radiation emitters and his "encephalo-ray", which plunges its victims into a deathlike coma. The latter ray also allows Ultron to mesmerize and outright mind-control his victims, or implant subliminal hypnotic commands within their minds to be enacted at a later time. Ultron's outer shell is usually composed of Adamantium, rendering it almost totally impervious to damage; however, his internal mechanisms are generally less durable and more easily damaged. Ultron's Adamantium forms have proven vulnerable to molecular rearrangement devices and the metal-destabilizing ore known as Savage Land Vibranium ("anti-metal"). Some Ultron models feature tractor beams and energy absorption capabilities. Most Ultrons are powered by a small internal nuclear furnace, and incorporate a "program transmitter" which can beam part or all of Ultron's programming into remote locations such as computers or alternate robotic bodies. Ultron can often control other machines remotely even if he has not transplanted his consciousness into them. One recent Ultron model developed hive-mind technology, allowing him to animate and control hundreds of alternate Ultron bodies at the same time, becoming a robotic one-man army. Ultron is one of the foremost robotics experts on Earth. less
