–Alcazar in A Bicyclops Built for Two
Alcazar was a shape-shifting alien whose goal was to "make it with five weirdos, and have them clean his five castles". He was briefly engaged to Leela, when he convinced her that they were the last of their race. Fry and Bender revealed him as a fraud when they ventured into the "Forbidden Valley" and discovered the four other aliens he was to marry that day.
He also owns a pair of Lightspeed Briefs.
