Beest is a distant planet inhabited by a race of anthropomorphic animals known as the Beastformers. Beest used to be a relatively peaceful planet, with dissenters few and generally quiet about their dissatisfaction with the planet's then-rulers, until the Transformers came to stir things up as they so often do, with each faction joining with their appropriate Beastformer counterparts.
- English/Malay dub name: Pisto
While out in space, the Autobots came into contact with two refugee Beastformers who had come to seek help. The Decepticons invaded planet Beest and helped the enemy forces of Alligatoron take control. The Autobots then assisted the good Beastformers, led by White Leo, to free planet Beest from Decepticon tyranny.
Once again, the Decepticons teamed up with Alligatoron to take over planet Beest. The good Battle Beasts (now being aided by the wild jungle boy, Kane) sent for help from the Autobots, who arrived to help defeat the Decepticons and Alligatoron.
Laser Beasts manga
The planet Beest was originally a wasteland, scoured by intense heat with no water or breathable atmosphere. When the Three Wise Men crash-landed there, they immediately moved underground and developed the vast subterranean empire of the Laser Beasts. 20014 years later, after hostilities between the Laser Beasts began to develop, a group of peaceful Laser Beasts traveled to the surface of Beest for the first time ever. They found the planet had changed drastically since the Three Wise Men founded their civilization, having become a jungle abundant with life. Meanwhile, a great flood wiped out the subterranean empire, leaving the remaining Laser Beasts to journey to the surface as well.
Encountering the Beastformers for the first time, the two Beast lifeforms immediately clashed in an all-out war which would decide the fate of planet Beest.

- The only official English interpretation of the planet's name appeared in the Dreamwave Summer Special, where it was referred to as "Planet Beest". Previously, the planet was simply spelled "Planet Beast" in most English episode guides written by fans, as no English version of the name had ever been officially released at the time.
