Grademon

Grademon is a Warrior Digimon and a carrier of the X Antibody whose name is derived from "grade" and whose design is derived from the medieval knight. It wields a pair of swords, and is called the "Golden Meteor" due to the way it cuts into the vanguard with dauntless courage. When it uses its "Souken Gradalpha" (双剣グレイダルファー Souken Gureidarufā?, lit. "Twin Swords Gradalpha") along with its twin-sword style, it brings a godly speed to those techniques, but due to the cursed swords it becomes impossible for it to control itself, and it can't fight and still retain its sanity. Although its overall power is, after all, inferior, its sword techniques surpass even the Holy Knight Crusadermon, of the "Royal Knights", and it is said that its royal blue mantle is proof of the honor that was bestowed for its achievements over many battles.

Digimon Fusion
Grademon was the leader of the Bagra Army's force to invade the Sword Zone. When Lord Bagra first attempted to conquer the Digital World, He corrupted Grademon into the violet Evil Grademon.

From that point, Grademon serves as the commander of the Sword Zone branch, under Tactimon. He tries to obtain the Sword Zone's Code Crown by becoming the best swordsman in the Zone, but he is defeated by Shoutmon X4, while the Fusion Fighters annihilate the rest of his force. When Mikey Kudo obtains the Sword Zone's Code Crown, the last unclaimed fragment, Grademon is purified along with the other corrupted Digimon from Zones that Mikey controls. Though Grademon initially rejects the purification, he returns to protect Mikey from Tactimon. Grateful that Mikey has allowed him one chance to do good, Grademon sacrifices himself to destroy the Disruptor Tower that sealed all transportation to and from the Sword Zone.

After rescuing the Fusion Fighters United Army, WarGreymon and Examon explain how Lord Bagra corrupted Grademon, among others. Later, with the power of the true Code Crown, Grademon is revived along with all of the other killed Digimon to help defeat the Bagra Army in the final battle. He joins in the largest DigiFuse to become Shoutmon X7F Superior Mode, who defeats MegaDarknessBagramon. After the battle, he returns to the Digital World with the rest of the Digimon.
