Timestream has often recruited cyborgs and other warriors from various temporal periods and differing timelines to serve as his agents.
Time Control and Manipulation: Timestream can manipulate temporal energy for a variety of effects. He can travel forward or backward in time, and into alternate realities, as well as into the timestream itself, at will. He can also infuse others with temporal energies as well, transforming them into past, future, and even alternate future versions of themselves. He can shift himself partially out of reality to allow attacks to pass through him, and he can heal himself from injuries by shifting his own body back or forward in time.
Weapons: Timestream has access to a large arsenal of advanced weaponry from his own and other futures. He tends to carry the Technosword, an energy sword, although its exact abilities are unknown.
Henry Akai was one of the head technicians for the Nth Command, a subsidiary of the Brand Corporation, which was itself a subsidiary of the Roxxon Oil Company. Akai's work culminated in Operation: Purge. One day, several units of Nth Commandos had made synchronized attacks on the headquarters of the Fantastic Four, Avengers, X-Men, and Defenders. Using Nth Projectors, all of these adventurers were displaced to alternate realities where they would soon die. Also, individual meta-human adventurers had been hunted down and similarly teleported. Roxxon, with no meta-humans to worry about, attacked the U.S. government, intending a quick coup d'etat.
Akai was threatened with assassination by his future self, Timestream, who thought that by doing so he could undo the blunders of his youth. He was defended by a time-travelling group that included Deathlok the Demolisher, Michael Collins (the Deathlok of Earth-616), and the future version of his fellow Nth Commander, Godwulf. These men successfully protected the younger Akai, allowing him to full fill his destiny as he was caught within a power surge of the Nth Generator, which granted him the temporal powers to become Timestream.
