Chaar

Chaar (in Japan, Jarr) is a fictional planet in the Transformers series

Transformers: Generation 1

The Planet Chaar debuted in The Five Faces of Darkness (Part 1) in the third season of The Transformers. It is a small, burned-out husk of a planet located in distant space, easily mistaken for a smudge on a map. It apparently supported a civilization at one point, as abandoned structures are seen on the surface. The surface is desolate and lacks vegetation, but some native lifeforms exist, including an enormous spider.

Following Unicron’s attack on Cybertron in 2005, the Autobots reclaimed Cybertron, and the surviving Decepticons, without their leader, Galvatron, were forced to withdraw to Chaar, where they struggled to eke out an existence, relying on the meager amounts of energon that could be acquired from other worlds. Eventually, Cyclonus set out to find Galvatron but, in his absence, the Quintessons supplied the Decepticons with energon in return for their assistance in launching an attack against the Autobots. With the return of Galvatron, the alliance was restructured, but the ensuing attack on Cybertron ended in failure, resulting in the Decepticons again returning to Chaar, which served as their base of operations for the remainder of the series.

After Earth and Cybertron, Chaar appeared in more episodes of the original television series than any other planet.

Transformers: Cybertron

Chaar was also mentioned in Transformers: Cybertron, but as an asteroid belt, not a planet.
