An Crystaline. Crystalines are like humans but with Crystals on their shoulders and green eyes, their crystals can change color to indicate the Crystaline's emotion like Yellow for Happiness, red for pissed off and etc, they live in Uranus.
Their crystals are part of their body.
They also have Crystal forests.
They hate apples so when they see the apples they hiss at the apple and back away.
Their diet is Black Crystals (cannibal) and uh.. Human organs.
(Don't joke about his home planet)
