He's one of the most gifted wizarding students of recent times, creating his own spell, being able to use the Russo family wand with amazing success, and being well viewed by adults and professors, both mortal and magical. In the show's finale, Justin keeps his wizard powers, replacing Professor Crumbs as the new Headmaster of WizTech.
