|“|| Class: Sergeant. Code name: Scorpion. He is a hero who repelled Black Viper's first invasion along with Mad Dog. Even so, he has never forgotten the memories of the ugly aliens and their horrible invasion plans. Scorpion is a quiet and intelligent man, and once he's on the battlefield, he turns into a ruthless, wild warrior more than anyone else. His attack is sharp like a scorpion's stab, and has sent numerous aliens to hell with no exception.
|~ Translation from the Japanese Contra 4 instruction booklet|
According to Contra 4ʼs partially re-written chronology of Contra, Scorpion first appeared in Operation C alongside his friend Mad Dog. (Note: Mad Dog and Scorpion were originally the American codenames for Bill Rizer and Lance Bean, respectively. Moreover, Scorpion's appearance was based on Lance Bean's in the arcade version of Super Contra.)
Although it is unclear whether it was Scorpion or Mad Dog in the role of the playable character, Operation C lets the player control a character in all-green clothes (like Mad Dog) and slightly tan skin (like Scorpion). He wears a black head-band and has somewhat cropped, blond hair (like Bill Rizer).
In Contra 4, Scorpion wears bluish-purple military pants with a red bandanna. He appears to be of Hispanic descent, as indicated by both his skin color and appearance in the manga.
