Lieutenant Commander Steel is a minor antagonist in SWAT Kats: The Radical Squadron. He was voiced by Hal Rayle.
Steel was the young and ambitious second-in-command of Commander Feral. Steel had his sights set on Feral's job, but he had neither the patience to wait for his turn nor the experience needed for such an important position. During Dark Kat's plot to nuke Megakat City, Feral tried to sneak aboard the Doomsday Express, but got himself captured in the process. Rather than try to rescue him, the selfish Steel instead took over as commander, but Feral was saved by the SWAT Kats and Dark Kat defeated, and it is unknown if Steel was punished or not despite seeming to have a change of heart and come looking for Feral.
He still held the position of Lieutenant Commander during the appearance of Madkat. Katzmer arrived at Enforcer Headquarters to report the robbery, but because Feral was in the middle of running off to save Mayor Manx, the old shopkeeper was instructed to see Lt. Steel. Feral ended up as Madkat's third victim of revenge, and Steel quickly took over as commander yet again, ignoring poor Katzmer and making him wait all day despite nagging from the Enforcer Sergeant. He did little if anything to prevent Madkat from taking hostage Deputy Mayor Briggs, and tried to blame Enforcer Headquarters' destruction on the SWAT Kats. But after being set free by the vigilantes, Feral told Steel to shut up.
What became of him after this is unknown.
- In his first appearance in The Wrath of Dark Kat, Steel insists his name is spelled "with two Es," implying it is "Steel." However, the nameplate on his desk in Enter the Madkat says "Steele."
- He does not reappear in season two. While some fans think Feral's niece Felina replaced him, her rank is only lieutenant, not lieutenant commander. But whether Steel is still in the Enforcers or if another lieutenant commander has taken his place is unknown.
