The CW's upcoming Superman & Lois has found the couple's Super Sons, as Jordan Elsass and Alexander Garfin join the Arrowverse series as the couple's young sons.

Deadline reports Elsass will play Jonathan, who is described as "clean-cut, modest and kind-hearted, with an aw-shucks attitude that somehow doesn’t seem dated." Garfin will portray Jordan, who is "wildly intelligent, but his mercurial temperament and social anxiety limits his interactions with people, and consequently, Jordan prefers to spend most of his free time alone, playing video games." The site also reports that Jonathan and Jordan are believed to be twins.

Last season's Arrowverse crossover, titled "Elseworlds," revealed Superman (Tyler Hoechlin) and Lois Lane (Elizabeth Tulloch) were going to have a baby. Young Jon was shown briefly in the beginning of this season's "Crisis on Infinite Earths" crossover. However, Jon, Clark Kent and Lois were among those killed when the multiverse was wiped out by the Anti-Monitor. When the Arrowverse heroes defeated the Anti-Monitor and Oliver Queen made his heroic sacrifice, the multiverse was restored, with many of the Earths combined into one.

Of course, this wasn't the only change made to the Arrowverse, as the effects of "Crisis" have also left Superman and Lois with two teenage boys.

The CW's Superman & Lois stars Tyler Hoechlin and Elizabeth Tulloch. The new Arrowverse series is expected to debut during the 2020-21 TV season.
