Duplidemon's Betrayel

If you don't know about Duplidemon's previous plan, Duplidemon was freezing all of the Mushroom Kingdom in time and sending the places to his own realm. He was getting close to absorbing the entire Mushroom Kingdom, when eight heroes of prophecy defeated his minions, scaled his tower, and sealed him away in another dimension, leaving his minions trapped in the realm he was creating.
Now Nega Koopa and Nega Guy reveal that all along they were planning on betraying Duplidemon, and now with himm gone it's their turn to try and do what Duplidemon failed. But what is their plan? And will Duplidemon ever return?

I learned from my last plot and their is no prphecy, so I can't exclude people, I just never expected so many people would want to be in my plot.

And I want Kotonoha back! T_T

What are you talking about?

Spam much, Karasz?

Nega Guy has revealed his plan, transforming everyone into their nega forms so they can serve him.

Is Zaffira going to be a hero or victim?

You choose, if you want her to continue to help with your plot, then just have her flee.

Nah, I'd rather have her in this one.

If you ever continue your plot, this will wait, so she can be in both.

RC malfunctioning is a part of my plot, I guess.

Like I said, I'd rather have her in this. Who are the other heroes?

Anybody who wants to be in it.

I have an Idea: What if she slowly becomes Nega or something like that because of the Nega Troopa she absorbed?

That will work.

If Karasz is in it and the heroes have to travel together like last time, Lamont can do it. Otherwise, Godot can do it. If Godot and Karasz make up, then Godot no matter what.
