Drum Bunker Dragon, also known as Fang Slade Terrestrial XIII, hails from Dragon World as the son of Drum Bunker Dragon Father, former leader of the Drum Clan. He inherits his father's legacy, rising to become chief of the clan. His partnership with Gao Mikado starts turbulently, defined by disagreements and mutual frustration, especially Gao's stated preference for Dragon Knights over dragons—a view Drum vehemently opposes. This early phase features frequent clashes over minor issues, like food deprivation, showcasing Drum's hotheaded, stubborn, and somewhat selfish nature. He remains consistently sensitive to perceived slights against dragons or his clan's status, reflecting deep pride in his heritage. Driven by insecurities about measuring up to his father's legacy and proving his worth, Drum develops an inferiority complex. This motivates him to leave Gao after the ABC Cup and train across multiple worlds. His journey unlocks new forms and abilities tied to each world: Dragowizard Magician Drum in Magic World and Brave Drum in Dungeon World. These transformations grant Gao access to diverse decks and Buddyfight strategies, marking Drum's commitment to self-improvement and transcending his initial limitations. Returning from training, Drum exhibits significant personal growth, maturing into a more selfless and loyal companion. He fully embraces Gao as his true buddy, offering unwavering support even when broader circumstances turn against Gao, such as during the Gaen Cup fallout. His dedication deepens as he accepts the role of Fifth Omni Dragon Lord, joining the Omni Lords to confront the existential threat posed by the monstrous Yamigedo to Earth, demonstrating his willingness to shoulder immense responsibility. After resolving the Yamigedo crisis, Drum steps down as Gao's active buddy to serve as the new chief of the Drum Clan in Dragon World. He later becomes a father to ten children. Despite his responsibilities, he maintains his connection to Gao. He participates in the GGG Cup tournament during "X: All-Star Fight," reuniting with Gao after an invitation from Guru Bumbuku. There, Drum, alongside Dragon of the Sun and Bal Dragon, aids Gao in securing victory. Post-tournament, Drum returns to Dragon World but commits to future visits, acknowledging his enduring bond with Gao, who relocates to the United States. Physically, Drum possesses a red body with an orange underbelly, flowing spiky gold hair, and distinctive gold armor featuring a ruby jewel on the cuirass. His attire includes a dark red tattered cape secured by a brown belt and a three-clawed wrist plate on his left arm, consistent with the typical appearance of the Drum Clan. Within the Buddyfight card game, Drum Bunker Dragon functions as a monster card with a size of 2, 5000 power, a critical value of 3, and 5000 defense. His abilities include a call cost requiring payment of 1 gauge and placing the top card of the deck into his soul, alongside the Soulguard ability. He belongs to the Dragon World, specifically under the Armordragon and Red Dragon attributes. The card has seen multiple releases across various sets and maintains unlimited legal status in English, Japanese, and Thai formats; flavor text varies by printing, reflecting aspects like his determination to surpass his father.
