a small monkey oftenly mistaken for a little person or a human in general.there is only one left in the world. the ONYX looks like a stud. although of its hairy feartures most humans cant tell with just the naked eye. Usually when scientists try to uncovert he mysteries of the ONYX, they get hairy balls thrown at them.
*An example for onyx would be when you get raped by your grandmother and the nightmares that come with it*

Get the Onyxmug. A talented, passionate, strong and caring person. They are very considerate as they’re always looking for ways to uplift others and lend a helping hand. For how much they have to offer, they need to treat themself kinder for how much B.S. they endure. They’re deserving of the world, but the world doesn’t always deserve an Onyx.
Did you see Onyx at the show last night? They absolutely killed their part!
Right?! And acting’s just one of their many talents!

Get the Onyxmug. A very hyper dog. Annoying but loyal. He is spiteful and will take a literal shat in the floor while starring you in the eyes. Don't get an onyx.
