Livian

Livian is a female servant robot. She is the companion or girlfriend of Atlas in the 1980s version. She doesn't want Astro and Atlas to fight because they are brothers.

She has never fought anyone in the whole series due to her lack of the Omega Factor.

In the series, she is rebuilt several times by Atlas once after being completely torn apart, and again after being caught in one of Atlas's stronger attacks during a battle with Astro Boy.

She is not evil like Atlas. Livian has alerted Astro many times of Atlas' plans, and is the one to discover that Astro and Atlas are brothers.

Trivia
Livian did not appear in the 2003 series.
