The Arbiter is the main antagonist of Power Rangers: Unworthy. Claiming to be the first Power Ranger, he has hunted rangers across the Multiverse, taking their power coins as he views all other power rangers to be unworthy. He is sociopathic and self-righteous, as a result of how his own actions led to loss and destruction and instead of accepting the blame that was his own he displaced his guilt and remorse by blaming the Zordon of his own dimension, claiming Zordon gave powers to innocent people and beguiled them with foolish notions of becoming heroes, only for them to fall fighting evil forces. Though Zordon tried to assure this disturbed ranger into believing otherwise, he spitefully chose to destroy Zordon despite the risks in doing so. After slaying Zordon, this fallen power ranger was exposed to intense power from the Morphing Grid, resulting in his madness becoming visible in the form of his charred and damaged black suit. Narcissitcially believing the Morphing Grid to have chosen him, he took on the name of 'the Arbiter', with the delusion that it was now his duty to travel throughout the Multiverse to strip power rangers of their power coins regardless of who they are and what good they did. Due to his immense powers and relentless drive to carry out his mission, he has defeated and even killed many power rangers despite many of them fighting valiantly but ultimately being no match for the Arbiter. The Arbiter is insane and cannot be reasoned with. He will not compromise his deluded madness, and once he sets his sights on a power ranger he will never stop hunting them until he has taken their power coin or killed them.
