Benjamin Kirby "Ben" Tennyson: Ben is shown to be a cocky, immature boy, who is not above enjoying attention and enjoys making jokes even during fights. Though his immaturity makes a bad impression on some people, Ben is good-hearted, noble, and loyal, and his actions are motivated above all by a strong and sincere will to help and save others in need. He will stop at nothing to protect his family or anyone in danger whether human or alien.
