Bloody Brad

The TX-11 Arnold is the codename of a series of "cyberoids" develed by Dr. Madnar.

Story
When Dr. Madnar was taken captive by Outer Heaven, he was forced to use his robotic technology to develop two cyberoid units. They're resistant to virtually all sorts of firepowers, with some exception. During Operation Intrude N313, Solid Snake fought against two TX-11 units and managed to destroy them using an RPG-7 provided to him by Jennifer.
