|This article is about a/an video game in Kamen Rider Ex-Aid.|
A double-sided Gashat derived from Mighty Brothers XX, the template that would become Knock Out Fighter 2 was one of four blank Gashats created by Kuroto Dan in his attempts to counter Cronus. Ultimately, he finished Doctor Mighty XX for this purpose.
Nazo Toki Labyrinth
Over a year later, Dan finished Knock Out Fighter 2 and incorporated it into his new game, Nazo Toki Labyrinth. Having been challenged to beat this game by Dan, both Emu Hojo and Parado entered the Game World together, finding themselves equipped with Gamer Drivers as well as a blank Gashat each.
Proceeding to complete a riddle seperately, the pair were faced by the Hatena Bugster. Though finding themselves incapable of using the blank Gashats, Emu and Parado's gratitude towards each other brought forth the Rider Gashat of Knock Out Fighter 2, which they used to respectively assume the form of Kamen Riders Ex-Aid and Para-DX Level 39. However, Hatena proved immune to their attacks, reminding them that force could not win a puzzle game. Remembering their previous riddles and their thanks, and noting the numbers printed all over Hatena, the two solve the third and final riddle by punching the numbers 3 ("san") and 9 ("kyu"), making up the wordplay Sankyū (さんきゅうー) (homonym for "Thank you"), with Hatena congratulating them for winning as he exploded.
