Luckily for us, Bomberman's hardly a fandom to be plagued with either stupid slash or bad lemon fics. Let us celebrate!
You'd be surprised. I've seen (Only the cover!!) of a Yaoi, and I only realised sometime after that one of the characters had a Jetters badge. And there was a sphere above his head. And he had very Bomberman'ish clothing.
...Well yeah, human version of Bomberman in Yaoi. Mind you that's the only trace of Bomberman in Yaoi I've seen.
