However, upon returning to his race, the alien convinced his leader that the Earth was ripe for conquering. They returned and re-entered the Colossus, which had been put up on display. The creature made its way to America, where it caused massive damage. There, Bob O'Bryan came up with a plan. While rampaging through the city, IT came across an even larger monster. The aliens inside saw a potentially greater shell for their plans, and left IT to enter the new monster. Shortly after, the second creature blew up, and it was revealed to be nothing more than a rigged construct to trap the aliens.
Months later, O'Bryan suffered a crippling accident when a sabotaged movie light fell on him, leaving his legs paralyzed. Wheelchair-bound, O'Bryan soon found out that he could now somehow bring IT to life with his own mind (though when this happened, O'Bryan's body would be useless). Using his new-found abilities, O'Bryan/IT defeated the mad Doctor Vault as well as an invading race of monsters led by Granitor.
Some time later, Dr. Vault succeeded in projecting his own mind into the Colossus, but his victory was short-lived, as IT was reduced to dust by The Incredible Hulk.
Much later, O'Bryan returned to making movies, where he created another, robotic, life-sized version of IT for a new film starring Simon Williams, the Avenger known as Wonder Man. A competing spfx-wizard took control of the new robot and sent it on a course of destruction through the movie lot before Williams and O'Bryan defeated it.
Not long after, Wonder Man's enemy Lotus somehow managed to not only cause the original IT's reformation, but took over O'Bryan's mind to control the creature. It once again encountered Wonder Man, this time accompanied by The Beast, and once again defeated.
It's current status is unknown, but presumed to be under the care of some police or government agency.
