The Arc of Ooo (a RWBY & ADVENTURE TIME story)

CHAPTER 1: meeting Prismo.

(AT PRISMO'S PLACE) 

After the Fionna & Cake universe became authorized to be a part of the multiverse and that scarab was sentenced to become Prismo's roommate after he tried to SLAUGHTER!!!!! the Fionna & Cake universe, it was all going well with Prismo as he was chilling out on his laptop, or at least he was until he and Scarab, who was sweeping the floors, got an alert from Prismo's new remote control

Prismo: huh.

He questioned as he reached to his remote and touched the button, which brought up the words ''Icon in Danger''

Prismo: an icon? I haven't gotten an alert like that in... forever.

Scarab: (sigh) let's just see who & where this icon is.

He said as Prismo clicked the remote again and it showed the planet remnant, which surprised Both prismo & scarab

Scarab: Remnant? I haven't been to that world since those sibling gods left that place.

Prismo: and don't forget that they restarted humanity all over again on Remnant, along with creating the faunas as well. But that raises one question... which one of them is the Icon?

He questioned as he went through each human & faunas such as Blake's parents, Tai Xiao Long, Raven Branwen, Salem, but then he found who the icon, who was hiding in a cave with a fearful look on his face as the Grimm passed the cave and this icon is... Jaune Arc

Jaune: (on screen) (breathes out) the Grimm are gone (sigh) that's good.

Scarab: (wide eyes) Oh Crap!!!

Prismo: (wide eyes) the boss said that he knew this day would come.

Then the two stare at each other, nodded, and prismo pressed the remote as that button press teleported Jaune from the Cave and inside of the Time room

Jaune: what the heck? How did I get here? ....am I dead?

He questioned, and then...

Prismo: nope, you're not dead.

He said as Jaune looked up and sees Prismo smiling at him while scarab just waved bluntly

Jaune: (wide eyes) what the are you two? And where am I?

He asked while having wide anime eyes

Prismo: this is my forced roommate, Scrabby.

Scarab: (mutters) nobody calls me that anymore.

Prismo: and I'm... Prismo the Wish master.

Jaune: ...THAT TELLS ME NOTHING!!!

He yelled as prismo rolled his eyes in annoyance

Prismo: well, as wish master, I grant... wishes.

Jaune: you mean like a genie or something?

He asked as prismo shrugged his shoulders

Prismo: something like that, and sometimes those wishes require me to create new wish-altered realities. Lots of wishes, lots of worlds and in the time room, which is what you're standing in, is the perch from which scarab & myself keep our eyes on the growing multiverse.

He explained as Jaune began to understand it

Jaune: ...ok, well what about Remnant?

Scarab: well, let's just say that your world is the oldest of them all, it was created by me and prismo's boss. But our boss couldn't keep watching over Remnant any longer so, he gave that duty to the Brother Gods, and they pretended to be the ones that created your world, until they, kind of, took that responsibility too far, which led to them being betrayed by humanity, them wiping humanity out, started life all over before leaving Remnant for good.

Prismo: and before you say anything about you being betrayed by your ''friends & family' over your fake transcripts to enter Beacon Academy, we already know about it.

He said, making Jaune's eyes widen in shock

Jaune: how do you know about that?!

Prismo: because our boss told me and scarab that we'd bring you here and send you to a new home once this day came.

He explained as jaune was shocked that these two guardians knew about what he did, then he shook his head to regain focus

Jaune: ok, but where are you going to send me to? 

(IN MARCELINE'S CAVE-HOUSE, OOO) 

We see jaune being teleported inside of Marceline's house in the living room, which jaune finds it to be comfortable until he sees Marceline, who is sleeping while having tears flowing down from her closed eyes

Jaune: (blushes & thinks) oh man, she's hot. But why is she sad?
