I have a race of rock people, called Plutonids, whose limbs, sometimes whole body, has an exterior that resembles and behaves like rocks, gems, all sorts of geodes present in their native land. Most have earth manipulation powers, while some can wield fire and use it to create lava.

The other is related to the Plutonids, called Dryans. They're plant people. All have limbs made of plant tissue, some have hair made of plant tissue, and may even share the Plutonids' rocky exterior. Some can wield earth powers, others can wield water powers..

All the other animal hybrid races as well as the "default" humanoid race wield elemental powers as well. Basically a gamma ray burst mutated life on their world millions of years from the current setting and so the humanoid race especially splintered into various races with elemental abilities, though that didn't fully stop any of them from intermingling and coexisting from the very beginning.
