Death is a villain who want's to destroy everything in the universe and doesn't care who does even if it's he's friend. He thinks everyone is a pest and will destroy everyone who get's in his way!
He has lot's of equipment including a ray gun, death ray, and a size modifier.
He has chaos powers and ninja powers. He can also fuse with Nazo to turn into Deazo who's very powerful. As Deazo, he is invincible to anything except people on his stage of power.
His weakness is his intelligence. He's not that clever and can be easily out smarted. His power barely makes up for this.
