Armor is an enemy that first appeared in Ninja-Kun.
Their thick armor is impenetrable. The only way to expose their weakness is to land on their head and stun them, or jump into them from below. The later of the two methods is easier since it sets you up to kill stunned Armors quickly. Be sure to dispatch them immediately after stunning them, or they will get back up and regain their invulnerability. Patience is the key to defeating a stage full of Armors. Concentrate on one at a time and time your falls so that you land on their heads consistently. Armors are capable of firing many fast arrows from their bows in rapid succession.
