Thundergirl becomes Supergirl in DC’s issue #19 after Gold Kryptonite sidelines Kara. Here’s what the change means and what readers should watch next.
Thundergirl becomes Supergirl — Thundergirl becomes the new Supergirl in DC Comics’ Supergirl #19, taking on the mantle after Kara Zor-El loses access to her powers.
Key takeaways
- Thundergirl becomes Supergirl in issue #19 after Kara can no longer use her powers.
- Kara’s loss follows exposure to Gold Kryptonite, which prompts a search for someone else to carry the identity.
- Thundergirl was engineered as a weapon, but later escaped control and chose a new purpose as a hero.
What changed: Thundergirl takes the Supergirl mantle
DC Comics has given the Supergirl identity to Thundergirl, a character whose path to the role differs sharply from Kara Zor-El’s. The change appears in Supergirl #19, which the supplied source says was released on November 11, 2026, and includes a direct nod to the new bearer from Kara.
Kara’s circumstances set the transition in motion. After exposure to Gold Kryptonite, she could no longer channel her powers, leaving the question of who might take up the mantle open.
Matrix and Nightflame were among the characters competing for the role, but Thundergirl ultimately received it. The issue is written and illustrated by Sophie Campbell, with lettering by Becca Carey and colors by Tamra Bonvillain.
The decision is not simply a matter of choosing a replacement while Kara is powerless. Thundergirl has her own history, abilities and reasons for wanting a different identity, giving the handoff a character-specific dimension.
Why it matters: Supergirl becomes a story about choosing an identity
For readers following DC’s Supergirl stories, this development changes who carries a familiar heroic name while keeping Kara central to the transition. The mantle passes through a relationship between the two characters rather than appearing as an unrelated title change.
Thundergirl’s background makes the choice especially meaningful. The source describes her as a clone created in Kandor from the DNA of David “Boy Thunder” Sikela and Kryptonian scientist Kimda, and says she was initially controlled as part of Team Thunder. Her move into the Supergirl role follows a history in which other people defined her purpose.
That history also gives her wish to leave her old identity behind a clear basis. The source says she feels uncomfortable with the alias she was given and does not want to remain associated with it; taking the Supergirl name offers a new identity tied to her life as an independent hero.
Analysis: The change matters most to readers invested in how comic-book legacies are passed on. Thundergirl’s selection links that familiar mantle to a character who has had to break away from control and establish her own purpose, while the source does not say whether the change will be permanent.
Who is affected: Kara, Thundergirl and Supergirl readers
Kara is affected first because Gold Kryptonite has left her unable to channel her powers. The supplied account does not say that she has lost the Supergirl name forever, so readers should distinguish the immediate change from a permanent retirement.
Thundergirl now has the mantle, but her abilities have not followed the usual Kryptonian route. Because she was created rather than born a pure Kryptonian, she initially could not absorb power naturally from yellow sunlight and relied on cybernetic solar implants that imitated Kryptonian powers.
Over time, she developed self-sustained abilities, becoming more durable, stronger and faster, according to the source. She can fly and use a signature sonic scream, giving the new Supergirl a defined power set that differs from the familiar account of Kara.
Readers exploring other current comic-book developments may also find context in TechnoRapper’s coverage of Daredevil #700 and Matt Murdock’s turning points. That story is separate from DC’s Supergirl transition, but it offers another example of a comic issue revisiting a hero’s history.
What to watch next: how long the new status quo lasts
The next question is how DC develops the relationship between Kara and Thundergirl after the handoff. The source confirms Kara’s nod and Thundergirl’s selection, but it does not describe what the characters do together after issue #19.
Readers can also watch for how Thundergirl’s history shapes her use of the name. She was made as a weapon, lost her Team Thunder “siblings,” freed herself from Kimda’s control and became an independent hero before working with Supergirl. Those events provide a basis for future conflict or growth, though the supplied material does not confirm a particular storyline.
Her powers are another point to follow. The source says she moved from dependence on cybernetic solar implants to self-sustained abilities, but it does not explain the limits of those abilities or how they may compare with Kara’s in future issues.
