The other day I was browsing Hudson's Bomberman Master game list and checking out some of the game specific pages again.
In particular, I happened on the page for the GBA double feature pack that features both Bomberman 1 and 2 for the NES:

Now if you check out the pictures, there is one that has a major oddity in it:

Two white bombers, apparently appearing in the game's storymode.
Weird, isn't it? I don't remember anything like that happening when I played the game.
It probably is just a glitch, but did a second Bomberman show up to anyone here?
Even stranger, according to Ragey Hudson completely cut out of this port the battle mode, so it definitely couldn't be that (not that it looks like it, with the Ballom and the setting that was not the game's battle mode arena but eh...)
