TBH I kinda never planned that out, most likely would be twisted hybrids of Bomber-Cyborg-Badnik Men. I will make it clear Indigo that in my mind, considering how they aren't that different from each other let's be real, I kinda consider Bomberman a part of the Sonic universe, like some broad stokes version of events comparable to something like the Jetters anime, the various games like Super 1-5 and the two NES games, the TG16 games, just any of the games aside from maybe Act Zero and Bombergirl and the Super R games (tho the Act Zero Bombermen DO exist in my version alongside Smuggler and Fusell's plots) Basically in regards to SegaSonic canon, X, SATAM/Archie, Fleetway, AOSTH, Underground, OVA, Boom, etc Bomberman, Planet Bomber, Bomber Nebula, the Starry Sky Solar System and Star System Hurricana were always there we just never really see them as we focus on Sonic and co's adventures.
Hell one idea that evolved from having Dr Bad Boon from Super Monkey Ball as the one to have mentored and trained Eggman was Bagura/Buggler being Eggman's mentor and like the original idea with Super Monkey Ball characters co existing with Sonic and friends having Bad Boon and the bad guys from Banana Blitz be the secret leaders of the Eggman Empire, Eggman being a puppet leader. Bagura and the Robot Army/Buggler Army and maybe even Mujoe and the Hige Hige Bandits and Mechadoc were the true leaders of the Eggman Empire, having pulled the strings the entire time akin to Cobra-La in GI Joe and Eggman being a puppet leader, Metal going rogue in Heroes would be retconned as Bagura and co being fed up with Eggman's failures so they decide to reprogram Metal or secretly convince him to rally together the other robot copies and Badniks loyal to him and then start a cilvil war with those loyal to Eggman, Heroes would focus more on the inner war between those with Eggman and those with Metal and everybody else is caught in the middle.
