Chimeras are a grab bag of monsterous mutations. No two chimeras are exactly alike. They take features resembling great cats, bulls, rams, dragons, raptors, and serpents into various combinations.
Chimeras have leonine or crocodillian like bodies. They may have between one to four heads, counting thoes with a serpent for a tail. Most of them are winged and can fly.
They have a high animal intelligence, likeky due to the brain power of their multiple heads working in consert. Unlike hydras however who are one mind in multiple heads, chimeras are somewhat unstable, even schitsophrenic, because of the differences in their multiple brains. This makes it very difficult to tame or train them even if raised from birth.
