Long name I know, but what if the AU's had opposite personalities?

I'm going to do the star sanses and the bad sanses first, then maybe move on to some others

Nightmare:

New swapsona: Dispite his large and scary original appearance, he can be a big softie/baby sometimes when he's around someone he likes, If someone reminds him of his past he will cry but attempt to hide it, he can be serious in battle, But is actually and usually more afraid of the person he's fighting. He will quite literally beg for attention whenever he feels like it, and is very...Submissive, his weak points are his skull (specifically the top) and certain areas in his tentacles

Dream:

New swapsona: he still has his innocent yellow appearance, But can be manipulative and evil, He uses his positive emotion to manipulate people and then betrays them by leaving with no warning, Though is he truly likes/loves someone, he will show them his real self and tends to be very flirty, very hard to fluster though not impossible, His weak points are his neck, and his legs

Dust:

More like Killer, Dust is not calm anymore but he is chaotic as HELL and tends to get in a lot of trouble, he drags everyone in a dangerous spot and Killer has to drag him out of it

Killer:

More like dust, he is more mature now and calmer, always saving Dust

Horror:

He is a terrible cook, he is also more like blueberry, not as scary as he looks

Blue:

Instead of happy and energetic, hes very strict, like a military general

Ink:

He absolutely hates creative stuff, but he does it because it's his job, he also still has no emotion, and he isn't good at faking it without his vials, he can also remember things very well

Error:

Hates destroying, but does it bc it's his job, he likes to draw and he doesn't create dolls like original Error, Error absolutely HATES cute things and likes creepy sh*t, hes not that much of an a*shole

(Imma add more characters later, Still thinkin...)
