Time Express Den-O was developed as part of a series of Heisei Rider Gashats by Genm Corp.. As part of CEO Kuroto Dan's ambition to gather the power of the legends preceeding his own Kamen Riders, they contributed to the completion of his Kamen Rider Battle: Ganbarizing. 「Part. I: Legend Rider Stage」
A manifestation of Kamen Rider Den-O (仮面ライダー電王, Kamen Raidā Den'ō) appeared as part of a gathering of the first seventeen Heisei Riders which empowered Genm as he performed the Ganbarizing Critical Strike, defeating the three doctor Riders with one Rider Kick. Returning to his lair, Dan announced to Parado, who had taken the guise of Dr. Pac-Man, that everything was proceeding according to plan as his assembly of Gashats was completed. 「Part.
