Dinosorb is an evil brontosaurus who stomps and causes earthquakes.

The Meteorbs were egg-shaped living comet creatures that could transform from animal (or robot) form into a flying comet. There were five heroic and five evil Meteorbs.

The heroic Meteorbs were:

• Comet Cat
• Ty-Grrr
• Cometroid
• Astro Lion
• Tuskor

The evil Meteorbs were:

• Dinosorb
• Gore-illa
• Orbear
• Rhinorb
• Crocobite

According the to the Grayskull Wiki, Meteorbs were originally a Japanese toyline of transforming eggs from Bandai called Tamagoras and were released in the USA by Mattel as part of the Masters of the Universe toyline as transforming meteors.
Because the Masters of the Universe had by then passed its peak, the Meteorbs primarily appeared very rarely in the franchise’s fiction. Only two Meteorbs, Comet Cat and Dinosorb, appeared in a single episode of She-Ra, “Assault on the Hive”.

In the Marvel comics series the Meteorbs are portrayed as members of the Rock People. The Heroic Meteorbs appear among Stonedar and Rokkon. The Evil Meteorbs, led by Gore-illa, are renegade Rock People associated with Skeletor. They were portrayed more as pets than equal members of the Evil Warriors.
