Mughi

ムギ

Mughi is a large, cat-like creature who occasionally joins the Dirty Pair on their missions. He possesses some skill with electronic devices, and Kei and Yuri typically depend on his assistance as a co-pilot or gun-runner while their spaceship, the Lovely Angel, orbits the planet they are visiting, though he generally plays a passive role in the Dirty Pair's adventures.
In the anime series, Mughi is portrayed more as a cat or small furry pet rather than the somewhat menacing creature depicted in the novels. According to the character designer, Mughi's name is an acronym for "Military Unit of Genetic Higher Intelligence".
