Great Wyvern is the dragon-based mecha of the Rescue Fire team. It is a fusion Rescue Combination Vehicle of Super Fire Dragon and Super Jet Falcon, taking all the components of both and rearranging them into its configuration. Its Final Rescue is Infinite Thunder (インフィニットサンダー Infinitto Sandā), where the dragon charges up a powerful surge of electricity and then fires it from its mouth at the target, followed by a Wyvern Attack (ワイバーンアタック Waibān Atakku), where Dash-1 channels power from all the Rescue Vehicles and is then fired in an electrically charged ball of energy to destroy the target.
