Conquerons
The Conquerons made their debut in the episode Zapp Dingba, where Zapp Brannigan ticked them off by misspeaking their language; instead of offering congratulations, he said he'd like to spank the Admiral's sister with a slice of bologna. They seem to be aggressive in nature and easy to anger, though forgiving enough when it comes to imbecilic space captains. Munda, Leela's mother, offered to translate their language, which is crude in tongue and delivery. They look like sharks.
