In the Original Series, Steel had 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.
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 appears in Framed. When the chase is brought back to Ben after Kevin strands Ben (as Diamondhead) holding the cash that the SACT and Steel are led to believe Diamondhead was the thief. Steel proceeds to follow Ben and team with the utmost suspicion that they are harboring the aliens. He ends up saving Ben (as Four Arms) from Kevin while in his mutant form. Steel returns the favor by first having his troops fire on Kevin, saving Ben's life, and by letting him go free instead of having his men attempt to take him down, too.
He reappears 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 arrives and tries to convince Ben that the real Gwen and Grandpa Max are Limax sent by Vilgax. When the illusion is exposed by a flaw Gwen points out in Vilgax's personality, Steel transforms into Enoch.
In Animo Crackers, Steel is in charge of escorting the A.R.C. project, when he's attacked by both Animos, and their mutant rides; then he receives a call from Ben Tennyson. He mentions that he hasn't heard from Ben in years since an incident with Kevin.
