-
Major New Cast Members:
-
Darren Criss as Superboy (Kon-El): In a meta-nod to his previous DC voice work, Criss joins as the rebellious, ’90s-inspired clone. Showrunners have teased that this version of Superboy “embodies the tension between hope and fear.”
-
Max Mittelman as Cyborg Superman (Hank Henshaw): Mittelman (who voiced Lex Luthor in previous seasons) takes on the mantle of the cybernetic antagonist, who appears to be working closely with LexCorp.

My Adventures With Superman Season 3: Plot Details
The overarching theme for Season 3 is a reimagining of the “Reign of the Supermen” storyline. However, showrunner Jake Wyatt has noted that it is “less about the death of Superman and more about ‘What is a Superman?'”
Key narrative threads for Season 3 include:
-
Identity Crisis: While Clark is ready to “settle down” with Lois, Lois is facing a professional crisis. Having finally achieved her dream of becoming the Daily Planet’s star reporter, she fears that a stable relationship with a superhero might jeopardize her hard-earned status.
-
The Found Family Dynamics: Jimmy Olsen is navigating his new celebrity status as a “pro-alien journalist,” while simultaneously dealing with the awkward, high-stakes romantic interest of Supergirl.
-
The Alternate Supermen: The season features three “impostor” Supermen (Superboy, Cyborg Superman, and a third unrevealed alternate). Unlike the comics, these versions are being “adjusted” to be more relevant to the show’s core cast, testing Clark’s values against theirs.
-
The LexCorp Rise: With Lex Luthor now fully established, Season 3 will show the corporate side of the threat. Lex is using the arrival of the new Supermen to further his agenda of discrediting Clark and proving that Metropolis only needs “managed” heroes.
As of today, May 15, 2026, you can watch the first official trailer on YouTube or catch up on Seasons 1 and 2 on Max. With the premiere less than a month away, the countdown to the Reign is officially on.
