Steel is a minor antagonist in SWAT Kats: The Radical Squadron. Voiced by Hal Rayle, he is Commander Feral's second-in-command, serving as Lieutenant Commander of the Enforcers. Young and ambitious, he constantly seeks to usurp Feral's position as commander, though he lacks the necessary patience.
Steel is a young cat of average build, with orange fur and blond hair neatly trimmed. He wears an outfit similar to Feral's, consisting of a light gray greatcoat with blue cuffs and gold trimming, along with a white dress shirt, blue suit and blue pants held by a black belt with a golden buckle, and knee-length black boots.
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 in Season 1 Episode 3
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 Steel.
Feral ended up as Madkat's third victim of revenge, and Steele quickly took over as commander yet again, ignoring poor Katzmer and making him wait all day despite nagging from the an 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 in Season 1 Episode 12.
