Armos

Armos Statues, also called Armos, are stone statues which have appeared in various games in the Legend of Zelda series, such as the Legend of Zelda, A Link to the Past, Ocarina of Time, Majora's Mask and The Wind Waker.

Killing Methods
The methods of killing one vary from game to game:


 * in LoZ, the best way was to just slash it with your sword.
 * In ALttP, they were most vulnerable to arrows, although slashing it with your sword worked as well.
 * In OoT as Young Link, and in MM, you could either throw a bomb to them or throw a Deku Nut, then slash with your sword.
 * As Adult Link in OoT, you could just cut it.
 * In TWW, you had to cut the red orb on its back, which was made a lot easier by stunning it with an arrow.
 * In PH, a single bomb will immobilise them, allowing you to push and pull them around like normal statues. Because of this, they are often found in groups, guarding switches.

!!!Note that in all 3D Zelda's, after killing one, they'd charge at you, and in the N64 Zelda's, they'd blow up after their charge!!!

Twilight Princess Armos
The Armos in Twilight Princess wield hammers and look very different those in from previous incarnations. They have a more tribal look, partly resembling the Moai statues on Easter Island. When animated, their facial features are clearly outlined by a glowing blue color. As in The Wind Waker, they are defeated by striking the weak spot on its rear. They are easiest to kill using the Mortal Draw skill, or by striking them with the Ball and Chain before they fully animate. They can also be killed with a bomb arrow before they wake up, if you hit the right spot.
