Death Armos

Death Armos are a type of Armos enemy found only in The Legend of Zelda: Majora's Mask. They look like huge stone statues of knights holding both a sword and a shield.

Majora's Mask
In The Legend of Zelda: Majora's Mask, they can be found exclusively in the Stone Tower Temple where they floats in the air and attacks by slamming down to the ground in an attempt to crush Link. They are almost invincible and the only thing able to hurt them is by shooting a Light Arrow at their red emblem which appears on their chest, the Death Armos will then flip upside-down. While inverted, it will continue to attack Link but, while doing so it will take damage. If Link wears the Stone Mask, it will ignore him.

"Death Armos, a temple guard... Look at that red mark on its chest! I know you've seen something like that before..."
