The teaser opens with low, desolate cityscapes before a distant sonic boom heralds her arrival. Kara’s silhouette cuts through storm clouds, landing with purpose as citizens look skyward, burdened by fear and longing for a protector. Brief flashes show her navigating moral conflict and a world that has changed since last she donned the cape. With hushed whispers of legacy and a heartbeat-thumping score, the trailer hints at a Supergirl forged not just from strength, but from belief — her journey a canvas of resilience and defiance in the face of rising threats.
