Blaze and Volt face their ultimate test as Neon City's legendary guardians. Every villain they've ever defeated-Helix, Shadow & Pulse, Vortex, and Origin-returns in a final, coordinated alliance to destroy their unbreakable bond and seize control of the city's power grid. As blackouts spread, truth-serum chaos erupts, void rifts swallow civilians, and energy drains threaten total collapse, the heroes must protect their home while confronting the cost of being icons: the fear of losing each other forever and the question of life after legend.
