Changing the reality in RWBY (RWBY harem x OP male oc)

"I will change the fate of this world."

Toad Skywalker was appalled. He just finished watching RWBY volume 8 and was enraged by the outcome of team RWBY.

Toad: what the hell man! I can't believe that the writers would do something like this!

Marik: dude calm down. I don't like how it ended either.
Toad: if I was in RWBY, I would do things as they were supposed to like preventing Summer from dying and the fall of beacon and most importantly preventing Cinder from killing Pyrrha!
Marik: *to himself* oh boy here we go.
Toad: are you even listening Marik?
Marik: yes I am dude. And you probably would've prevented Yang from losing her arm.
Toad: exactly! She's my 2nd favorite RWBY character!
Marik: I know and your most favorite is Blake. And how exactly do we go into the series? Ask the gods of light and darkness to take us there and ask them to give us godly powers?
Toad: bruh that's not a bad idea.
Marik: me and my big mouth.
Toad: and you know what will make the series even better? If Asuna, Pyra and Mythra was in the show with us and I would be the driver of the aegis.
Marik: that's cool and all but I get the feeling that they would become yanderes for you.
Toad: hey I'm cool with that. At least they wouldn't cheat on me for those ugly bastards.
Marik: you gotta stop looking at those NTR images on R34.

Timeskip.

Toad and Marik find themselves in front of Summer's grave. Toad walked up to the grave and then.....

???: huh? What happened? Last thing I remember is I was being surrounded by grimm and then I died.
