Unexpected Crossover [Male Reader x Series]

[This story has been abandoned at the end of volume 1, sorry for those who enjoyed reading.]

A story set in the RWBY universe with BioShock, Undertale, Doki Doki Literature Club and Portal mixed in, meaning characters and locations will be in the RWBY universe, changing some events in the past and of course changing the story of RWBY as well.

It's my second full on story and I decided on doing this since I love all the series and while they're not at all similar, I think I did a good job on blending the elements together to make a unique yet familiar world of Remnant while also setting up enough plot elements for the story to advance in an almost natural way.

Disclaimer: Other universes could be included in random points of the story, some are planned (naturally inserted into the story not the universe itself, there's not about to be tears in reality here), others are not (only if it required minor edits to incorporate). I am currently not taking any votes for rather or not an universe should be included, mainly because it would be too wild and my lack of information on the hypothetical universe voted in could lead to errors on my end.

That or the universe would be too overpowered for RWBY, an example being Dragonball, literally any saiyan (even babies) in Oozaru would be building level at least, far above most RWBY cast. Another reason could be not meshing well, an example being Mario (Sadly no Bowsette waifu lads) since Goombas, Koopa Troopas, Chain Chomps, all those things would just be hard to incorporate without tearing holes in reality to wrap them here, give a terrible reason why they're only now being discovered against all odds or simply not interact with the universe as a whole.
