Tabzaburo Tojima is a lifelong Kamen Rider fan boy who trained all his life to be a Kamen Rider, and is able to "henshin" (by going through the motions, and putting on a kid's mask) to manifest his hero's strength through sheer hyperfixation and obsession, so much so that he goes from defeating a bear barehanded when unmorphed to fighting actual monsters when morphed.

How would you build him? I'm thinking Zealot Barbarian \Watchers Paladin with the Charger Feat, and GWM if the DM allows you to reflavor a maul as his fists, to emulate how he hits like a freight train compared to his party, thoughts?
