John Doe is the central protagonist of unORDINARY. John currently attends Wellston Private High School as a 3rd year student and the 2nd ranked student, but repeatedly got bullied at 1st for claiming that he was powerless. After Arlo's betrayal, during his best friend, Seraphina's suspension, he revealed his true power by ripping apart Wellston's hierarchy under the alias of Joker, donning an infamous black mask. After a fallout with his best friend, he is enraged and takes over as the school's tyrannical King alongside Zeke.
