Nixxis

A nixxis is a pterodactyl-like bird that lives on the planet Dewrf. They are primary consumers and are equipped with a metal skin ability, allowing them to feel no pain when attacked. They are the arch enemies of the carnicels, and will do anything to put an end to them. Despite this, they teamed up with the carnicels in episode 14 and killed the mechanic by ripping his head off.
