Injured in a laboratory explosion, Basil Sandhurst created an exo-skeleton to house his crippled body. He designed the suit to feed off the cerebral energies of those around him and used his “slave discs” in an attempt to take over New York. He was defeated by Iron Man in what would be the first of many confrontations between the two. Most recently, Iron Man uncovered the Controller’s plan to influence the wealthy patrons of a clinic he had acquired.
The Controller wears an exoskeleton that grants him mobility, as well as superhuman strength (lifting 1000 pounds) and endurance. He uses “slave discs” to control others, up to several dozen at a time, draining cerebral energy to magnify him exoskeleton’s strength (to lift up to 50 tons and possibly more) and duplicate his victims’ abilities. He can psionically control “weak-willed” subjects even without discs. He flies via boot-jets and has employed image inducers, stun mists, and other technology as needed.
