here you go.
This is Onus. He's a mad scientist with his trademark fluffy hair and is known for cutting other ponies open with his trusty scapel.
I decided to make Onus a earth pony (which means he doesnt have wings or a horn) because he gives off that earth pony vibe. (and the fact that he has a suprising similar personality as pinkie pie which is also a earth pony)
Hope you like!
