The Rubies refer to you as Defect and Goofball.

Appearance: You are a Ruby, obviously, with your gem on your back. Your hair isn't a sqaure afro like other Rubies, it's more short and spikey, but still black. You have a light gap between your front teeth. Clothing can look how you like.

Weapon: Now I'm not sure if weapons actually work like this in Steven Universe, but your weapons are spider like legs that come from your gem. Kinda like Spider-Man's iron suit.

Personality: You're kind of a goofball, if the nickname didn't give that away, and you want to make everyone happy.

Powers: Super speed and super strength. Being a defect has it's perks.

Other: Sometimes too much information or something really difficult to decide makes you "break".
