SPOILER WARNING: This article contains major spoilers for "Crisis on Infinite Earths, Part 1," the first installment of this year's Arrowverse crossover.


It's official: Jonathan Kent, aka Superboy, has made his Arrowverse debut.

"Crisis on Infinite Earths, Part 1" checked in on Clark Kent and Lois Lane during their stay in Argo City, a floating remnant of Krypton where its native inhabitants do not have superpowers. The couple traveled there to see out Lois' pregnancy in the safest way possible, and it seems to have worked, since Clark was introduced as he changed his son's diaper.

"Jonathan really has your eyes, huh?" Lois mused, confirming that the child is indeed the DC Rebirth character.

"I'll take it, so long as he has your everything else," Clark replied with a smile. When he suggested they have two children, she made it sound like that wasn't in the cards, meaning Jon will likely be an only child.

Unbeknownst to the happy family, a wave of antimatter was headed towards Argo City. As soon as Supergirl found out, she contacted Clark just as the sky turned red. Without his powers, Clark could do nothing to save them, but his aunt Alura had a plan. She led them to the city's only escape pod, with the intention of sending Jon to Earth to be saved.

Like his parents before him, Clark placed his only son into the escape pod. "We'll always be with you, Jonathan," he whispered, as Lois held their son's hand.

"We will never leave you, even in the face of our deaths," she added.

"We love you," he said, and they sent him off into space as Argo City was destroyed in the blast. Everyone was killed in the process, with a notable exception.

Lyla Michaels' Harbinger intervened and rescued Lois and Clark. She brought them to Earth to help the Monitor fight off the antimatter wave. There, they learned Jonathan's pod was sucked into a wormhole, which sent him to several different Earths. With a little help from White Canary and Brainiac-5, Lois recovered him while Superman defended Earth-38. She found him safe and sound on Earth-16, in the care of an elderly Oliver Queen, and brought him back to Earth-1. There, they reunited with Clark and bore witness to Oliver Queen's death.

Fortunately for Superman fans, this family will likely survive the coming Crisis. After all, The CW is developing Superman and Lois Lane, with Tyler Hoechlin and Elizabeth Tulloch reprising the title roles. The series will follow "the world's most famous super hero and comics' most famous journalist deal with all the stress, pressures and complexities that come with being working parents in today's society," which suggests Jon will be a key component of the show.

In the comics, of course, Lois and Clark have a son named Jonathan Kent, who has inherited the Superboy moniker. Jon is a rather new character, having debuted in 2015's Convergence: Superman #2 by Dan Jurgens, but has risen in popularity in DC Rebirth titles like Super Sons. He was recently aged up from 10 years old to 17 years old, a transformation that came with his very own Kryptonian armor. In the Arrowverse so far, Jon remains in an infant.

"Crisis on Infinite Earths" begins Sunday, Dec. 8 at 8 p.m. ET/PT on Supergirl, then continues in Batwoman on Monday, Dec. 9 at 8 p.m. ET/PT and in The Flash on Tuesday, Dec. 10 at 8 p.m. ET/PT. After the winter hiatus, the crossover will conclude on Tuesday, Jan. 14 in Arrow at 8 p.m. ET/PT and in DC's Legends of Tomorrow at 9 p.m. ET/PT.
