"You're a greedy one, aren't you, President Johnny Maxima?"
―Masamune Dan[src]

Johnny Maxima accepted Masamune Dan's request for Machina Vision to co-operate with Genm Corp.'s worldwide release project for Kamen Rider Chronicle, on the condition that he receive a single Gamer Driver. Destiny Reboot!

"The ending for Kamen Rider Chronicle is near...Mister Masamune!"
―Johnny Maxima, witnessing the endgame of Kamen Rider Chronicle[src]

He's shown taking Graphite's Gashacon Bugvisor after his destruction. He witnesses the arrival of Gamedeus and comments how Kamen Rider Chronicle is entering its final stage. Reset Game!


Not much to be known about Johnny's traits, except that he is a CEO whose god complex is already shown before the involvement of Bugster virus. Although self-proclaimed as a fan of Japanese cultures, including ninja, Kiriya pointed on his poor research of mistaking the kanji for "Negi" ( welsh onion) as "Shinobi" ( "ninja").
