Succubii have the flight, the innate understanding of social relationships, ability to read them, enhanced ability to charm, both through psychological reading and through literal seductive power (not used), dream viewing, dream manipulation, limited memory rewriting (requires them to be sleeping, is short-term only, and prone to failure; also not used), and probably more that I, again...forgot.
I'll see about looking up Succubus powers in various settings, and see what I want. I want most, but not all, of the powers. For instance, mind-reading I want a form of, but not as strong as in DMFA Cubi mindreading for instance. (And in this case, from the Slime half not Succubus half.)
I did however come up with the protagonist's superhero name. It's something that she very very very deliberately selected:
Wetgirl.
It seems like a lame name, and a name easy to make fun of, due to the nature of the innuendo of a name--but that's actually the point, that's actually precisely the reason she chose it as her superhero name. She doesn't want to be just a slime girl, she's a succubus and a slime girl, so she chose an alias that would pay homage to both halves of her, rather than just one.
And did so while remaining mostly family-friendly. Something that parents can't truly object to naming-wise, but which conveys the succubii heritage while also conveying her main power source, that being, her water affinity (since Slimes are more water than anything else).
Anyway, while I could have more to say, tonight? Tonight I need to listen to my body's urgings of sleep, so I'll be going to bed to hopefully beat covid as soon as possible.
