In the Original Series, Steel has blonde hair that was in a buzzcut, with a long scar on his face. He wore a black shirt with two straps, carrying guns in the pockets. In addition, he wore a belt with pouches. He had grey pants.
Lieutenant Steel is very authoritative, and his men fear him enough to know not to go against any direct order from him. He is very tough and serious in his job.
Prior to his first appearance, Lieutenant Steel had had many encounters with Kevin, who was posing as the Omnitrix aliens at the time. Steel and the Special Alien Containment Team were chasing after Kevin, as well as the Omnitrix aliens, across the country.
He first appeared in Framed. When the chase was brought back to Ben, after Kevin stranded Diamondhead holding the cash that the SACT and Steel were led to believe Diamondhead was the thief. Although Ben eventually transformed back into a human without the SACT seeing it, the sight of the Omnitrix on his wrist caught Steel's interest, and he proceeded to follow the Tennysons with the utmost suspicion that they were harboring the aliens. Outmatched when he tried to confront Kevin in his mutant form, he ended up being saved by Four Arms. Steel returned the favor by first having his troops fire on Kevin, saving Four Arms's life, and by letting him go free instead of having his men attempt to take him down too, thus clearing Ben's name from which Kevin had tarnished.
He reappeared in a dream in Perfect Day during the Forever Knights' attempt to remove the Omnitrix by trapping Ben in a perfect dream world, in which a false Steel arrived and tried to convince Ben that the real Gwen and Max were Limax sent by Vilgax. When the illusion was exposed by a flaw Gwen points out in Vilgax's personality, Steel transformed into Enoch.
In Animo Crackers, Steel was in charge of escorting the A.R.C. project. He and his forces were attacked by both Animos and their mutant rides enroute; then he received a call from Ben Tennyson. He mentioned that he hadn't heard from Ben in years.
