To become a slime girl. I really want to be that. Like you don't even know
Some of the fantasies and dreams I have.
Anyway, Powers.
Regeneration from separated body parts. I just reabsorb my lost arm and I can regrow it.
Basic shape shifting and such.
Using slime to ensnare or entangle opponents.
Changing just how solid or liquidy I am
I am free lubricant.
And now Weakness
Regenerating my body takes a long time, and if I cannot reach the lost bits of my body, then I will need to absorb things and convert them into biomass, which also takes a while.
I'm still made of slime, and I can't exactly make myself opaque, so disguises are out of the question. Still I could change how I look and stuff, so it's more cosmetic for me more than anything.
My slimy tentacles are still made of slime. A strong enough person could rip right through them. They'd also have a weakness to blades.
I can't become fully solid like a brick wall. My maximum consistency would be that of ballistic gel. And though I may turn my body to liquid, my core would likely not be able to fit down whatever drain I hill go down.
No downsides here other than people could slip if they walk over me.
And finally I have a core that acts as my brain. That is my weak point. If that dies, then I am dead.
