Tubbo is a ram hybrid, having goat ears, tail and legs that bend forward slightly. Technoblade was ordered to execute Tubbo by launching a firework at him. Half of Tubbos face is disfigured, the corner of his mouth was torn, his eye is all white and red and droopy, his scars look like melted skin and his left goat ear is all tattered and ripped. 

Tubbo had brown hair and one green eyes that he still has full vision in. He’s definitely traumatized from the explosion.
