When Zora Vi-Lar, aka Black Flame, went on the warpath, Kara Zor-El risked everything to warn Lesla-Lar. And when Kara didn't return from the miniature city of Kandor, Conner Kent and Lena Luthor ventured inside without knowing if they could escape. While Zora gave Conner a beating, Lena and Lesla helped Kara reclaim her Supergirl status. And even if Zora gave Lena her freeze breath, Lesla became Luminary once again.
Can Kara and Lesla free Kandor from Zora's tyranny? And can Kara and her friends breathe life into the recently rediscovered Argo City? Let’s leap into Supergirl #15 and see!
Story
Finding her miniaturized home city inside Kandor should have been a dream come true for Kara Zor-El. Yet its inhabitants were long dead, and the city lay in ruins. Still, Lesla-Lar led Kara to a chamber where she learned that a Sun Crystal existed on Earth. But before she can reclaim this aspect of her Kryptonian heritage, Kara must quell Zora’s rebellion in Kandor. By using Thundergirl’s solar reservoir, Lesla has become Luminary again. But Zora still wears the Yellow Ring of Kandor. And in her anger, the Black Flame seems intent on incinerating everyone and everything.
Lena Luthor remains frozen in place. But in Supergirl #15, Kara leads Conner Kent, Thundergirl, and Lesla-Lar in a battle to save Kandor. While each member of her team demonstrates their strengths, Kara soon realizes that she must tackle Zora alone. Like Lesla, Zora disagreed with the Science Council’s leadership. But while Lesla poured her energies into scientific invention, Zora embraced anarchy. Kara recognizes that Zora has let her anger at the Science Council's rule consume her. So, she lures Zora away from the others to give the Black Flame the power she craves.
While Sophie Campbell’s story focuses on Kara and Zora’s battle for power, it also reveals the result of the Science Council’s repression. Bry-zan and Lesla-Lar’s parents sought to preserve their Kryptonian heritage. But they used their political power to prevent their society from evolving. With their miniaturized city in rubble, the people of Kandor must decide what their future will look like. And as Kara contemplates her own future, she wants to help Kandor rebuild. But first, she must prevent Zora from destroying the last vestiges of Kryptonian society in Supergirl #15.
Art
As Supergirl and Luminary battle the Black Flame in the cracked and crumbling chamber, Zora lashes out at Superboy as he struggles to rise behind his frozen friend. When Thundergirl finds her voice, Zora trails smoke as she flees Argo, while sunlight streams around Supergirl and her friends as they pursue her. The fibers Rust excretes from its Super-Substance body cover the wrecked buildings of Kandor. As Zora uses her heat vision to incinerate Lesla’s solar reservoir, Kara falls, trailing yellow smoke from the device that allowed her to fly.
As Sophie Campbell portrays Kara Zor-El’s fast-paced defense of Kandor and her friends, Tamra Bonvillain adorns Supergirl #15 with an appealing palette. Inside the bottle city, Rust's orange Super-Substance strung between the broken buildings evoked the majesty of desert hoodoos. Yet from inside the Fortress of Solitude, the strands of orange filling the bottle reveal the depths of Zora’s avarice. While Lesla and Bry-Zan both wear indigo, they disagree on how to best care for their fellow citizens. Despite their green attire, Thundergirl and Lesla’s parents seem unsure how to move forward. Still, although broken, the sapphire city remains a home that the Kandorians love. Still, the yellow on Supergirl's new uniform echoes the air inside Kandor, while the blue links with Earth's atmosphere.
Becca Carey fills white dialogue balloons with black uppercase letters that grow bold for intonation and shrink for lowered voices. Zora’s balloons deform as she lashes out at everyone around her. Sound effects enhance the high-flying battle, while text in black balloons recalls a villain who threatened Midvale. Zora may have stripped Thundergirl of her solar reservoir. Still, Thundergirl surprises herself when she summons blue letters that help her become the hero her city needs. Thanks to DC Comics for sharing this story with us.
Final Thoughts
Kara Zor-El didn’t think she could mentor Lesla-Lar. When Lesla had to return to Kandor, Kara thought she had failed her. Disappointments and betrayals may have marred Kara and Lesla’s relationship. But when it really matters, Lesla inspires Kara to forge a new future and helps her fight for others in Supergirl #15.
