The Cassiopeian Dream Eater is an extraterrestrial organism that Albedo attempted to infect Ben with in order to get his Ultimatrix in Night of the Living Nightmare, but ended up accidentally infecting himself and becoming trapped in a nightmare.
The Dream Eater is a strange creature resembling a jellyfish. It is about the size of a human head, with several thin blue appendages. Its body is purple with a pink patch in the middle, with a white and several purple patches in the middle.
When it has ensnared a victim, the purple and pink patches form a skull like shape.
Powers and Abilities
The Dream Eater feeds off the chemicals produced by the brain during stress and thus, once it attaches to a host, it traps them in a nightmare to feed off these chemicals.
In order to remove it, a Galvan doctor is needed, as removing the Dream Eater by force might rip off the host's face in the process.
