Rift to National City: A Dragons and Heroes Crossover

A bizarre, glowing spatial anomaly in the Fissure sucks Tom Kullersen and his dragon, Thunder, out of the Hidden World and drops them directly into the skies of National City. Confused, separated from the rest of the Dragon Riders, and targeted by the Department of Extranormal Operations (DEO), Tom must navigate a world of superheroes, aliens, and advanced technology. When Supergirl mistakes Thunder for an escaped alien beast, Tom has to quickly prove his dragon is a partner, not a threat. Together with Team Supergirl, they must find a way to stabilize the unstable dimensional rift before malicious forces from both universes exploit the gateway.
