Bender's factory-set height is just over 6 feet (1.8 m) tall, including his antenna, and just under it without. He flipped a coin to decide his color, ending up with fog hat gray rather than gold. His body has a shiny metal behind, two legs, two Extens-o-matic arms with three fingers each, a head with two replaceable eyes shaped like light-emitting diodes, and a mouth used for fuel intake and voice communication. Bender claims he also has a nose, but he chooses not to wear it. Bender's human-like characteristics are reinforced by his display of behaviors often regarded as exclusive to humans, such as whistling, snoring, having bloodshot eyes, crying, feeling physical attraction, being tickled, and dreaming.
