Iron Arm

Iron Arm (アイアンアーム) is the boss of stages 3 and 5 from The Ninja Warriors.

Details
Iron Arm appears as a tall, muscular man wearing a iron plate mail, helmet and brown pants. He carries a lengthy kusarigama (chain and sickle weapon) with a spiked ball in one end which he uses to attack, swinging the spiked ball above his head and throwing it to hit the player. If the player gets too close he will instead attack with the sickle to push the player back. He is immune to shurikens thrown by the player.

A weaker version of him appears during the final stage, while a stronger variant appears as the last enemy the player faces right before Banglar.
