Energy being

As Amy once said, the energy beings are entities of pure energy. They are aliens who have evolved beyond their physical bodies and, according to Bender, originate from another dimension that is big on musical theatre. These creatures have an electro-quantum structure which the Planet Express crew thought could be overloaded, but instead makes them grow. ((et|4ACV11}}

Hybrids
Various creatures resemble the energy beings. It is unknown if Melllvar and his mother are the same species as M5438, but, based on their dissimilar structures, this seems unlikely. The Robotic gas forms on the Robo-Planetoid are physically similar to them, and may be of a related species.

Characters

 * M5438.
 * Melllvar
 * Melllvar's mom
 * Robotic gas forms, possibly.

Trivia

 * They are based off the many in Star Trek.
