Motivation: To be left alone by other ponies in ponyvill and Canterlot.

Roleplay : To be a powerful earth pony.

Skills: His spiky-quilled tail and it's nightmare poison were the reasons he was placed in Tartarus. Fanning it like a peacock tail, the quilled fur could shoot out these quills at an enemy. The quills secrete a poison that causes nightmares, hallucination, and insomnia. Luckly, he can control his tail's poison to a degree. The quills are immune to magic and cannot be removed from a pony by 'force'.
He is also good at hoof-to-hoof combat.

Personality: Has a certain contempt for Twilight's group of friends; he refers to them constantly with derisive nicknames such as "the nerd herd", "the pony dweeb patrol", or "the geek pony squad".
Plus, he is fairly condescending and scathing to everypony, with the exception of foals and colts.
he has a sense of superiority and a sense of arrogance, making it extremely difficult to anypony to earn his respect. He does not bow to anypony, even Celestia. but will show respect to princess Luna.

Quotes: 'Spare me the friendship nonsence, Twilight!'

'Get out of my way, AppleJacky!'

'You're in no position to be telling me what to do, Rainbow Dash!'

'That's getting old, you foals!'

'canterlot is an out-dated joke. But then so are all the ponies who live their, so I guess that fits.'

'Is that the best you ponies can do?'

'Why don't you pony geeks look for an opponent you can actually beat. Like an infant, or a rabbit …'

'That's right Fluttershy! Fall to the ground like the whimpering foal that you are!'

'Don't waste my time.'

'I don't need help from the likes of you ponies.'

'Friendship is for the weak, little ponies.'

'Haven't you realized by now that teamwork's not my thing, pony geeks?'

'When are you ponies going to stop giving that friendship speech?'

'Don't blame me because you came from a family of losers, Applejack.'

'Stop saving equestria and get a hobby, you geeks!'

'Oh, I'd forgotten how prissy your princess Celestia can be, ponies. It's really quite pathetic.'

tl;dr;Basically this OC is a emo mary sue who picks fights with MLP characters because he is a d--- just for the sake of being a d---
