Let me delve into a never ending dream.

She isn't evil she's just crashing out cuz mark destroyed her world, killed most of her friends and then paralyzed her so she just has to sit there and watch it happen everyday - which yeah made her a little unhinged but that's understandable

It broke her to the point that her mental blocks give out - letting her use her powers to the fullest extent, fighting mark and winning. She almost dies too but uses marks body to rebuild herself (she eats all his limbs😔)

Some sympathizing doctors hide her and Mark - cuz of course he can't just die and leave her alone - and the doctors couldn't kill him. But Eve, realizing she'll probably need help to stop Omniman wants to try to brainwash Mark the way she did in her backstory

Mark wakes up later, still fucked up completely, wanting to kill eve, but bro got no limbs so thats not going to work lol. She tries to erase his memories and put in mental blocks like she had so he can't kill (or disobey her). It doesn't work at first,

But cuz this mark is... Insanely obsessed with her he eventually gives in. So he gets put in a tube to regenerate. 

Eve stats a rebellion - probably with the help of dinosaurus - assembling all heroes who are still alive to kill nolan

It goes as well as you'd expect - nolan is almost impossible to kill, so they use the "the son you thought died because of your incompetence is actually alive and he's brainwashed to hate you :3" mental nuke to get him unstable enough and beaten down enough for eve to control him

So with both evil graysons now under control they start rebuilding. Alan shows up, Eve gets him to help her rebuild earth. They fight Thragg, find out mark is the fucking emperor (cuz OF COURSE he is), the viltrumites execute Thragg (eve isn't taking any chances)

I also think it would be an interesting position for eve to be in - even though SHE saved earth, SHE went up against the viltrume empire, SHE is the good guy Mark still gets to be the main character SOMEHOW. 

And that motherfucker is still weirdly obsessed with her😭😭😭

Also i think she'd get together with Rex - they lead the rebellion together (kind of. He was her emotional support) And Mark is very jealous. 

Maybe Eve could get an heir from Mark - a child she can raise to be the new emperor, and who will be a good one. Just to add to the drama

Mark also regains his memories at some point - he even changes for the better, but he's still a weird non-human freak with little empathy. He's also weaker cuz all his limbs are not fully viltrumite.

The robot parts are there to keep her body from shifting too much - since the mental blocks are gone. But she can basically shapeshift and heal immediately - as long as she's not worn out or insta-killed she's practically unstoppable.
