Jonathan Kent has not developed powers on Superman & Lois, but the show's third season is presenting another path for his character arc. From the beginning, one of the main focuses of Superman & Lois has been Clark Kent (Tyler Hoechlin) being a caring and devoted father to his teenage sons Jordan (Alex Garfin) and Jonathan (Jordan Elssas in seasons one and two, and Michael Bishop in season three). After revealing to Jordan and Jonathan that he is Superman, Clark's trials as a father multiply when Jordan develops Kryptonian powers that Clark must train him to harness.
