You and Team RWBY had gathered around Sci-Twi as she was about to show off her newest creation. 

Sci-Twi: Okay, guys, so I've managed to create something brand new! This generator! 

Ruby: Wow! That looks so cool! Uh ... what is it? 

Sci-Twi: A dimensional generator. I wanted to try and see if I could go the extra mile and make something that was like the Gameboy. Which is what the 3DS originally was. 

Yang: So, it's a portal then? 

Sci-Twi: Well, sort of. Kind of. Either way, I'm ready to test it out. 

Blake: And we're here in case something bad happens? 

Sci-Twi: That and an audience. 

(Y/N): Well, either way, this should be interesting. 

Sci-Twi: Okay! Here goes! 

Sci-Twi activated the machine and opened up a big rift! 

Sci-Twi: YES! YES! I think we got something! 

A green-like aura was coming from it. 

Weiss: I think it's getting a bit too strong! 

Blake: Something is coming. 

Ruby: What, can you hear it? 

Blake: Yes! 

???: HAHAHAHAHAHAHAHAHAHA! AT LAST, I'M FREE! 

A spirit with shades and a suit appeared!

Yang: Uh ... Sci-Twi, did you just release an evil ghost?! 

Sci-Twi: Wait ... it's like I made a portal into a ghost area ... or is it Ghost Zone? 

???: Child, you have freed me from my prison! And now, I, Technus, master of all things technical and mechanical, can start my reign! EVERYTHING SHALL BOW TO MY WILL! 

(Y/N): Well- 

You got out the Poltergust. 

(Y/N): Time to start busting! 

Technus: Oh no, you don't! I'm not going into a- 

Ruby: OVERSOUL: SPIRIT CLEAVER! 

Ruby stopped the ghost with her big spiritual scythe and then- 

(Y/N): Time to clean up your act! 

Technus: THIS ISN'T OVER! I SHALL RETURN! AND THEN I, TECHNUS, MASTER OF- 

(Y/N): OH SHUT THE HELL UP! 

He was sucked into the Poltergust! 

Weiss: Okay, we have to find out more about this before we open it again. 

Sci-Twi: Yes, good idea. That was unexpected. 

Little did you guys know, someone had picked up the presence of a ghost. 

???: So, someone made another Ghost Zone Portal? Yes, how very interesting. This could be just what I need.
