TV Special
Description
Bizon Gerafil stands as the primary antagonist across the Buddy Complex narrative. His past includes a childhood spent as Hina Yumihara's next-door neighbor and classmate at the same academy, fostering a deep, unreciprocated devotion to her.

Initially a loyal First Lieutenant, Junior Grade, and second-in-command of the Trident's Valiancer Unit for the Zogilia Republic, Bizon pilots the swift Nebiros Valiancer. He later transitions to the Coupling Valiancer Nergal and ultimately commands the massive Stand Alone Mode Karkinos, which emits jamming signals to disrupt enemy Coupling systems. His tactical skill and piloting prowess make him a dangerous adversary, capable of challenging veterans like Lee Conrad and Dio Weinberg.

Bizon's personality undergoes significant change. Beginning as a calm, confident soldier devoted to Zogilia and showing care for comrades, his all-consuming obsession with Hina and fierce rivalry with Aoba Watase trigger a descent into volatility. Recognizing Aoba as the Luxon's pilot fixates Bizon on destroying him, often recklessly endangering Hina during battles. This hatred intensifies as Hina grows closer to Aoba. Following a temporal displacement, Bizon arrives in 2014 attempting to kill Aoba, only to be stopped by Hina. Damage to his Valiancer leads to a failed self-destruction attempt, pulling him, Aoba, and Hina into a time vortex.

In the Final Chapter's altered timeline, Bizon adopts the identity Evgeni Kedar, orchestrates a coup, and becomes Chairman of Zogilia's Provisional Supreme Council. Confined to a wheelchair and masked, his psyche deteriorates into vengeful madness. He commissions the Karkinos, prioritizing the destruction of Aoba and Hina at any cost, sacrificing allies and initiating a suicide attack aimed at devastating Earth. Aoba recognizes Evgeni's actions stem from protecting his pride and ego. His final confrontation ends with the destruction of his mecha by Aoba, Dio, and Hina, thwarting Earth's annihilation.

In spin-off media like *Buddy Complex: Coupling in the Battlefield* and *Super Robot Wars X*, Bizon confronts revelations about his future as Evgeni. This prompts temporary alliances with protagonists in efforts to prevent his descent into villainy, exploring an alternative path where he strives to defy his dark fate.
