Hey, so we know that the armors from this game went on to be in Bomberman World. But something else I just noticed is that God Bomber himself survived the cancellation, albeit via a strange reincarnation.
The final boss of Bomberman World is God Header, a giant quadripedal robot with the head of a Bomberman. However, if you look at its head closely enough...
...you'll see that it has God Bomber's three-pronged head adornment!
The similarities don't stop there, either. According to the Japanese Wikipedia article for Bomberman World, the name of God Header's second form - the humanoid one - is actually God Bomber.
So yeah. The weirdness continues. I guess whoever came up with these characters was really pissed that the game got cancelled, and wanted them to be used somehow anyway. Maybe it was like this unused/used tile business in a couple of Zelda titles. :P
