Stage: stage 3
The boss of stage 3 wears a long black coat with a purple lining, a matching purple tie, and dark sunglasses. He has black hair in a square cut and attacks with a long sword.
The same sprite is used for several other enemies in the same stage, but their ties and coat linings are grey rather than purple.
The sword-wielding boss's appearance is based upon the antagonist Koji Sato, played by Yusaku Matsuda, in the 1989 Ridley Scott film Black Rain.
