Battle Arena (crossover RP)

"What nonsense are you on?"
He reflected on this. It was 1999, right?

Joker begrudgingly enters the arena. He's watching everyone else carefully, his eyes looking like they're glowing. He's using his Third Eye ability to gauge the power level of everyone. Most of them are either blue (weaker) or yellow (same strength) but some, mainly the stand users and Minato, are red, assuming Minato has the Universe Arcana. So if he has to fight those guys, he's going to have to rely heavily on strategy and not just brute strength to end the fight quickly.

Except the door doesn't lead to the arena, but to a room with a rather large screen taking up most of one of the walls.
Probably should have clarified that.

SELF-LEARNING AI. WE ADAPT OURSELVES BASED ON THE CONVERSATIONS WE HAVE.

"That's not a thing. AI can't even HAVE them yet in a way that isn't stupid! How would they LEARN at all??!"

Well, Joker is still looking at everyone anyways.

Aigis has arrived to hear Josuke going on about how A.I. can't learn. Obviously she doesn't agree with that fact, but she doesn't directly say anything.

"We're not even that advanced yet! And that's assuming Y2L is just a bunch if crap..."

"Excuse me, sir, but I was activated the year before the 'y2k' conspiracy was proven to be false. It's been over a decade since my activation, so I can assure you that this kind of technology is perfectly reasonable," Aigis speaks up, clarifying that they're not in the 1990s anymore.

Switch to Japanese. He recognizes the accent of a native when he hears one
"WHAAAAAAT?"

Aigis switches to Japanese herself, "It's not widely available technology, but it does exist."

If Joker looked at the lithe, almost fae scientist, he'd see not blue or yellow or red, but a pitch black aura.

Huh. Weird.

The two extended screens both move back to their original spots on the wall. All of them, sans the large screen in the room, all change to read the same message.
PLEASE STEP INTO THE ROOM.

Vanessa walks through, still humming a waltz to herself.

The scientist follows.

Pink lad enters the room.

Minato is indeed red.  Which is not good.  He enters the room as well.

Shadow Labrys begrudgingly enters the room.  She doesn’t look very happy about this.  

Basically all of my characters enter.

"None of you going to resist? Is everyone scared of a little bullet or something?????"

"I doubt bullets are the only things that at its disposal. It may be best to 'participate'." Aigis isn't actually planning on doing so, but using participation as a guise to cover up research into why they're here may be the best way to figure out how to stop this.

The scientist seems largely disinterested, and Vanessa doesn't see much choice. This place would kill her either way.

"It better tell me. I can take a bullet, that isn't even remotely threatening. Obviously it doesn't know who I am."

All of my characters enter, Hamuko and Yu are both yellow, although Yu is on the lower end of that range, while Hamuko is on the higher.

Neo has been following Roman this whole time.

Rabbit girl also heads into the room, keeping a safe distance away from Ghiaccio and Karkat.
