Starscream – Who was sadly dropped when he was a sparkling – has onlyntold his brothers (Thundercracker and Skywarp) about his colorblindness. He's embarrassed by it, and feels self conscious about his little disability. He is defensive, cocky, and sometimes can be a smartass, but never around Megatron. He is protective of his brothers, and will do anything to make sure they're safe. He also loves and cares deeply about his human companion, willing to die for them if it meant keeping them safe.
