the series are Dwayne, Raoul and Vyolet. Dwayne (voiced by David Herman) is a mutant with two noses and a large forehead. Raoul (voiced by Maurice LaMarche) is the "Supreme Mutant", the democratically elected leader of the sewer mutants. His most notable mutation is a third arm, which in his first appearance had grown in place of his right ear but above it in later appearances. Vyolet (voiced by Tress MacNeille) is a chain-smoking mutant with gills and a pig nose; she seems to be romantically involved with Raoul. Stephen Hawking Stephen Hawking (voiced by himself) made a guest appearance in the episode "Anthology of Interest I" as a member of the Vice Presidential Action Rangers (VPAR), who guard the space-time continuum. Along with Hawking at the end of the twentieth century they include Al Gore, Nichelle Nichols, Gary Gygax and their summer intern Deep Blue. He first appears as a customer at the pizzeria where Fry mistakenly believes him to have invented gravity for which Hawking accepts credit ("Yeah, sure. Why not?"). After learning of Fry's inter-dimensional experience, he arranges for him to be kidnapped by the VPAR. Hawking also appears in The Beast with a Billion Backs as his own head in a flying jar, leading a scientific convention organized to study and discuss a tear in the universe.

Apparently he has the ability to shoot lasers that stun people from his eyes; he himself is surprised, remarking, "I didn't know I could do that" after stunning Professor Farnsworth and Professor Wernstrom. He also makes a brief appearance during the "Future Challenge 3000" segment in "Reincarnation". Due to a debilitating, long-term illness, Hawking was unable to speak with his own larynx, but his computer-assisted speech device was a trademark voice in popular culture. Films' characters Lars Fillmore Lars Fillmore (voiced by Billy West) is a technician at the Head Museum in Bender's Big Score, where he met Leela and briefly dated her. He was about to marry Leela, until he discovered that a paradox can not be in the normal time line, and decided to cancel the wedding, because he was really a paradox-duplicate of Fry created when the original Fry who had travelled back to 2000 went back a
