thoughtsY/N POV
Y/N: SAMUEL!!!!!Samuel: goodbye doomslayer.
I yelled in raged as I was teleported to an unknown location. When the portal opened, I was standing in a forest.
Y/N:Where am I?
I then heard a low growl, followed by howling.
Y/N:Sound like wolves.
Suddenly a large wolf-like creature the size of a hell knight jumped out of the bushes.
Y/N: What are you?
It slashed me, tearing through 1% of my armor. I pulled out my shotgun and blasted it. The beast staggered giving me enough time to grab it's head and smash it against my knee.
Y/N: Wow, that was easy.
Then I heard a roar, and a bear the size of a baron of hell emerged from the bushes, and was followed by several wolf creatures.
I cracked my neckY/N:Good, I needed to let some anger out.

3rd person POV
RWBY:So why did you call us here Ozpin.Ozpin:There has been an unidentified energy signature in the emerald forest. I would like you to investigate.
RWBY:Yes sir.
Time skip
As team RWBY exited the bull head they saw a man in an armored suit fight what was left of a horde of Grimm. It looks as if he had started out with 200, and now all that was left was a lone Ursa. The ground was coated with the bodies of fallen beowulfs.
The man ran toward the Ursa, moving as fast as Ruby. He jumped over it, using his thrust boots to gain extra height. He landed behind it, and pulled a shotgun out of no where. He blasted the Ursa twice, then ripped off its arm and beat the Ursa with it. The Ursa collapsed, adding one more number to the man's kill count. The man then whipped around, pointing his shotgun at the shocked huntresses.Y/N: Who are you and what do want.
Ruby: We're team RWBY, and we were sent on a mission to find a mysterious energy source that showed up in this forest.
Y/N: That was me. I was teleported here from Mars by Dr. Samuel Hayden.
Ruby: Teleported?
Weiss: Mars?
Blake: Dr Samuel Hayden?
Yang: You?
Weiss: But dust doesn't work outside of the atmosphere? How were you on Mars?
Blake: Who is Dr Samuel Hayden.
Yang: It was you?
Ruby: Teleported?
Y/N: Uuugh. Alright, I guess I'll have to start from the beginning.
Y/N told them the story, but left out the demons.
Yang: Wow, Samuel Hayden is a prick.
Y/N: Correct.
Ruby: Yang, what's a prick?
Yang: I'll tell you when you're older Ruby.
Weiss: So you come from a dimension with advanced technology that allowed humanity to get to Mars?
Y/N: Yep.
Blake: And this advanced technology was what teleported you here?
Y/N: Yes.
Ruby: Do they have cookies where you come from?
Y/N: Yu- wait what?
Ruby: Do you have cookies where you come from?
Y/N: Yes, but what does that have to do with anything?
Ruby: Just curious.
Y/N: Anyway, now that I've answered your questions, can you answer mine?
RWBY: We'll try.
Y/N: Where am I, what are those *points at grimm* , and do you know what Argent energy is?
Weiss: Your on Remnant, in the kingdom of Vale, in the Emerald forest. Those things a Grimm, large creature who like to kill people, destroy things, and make everybody's life's suck. They are attracted to negative feelings.
As for 'Argent energy', we'll have to ask Ozpin about that.Y/N: Who is this 'Ozpin'?
Weiss: The headmaster of Beacon Academy, the school we attend. He might be able to answer your questions
Y/N: Alright, now that that's all cleared up, could you take me to this 'Beacon Academy'?
