They are aggressive and territorial omnivores, mostly subsisting off of plants but not unknown to prey on other animals and even anthropoid Kryptonians. Their most distinctive trait is their head frill, which projects their thoughts and intentions.
A young Superboy happened upon a Thought-Beast that was abducted from Krypton by alien zoo-keepers before the explosion and reached Earth after smashing his cage open. Superboy was overpowered by the destructive monster and had to resort to lure it into another planet to get rid of it.
Several years later, an adult Superman was nearly killed by another Thought-Beast when he went back to the past to collect a fungus that only grew in the Scarlet Jungle.

Thought-Beasts also existed in this universe's Krypton as proved by a statement of Supergirl. As trying to bust open a barrier cast by the Enchantress, the Girl of Steel remarked it was "tougher than a Kryptonian Thought-Beast".
