Melllvar is a "34-year-old" Star Trek fan who lives with his mother. He is a green energy being who collects all of the Star Trek things launched up to Omega 3 after it was banned from Earth. He makes the Planet Express crew fight the cast of Star Trek. He is extremely powerful: an attempt to destroy him by rerouting the ship's power supply only makes him stronger. Several times he tortures Welshy using a blast of energy and seems impervious to damage.
Trivia[]
- His name may be a reference to Marvel's character, Mar-vell.
