Jonathan Steel was the young and ambitious Assistant to 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 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 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 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.

Lt. Commander of Enforcer
Selfish, greedy, arrogant, cruel, and lazy, Steel desires power and influence above all else. While not quite as psychotic or sadistic as Dark Kat or Dr. Viper, Steel can be uncaring and unsympathetic toward other people's suffering, and only cares about himself above all else.
