Panzer Dragoon

Panzer Dragoon (パンツァードラグーン) is a video game series developed by Sega, the first game being released for Sega Saturn in 1998. The games are primarily rail-shooter games, although the Panzer Dragoon Saga games are role-playing games, with the plotline being a hero or heroine with their dragon trying to fight against an evil empire in a post-apocalyptic world.

In the first Panzer Dragoon game, the dragon rider Keil Fluge rides the Blue Dragon to prevent the black dragon and its rider from arriving at the tower after the blue dragon's original rider was killed by it. The locale from this game appear in the Archie Comics crossover Worlds Unite.

When Sigma sends several Mavericks to different worlds, Burn Dinorex and Gigavolt Man-O-War attempt to set an Unity Engine in the Drowned Ruins, but met local resistance. When Rotor the Walrus and Bubble Man fought Burn Dinorex and harm him, the latter expressed anger at Gigavolt abandoning him out of cowardice (as the latter was fleeing from the blue dragon and his rider) and managed to activate the Unity Engine, to Rotor's horror. Keil Fluge and the Blue Dragon arrive in the area and destroy the two Mavericks. With Rotor's guidance, they are able to destroy the Unity Engine by weakening its shield with the acid Bubble Lead and having the dragon fire at it.
