The Klagen (クラゲン Kuragen?) is a recurring enemy in the Sonic the Hedgehog series. It is a mass-produced, jellyfish-based Badnik created by Dr. Eggman.


Klagens are gray robots with purple and cyan coloration that appear to resemble jellyfish. It has a UFO-like disc for a head that has a single purple eye. It has two arms that hang down and two discs at the end of the arms.

Game appearances

Sonic Heroes

In Sonic Heroes, the Klagen will approach the player upon getting in range. If it hovers over a character, it will capture said character by suspending them in mid-air with a tractor beam. Each Klagen can only capture one character at a time. When captured, that character cannot be switched to, which is signified by a white restricted sign over the character's icon. If the leader is captured, the player will automatically switch to a random, available teammate. Once the player destroys the Klagen, the captured teammate will be usable again. However, if all three characters are captured by separate Klagens, the player will lose a life.

Sonic Rush

In Sonic Rush, the Klagens are regular enemies encountered in the Zones, but they lack their character-capturing skills from Sonic Heroes.

Sonic Generations

The Klagens also appear in the Nintendo 3DS version of Sonic Generations.

There is a gold variant that teleports the captured team member to a location farther ahead in the level after a set period of time in captivity. Tails' description of this robot is "If that Gold Robot captures one of us it will take them away, we have to destroy it before any of us get caught".

    • Sometimes the Klagen's programming will glitch and it will keep the Team Member forever until either the area is left or the robot is destroyed.
