Thundergirl Becomes the New Supergirl in Supergirl #19

Thundergirl has officially become the new Supergirl, according to a report by CBR.

The transition occurred in Supergirl #19, released on November 11, 2026, which established the character as the new Woman of Tomorrow and the leader of Super Force. This succession follows a period of instability for the mantle, triggered when Kara Zor-El lost her abilities after exposure to Gold Kryptonite, a substance that prevents the absorption of yellow sunlight.

The passing of the identity was not a hostile takeover but a sanctioned transition. Kara Zor-El gave her direct approval to her successor, telling her that she would “love it” to see her friend follow in her footsteps, CBR reported.

The genetic origins of a new hero

Unlike many figures who adopt a superhero persona, Thundergirl’s name was her designation at birth. She was not born through natural means but was created using the DNA of David “Boy Thunder” Sikela and the genetic makeup of the Kryptonian scientist Kimda.

Originally, she was part of a group of clones known as “Team Thunder” intended to serve as mindless, subordinate weapons. After the death of her siblings, she escaped Kimda’s control and eventually aligned herself with Kara Zor-El. While she was initially designed with limited potential due to her inability to absorb yellow sunlight, she has developed unique abilities including super strength, speed, durability, and a powerful sonic scream.

For the character, the alias represents more than just a new costume. Because of her origins as a manufactured weapon, she has expressed reluctance toward her given name, viewing the mantle of Supergirl as a chance for a fresh start.

DC characters change direction

The introduction of Thundergirl adds another layer to the complex history of the Supergirl identity. The mantle has seen several iterations beyond Kara Zor-El, including the shapeshifter Matrix, who assumed the role following Kara’s death during the 1985 Crisis on Infinite Earths storyline.

The current creative team behind this transition includes writer and artist Sophie Campbell, who has helmed the solo title since 2025. The issue features colors by Tamra Bonvillain and lettering by Becca Carey. While Thundergirl leads the Super Force, Kara Zor-El has returned to Stanhope College in hopes of regaining her lost powers.

This change reflects a trend in major intellectual property management: expanding legacy brands with new, diverse perspectives to maintain demographic engagement. As studios and publishers look to maximize the brand equity of established icons, the introduction of successors allows for continuous storytelling even when primary characters are sidelined by plot developments or power loss.

The Supergirl franchise continues to maintain a presence across different media formats, including the 2026 film directed by Craig Gillespie, which had a runtime of 108 minutes.

Supergirl #19 is currently available at comic book retailers.
