Ogre Arm

The Ogre Arms are the massive, close-quarter weapons of Strength. Unlike any other weapons, the Ogre Arms are always attached to Strength.

History
The Ogre Arms were first seen being utilised in Episode 4 of the anime, albeit for non-lethal purposes. Strength used them to drag the body of the beheaded Chariot and hurl the pieces off a clif.

The Ogre Arms were seen in combat for the first time in Episode 6, used against Insane Black Rock Shooter. They are frighteningly powerful melee weapons, and were able to severely damage even the powerful Insane Black Rock Shooter. They were used flexibly (e.g. blocking a sword stroke by grabbing the blade) and in concert with Strength's scorpion-like tail. Despite their sheer power and bulk, they do not hamper Strength's speed at all.

In Episode 07, it's shown that it can be used for long-ranged attacks because of its machine guns attached to the fingers of the weapon, which also had great firepower.

Other Versions
In the GAME, XNFE uses a pair of mechanical arms similar to this that lets her fire lasers and functions like a remote control to control her robotic minions.
