Your Villain OC is in a prison cell and sees her outside the cell

Edgyhead: *sitting in the cell with a nonchalant grin on his face *

Marie: *gasps* oh.my.god!!! I get to meet him!

Edgy: ...
Oh? Hello little one.

Marie: Haiiiii!!!

Edgy: what might you be doing here..?
You must be in the wrong place.

Marie: Nahhhh! I’m looking for a real guy to make me an apprentice!

Edgy: hmm.
I wasn't expecting a job interview.

Do you have anything to prove that you could be helpful for our cause?

Marie: well for one
*Marie suddenly disappears*

Edgy: impressive. However...*he grabs her by the shirt collar and lifts her up*
It takes more than that to fool me, and more importantly those who reject my knowledge.

*She isn’t there*

*Edgyhead grins with a mischievous expression*

Edgy: what else can you do, interesting child?

*She reappears with a bag of stolen goods ranging from crystal gems, a gold bar, and the code to all the cells*
Marie: Wanna start a riot?

Edgy: as fun as that would be, no.

I wish not to cause issues.

*he plucks the bag from her hands and it seems to disintegrate into red ruby-shaped particles*

Come now, my "apprentice".

*when the particles fade, Edgy is suddenly behind her, but the bars and cell are undamaged*

(Can I use a different one?

I don’t wanna use Nacla)

(Sure!)

Atlas: huh?

Marie: Heya! I heard you murdered someone! That musta been so fun!!!

Atlas: what?

Marie: C’mon, murder is so fun!!!

Atlas: n- no?

It isn’t-

Marie: Ugh you are so boring!

(Oh wait I thought is said my oc saw her in a cell)

Atlas: hey! I’m not boring >:|

Roswald: "?"

Bro literally said ÒwÓ

(I don't have a villain OC :( )

(What if you used Collector if he got imprisoned for all his crimes?)

*Interitus’s remains are kept in a glass case*

Interitus: …

Marie: and I know how to start that process!

Interitus: Tell me

Marie: Ooh you and that warlord go way back!?! You are so cool

Interitus: I’ve met him before. I offered to help with that military thing of his, the one that would bring order to the multiverse or something. A shame it failed.

Marie: Ohhhhhhh… the Inkversian Empire… wanna reinstall it!

Interitus: Sure. It’s better than sitting here like some dumb statue. And maybe we can brainwash that guy I showed you earlier to work for us.

Marie: Yippee!!! Let’s get started!!!

*Interitus’s head is placed on the body*

Interitus: Thank you for freeing me

Marie: Yeppers!

Interitus: So how are we supposed to go about this?

Marie: Well first *Ahem* We assassinate Bokun and Daihyo, then we take the throne by force, and then we make a totalitarian government!

Interitus: Great

Marie: Hey, Hey you! Wanna do some murdering!

Interitus: …anyone in specific?

Marie: Hmmmmm… how about, EVERYONE

Interitus: …that sounds pleasing. But first I want to eliminate a single target. *He displays a crude drawing of Supernova on his head-screen thing*

Marie: ooh! Yesss let’s get him!

Interitus: I will require a new body, however, as I consist of only a very fragile head and arm since I was destroyed

Marie: I know just the thing!
*Marie disappears*

Interitus: …this had better be good

*She returns with the body of EC*
Marie: how’s this?

Interitus: Although it’s weird using the body of an old friend, i’ll gladly take it, as anything’s better than sitting here all day

Xninix: who the hell are you?

Marie: I’m going to be your apprentice!

Xninix: really?

Marie: yeah! Unless another villain wants to make me their apprentice

Xninix: *walks up to the bars* and what can you do?

*She’s suddenly out of Xninix’s sight*

Xninix: huh?

Marie: soooooooooo… when do we start?
*Marie is in the jail cell with Xninix with the cell key*

Xninix: I like your vibe, we start as soon as you get these power bands off

*Marie gets the power bands off of Xninix*
Marie: Okay! So are we going to murder people, ooh, what about kidnapping!

Xninix: whatever you want after we get out of here

*Marie suddenly appears outside of the cell and unlocks it*

*alarm blaring*

Marie: Oh noes the Alarm! What ever shall we do!?! …I already killed all the guards

Xninix: not the security bots though

Marie: Really… ohhhhhhh those bots, I forgotttttttttt. Well this’ll be fun!

Xninix: no ot won't, those things are designed to kill people like me
