From the Metal Gear Wiki
Bloody Brad (ブラッディ・ブラッド, Buraddi Buraddo?) was the codename of the TX-11 series of "cyberoids" developed by Dr. Madnar. 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 firepower. During Operation Intrude N313, Solid Snake fought against two TX-11 units simultaneously and managed to destroy them only by using an RPG-7 provided to him by Jennifer. It is rumored that they were created using prototype Snatcher technology.
[edit] Trivia
- The Brads were called Arnold(s) in the original MSX2 version, a direct reference to actor Arnold Schwarzenegger for his role in The Terminator.
