The Parasite Cage is an Emblem Heartless that is found in Kingdom Hearts and Kingdom Hearts Chain of Memories. It is the boss in Monstro.

Story[edit]

Kingdom Hearts[edit]

Sora and Riku find Pinocchio trapped in the Parasite Cage.

Sora, Donald, Goofy and Riku hear Pinocchio yell in fear from Monstro's Bowels. They race inside to find Pinocchio trapped inside Parasite Cage's stomach. The quartet give the Heartless a pounding to force it to spit out Pinocchio. It succeeds, making it regurgitate Pinocchio into an opening in the "floor", which leads back to Monstro's mouth. Riku immediately follows, taking Pinocchio captive to find out if the loss of his heart to the Heartless may be able to help him restore the heart of another. Riku heads to the stomach to examine Pinocchio.

Inside the stomach, Riku attempts to persuade Sora to join forces with him to save Kairi but is refused. Jiminy checks on Pinocchio, with the bond between their hearts restoring Pinocchio's heart. Riku is surprised by the result, just as Parasite Cage returns, seeking to continue its meal. This forces Riku to retreat through a dark corridor, while the others battle the Heartless. Upon defeat, Parasite Cage causes a chemical reaction in the stomach acid, which makes Monstro sneeze out the people trapped in him, including, Geppetto and Pinocchio.

If Monstro is visited after locking the Final Keyhole, Riku does not join the first fight against Parasite Cage and is told by Sora prior to the second battle that he knows he's not Riku.

Kingdom Hearts Chain of Memories[edit]

Parasite Cage is seen in Castle Oblivion as a figment of Sora's memory in his memories of Monstro. It captures Pinocchio when he tries to escape from the danger that was coming. Sora then fights the Heartless until he manages to knock it out. After Sora convinces Pinocchio to act brave, Pinocchio fights his way out of the Heartless until he escapes. After the Heartless disappears, Pinocchio reveals that the monster spat him out when he started fighting back and that Sora and his friends should try that on Monstro to help him and Geppetto escape.

The Parasite Cage also appears to Riku, as a figment of his memory and a representation of the darkness within him.

Design[edit]

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. Its appearance is also similar to the Prison Cage from Final Fantasy IX.

Strategy[edit]

Kingdom Hearts[edit]

The Parasite Cage mainly uses its tentacles to attack opponents. It attacks by swinging them or slamming them on the ground. It can trap enemies in the mouth on its body. It can also suck Monstro's stomach acid through its tentacles and spit it out through the top head.

First battle[edit]

At the start, remain on the platform and lock on to the Cage's head, shooting Fira or Gravity spells at it. Keep doing this until it's beaten and escapes. If Sora needs to recharge, either use an Ether or attack the head and cage with the Keyblade until he's regained enough MP. Riku will aid Sora in this battle, making him the only fellow fighter in the battle. After winning, Goofy learns the Cheer ability. Note that if Neverland is completed first, Riku will not appear and will not be there to help.

Second battle[edit]

This fight is much the same as the last one, but the Cage has developed a new poison breath attack. When the Cage gets tired and sags backward for a moment, its mouth will open. Bash it with the Keyblade and try to execute a couple of flying combos during this time. When it recovers, return to the normal strategy of casting spells at the head. Eventually, it reverts to its old strategy, and Sora can get closer to smash it with the Keyblade. Be careful not to step in the green acid surround the field, as it will damage Sora. After the battle is over, Sora and Donald will learn the Stop spell. The party is then automatically ejected from Monstro and returns to the Gummi Ship.

Kingdom Hearts Chain of Memories[edit]

In both Sora's and Riku's battles with the Parasite Cage, there will be four revolving platforms, floating on digestive acids. Sora should prefer using Fire attacks to make Parasite Cage drop a Gimmick Card. Using the Gimmick Card will cause the four platforms to disappear, and make the acid harmless. Once it ends, the platforms will reappear in their original size, even if previously made smaller by Both Hands Strike. Avoid stepping in the green acid as it will deal damage to Sora/Riku, and cancel their card in play.

Reverse/Rebirth[edit]

Since Riku obtains the Monstro world card within the first few stages of the game, defeating the Parasite Cage is simple. The only thing Riku needs to do is successfully fill the Dark Points gauge bar up to 30 by breaking every single card. That way, the enemy can also drop a Gimmick Card. After that, attack the Parasite Cage—simple attacks, sleights, or anything else. In addition, Riku has the Search Ghost enemy card to heal him each time he strikes it.

Kingdom Hearts Re:Chain of Memories[edit]

The battle is relatively the same as the original game. The acid no longer cancels the cards in use, and the Gimmick Card now removes the acid. The Parasite Cage has a 15% chance of getting stunned for 8 seconds when hit with a combo finish, Blitz, Lethal Frame, Ars Arcanum, Ragnarok, or Fire-based techniques, and a 100% chance when suffering a total of 7 card breaks. When stunned, the Parasite Cage will drop HP prizes for every hit landed on it.

Reverse/Rebirth[edit]

The same tactics apply to Riku in this game as well, but he should prioritize avoiding stepping on the acid when in Dark Mode, as he loses 5 Dark Points when he takes any damage, and continuous hits will make him revert to normal quickly.
