Fiction

IDW Beast Wars comics

The Celestials charged the robot Moon with observing the events transpiring on the planet Gaea for them. When the battle between the forces of Lio Convoy and Galvatron grew to be too dire for Moon to stand any longer, the robot followed his moral compass and disobeyed his orders, taking an active role in events. For this the Celestials "excommunicated" him and he can no longer contact them. Beast Wars Sourcebook 2

Trivia

• The use of the term "excommunicate" in this context is odd and suggets something of a religious nature to the Celestials. It strongly suggest some sort of religeous context. Whether they are a religeon, are "gods," have delusions of godhood or some such is unknown.

• In the anime version of these events, Moon was partnered with the female android Artemis who is not mentioned at all in the IDW material. She may not exist in this continuity or may be part of the Celestials, who knows.
