Trivia

 * Sprited by former artist William Data AKA Waffles.
 * Many of his names seem to be letters of the Greek alphabet such as Alpha, Beta, Gamma, and Omega.
 * Some of his names may be references to other robots:
 * Fender is a reference to Bender from Futurama.
 * T-3E0 is C-3PO from Star Wars.
 * A.N.D.Y. is HAL-9000 from 2001: A Space Odyssey.
 * Niner-7 might be Seven of Nine, a former Borg (cyborg alien) from Star Trek: Voyager. It could also be the N7 special forces from Mass Effect (though in the NATO phonetic alphabet, "N" is "November", and "Niner" is for "9").
 * One of his quotes "Have you defeated the Wall of Andrew?" may be a reference to one of the Guide's names, Andrew, and his use to summon The Wall of Flesh
