Bomberman was created by Mitsumori and Ein

Mitsumori didn’t become Bagura but Bagura/Buggler was a man formerly known as Frank R Bagura who was turned into a Bomber Cyborg alongside the Dastardlies by General Ganzu

Pretty/Karaoke is a separate person from Lisa

She is also not Bomberman’s sister

The other coloured Bombermen are either not brothers or were created in some random factory alongside any other Bomberperson we see in the series

Earth still exists alongside Planet Bomber and Bomber Nebula

Bomberman is set in a ambiguous future timeframe of our current time

Wario Blast isn’t canon but GB is canon

Elements from Act Zero in the form of the Act Zero Bombermen and Smuggler and Fusell of the Super R games exist despite the games themselves being non canon,
Farmer Bomber is a Bomber based on the original MSX BM design
Smuggler plot from SBR1 and plot of SBR2 happened VERY DIFFERENTLY from canon

Some elements of Jetters and Land and B Bakugaiden also exist here

Basically anything from the Hudson Era is canon to me but stuff like Bombergirl? Hell no!
