Clive

The Clive is an alien race that presumably originate from the Planet Jacqueline S, the first of which is shown as a hologram in manga Chapter 2 and Episode 2 in the anime respectively.

History
The Clive is described as "not so beautiful", in it's truest form. The species are considered highly adaptable when it comes to mimicry, implying that they're capable of disguising themselves. It's not clear if this specifically is referring to their appearance or speech pattern, it's safe to assume they can shape shift in order to effectively stay disguised as other races.

Trivia

 * Although never making an official debut, Prince Baka confirms that he has one as a pet. It's unknown if the one from the hologram is in fact the same one being referred to.
