Budōra serves directly under Deathcobra as one of the Decepticon commander's three primary warriors. Alongside his comrades, he possesses the unique ability to merge into the powerful combiner Dinoforce, with Budōra specifically transforming into a robotic dragon.

He operates as a fiercely loyal and aggressive soldier, consistently following Deathcobra's orders in the hunt for energon and battles against the Autobots. Budōra exudes raw power and enthusiasm for battle, often displaying a reckless nature and acting as the trio's most openly combative member.

Within Dinoforce, Budōra forms the combined robot's upper body and head when merging with Goryu and Doryu. This formidable union represents their primary offensive capability against larger Autobot threats.

As events unfold, Budōra experiences internal conflict regarding his loyalty to Deathcobra. Instances of his commander's extreme methods or disregard for subordinates prompt Budōra to question Deathcobra's leadership, revealing a capacity for doubt and independent thought beneath his aggressive exterior.

This culminates when Deathcobra's actions cross a definitive line. Budōra, alongside Goryu and Doryu, consciously decides to defect from the Decepticon cause. They abandon Deathcobra and cease hostilities against the Autobots, marking a fundamental shift in allegiance driven by moral grounds. This defection signifies Budōra's most significant development, moving from unwavering loyalty to chosen defiance.

Following their defection, Budōra and his partners actively avoid further conflict, seeking a path separate from both Autobots and Decepticons. Their primary goal becomes self-preservation and finding a new existence away from the war.
