light orange, as is the antenna on the smaller head. The smaller head is light tan and the small spikes on it and its hands are blue. Its arms and base are pale green, its hands are yellow, and the flower-like section of the base is violet and lavender.


The Parasite Cage's name reflects its apparent great appetite and the fact that it is fought inside another living creature. "Cage" clearly references its mouth, which resemble prison cell bars, and its ability to capture opponents.
