Lt. Steel is the head of SACT which stands for Special Alien Capture Team. He has had many encounters with Kevin, who was posing as the Omnitrix aliens at the time. He is very authoritative, and his men fear him enough to know not to go against any direct order from him. At first he is very suspicious of Ben and his family, but later allows them to come and go as they please. Ben ends up saving him from Kevin while in alien 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. Later, during the Forever Knights' attempt to remove the Omnitrix by trapping Ben in a perfect dream world, a false Lt. Steel arrives and tries to convince Ben that the real Gwen and Grandpa Max are Limax. When the illusion is exposed, Steel transforms into Enoch.
