"The Blue Bomber" can be used in the game editor as an alternate sprite swap for Mario by unlocking him through his amiibo for Super Smash Bros.
Since the stages are redesigned in the Mario environment, the gameplay would naturally follow the Mario style, and the absence of lesser enemies Robot Masters were compensated for by makeshift baddies from Goombas, Koopa Troopas, Hammer Bros., etc.
