Horrible Gelatinous "H.G." Blob (voiced by Maurice LaMarche) is a three-eyed, green, translucent, ill-tempered alien. He first appeared in the season one episode " The Series Has Landed " in a commercial the Professor made for Planet Express. He contemptuously refers to humanoids as "solids" and ridicules their one-way digestive system. In " The Route of All Evil ", the Horrible Gelatinous Blob has a son named Brett Blob, who regularly bullies Cubert and Dwight. In Futurama: Bender's Big Score he, or someone of his species, appears on the twenty dollar bill. In "Proposition Infinity", he, or someone of his species, was shown to be in an "interplanetary" relationship with a human woman.
