Worlds Collide: Sky of Steel

During a routine scouting mission near the Edge, a violent Singetail blast accidentally ignites a hidden cache of volatile Changewing acid and unstable Titan-wing Gronckle iron. The resulting explosion tears a massive rift in the fabric of space-time. Hiccup and Toothless are pulled into the vortex, blacking out instantly. They wake up plummeting through a sky filled with glass towers, strange metal birds, and zero Night Furies. Trapped in a high-tech metropolis known as National City, Hiccup must navigate an alien world of superheroes, rogue aliens, and advanced technology. To find a way home, he must team up with Supergirl and the heroes of the Tower while keeping Toothless safe from a government agency that views dragons as an extraterrestrial threat.
