Grademon (Fusion)

Grademon was former Tactimon's subordinate who was defeated by Shoutmon X4. After he was defeated, Taiki wished him a good digimon. Soon Grademon became a good digimon who betrayed Tactimon and helped Taiki escape Sword Zone by destroying the antena. Unfortunately, Xros Heart and Blue Flare lost all their code crowns because of Bagramon's Choujigen Storm attack. Shoutmon, Taiki Kudou, Zenjirou Tsurugi, and Akari Hinomoto were vanished by the storm and went to the human world.
