since the two games are made by different companies they will never officially be in the same universe but there enough Devil May Cry references in Bayonetta that it wouldn't be hard to make them seem like the same universe. and thats the point of this thread to explain the differences and figure out how the games would fit together.
Devil May Cry references in Bayonetta and how they would be explained if the two games where in the same universe:
1.there is a charicter named Antonio Redgrave in bayonetta; Dante used the alias Tony Redgrave.
Explanation: Dante met Antonio and decided to use his name. or since there are some hints Sparda used the same alias(L&O have the same inscription as E&I" For Tony Redgrave By .45 Art Warks") the explanation could be that Sparda was the one that met Antonio(which makes more since because if DMC1 takes place around the same time as Bayonetta Dante whould have been a little kid when Antonio died.)
2. both games have a charicter named Enzo who is an informant (and seem to be the same person)
Explanation: Enzo knows both Dante and Bayonetta.
3. it is mentioned that there are devil hunters living in the same area as Bayonetta, Rodin and Enzo. ("the Dump")
Explanation
ante and Bayonetta might live in the same area(it seems likely if they both know Enzo)
4.Phantasmaraneae is very similer to Phantom.
Explanation: they could be the same Demon under different names or simply relatives.
(there are probably a few more references i can't remember.)
so anyone have any opinions on this. references i missed. alternate explanations etc.
and there are a few more things that would need to be explained but i don't want to talk about everything at once.(at this point most threads don't last very long so i want to try to make this one last a while)
