Cyborg 009 (1966 film)
In the area surrounding the base, 009, 006, and 007 fight off against a spider-shaped mecha, while 003 is abducted and put on an operating table to be re-programmed against the other cyborgs. As the others enter the base and fight off against the soldiers, they find the newly evil 003 waiting for them and attempting to shoot them. 009 then discovers that the true leader of Black Ghost is a brain inside a machine, and shoots at it, causing the brainwashing on 003 to be broken. But with the base set to explode, they must escape.
