Rough idea of my Janus? You could say I have something like that, yeah.

Her motivation for becoming a hero would be getting to feel like she has personal agency for once, in an environment with minimal perceived repercussions and more chances to make a difference. There were a few other reasons she keeps a secret identity that I thought of and can't quite remember, but I think one of them was related to a supervillain.

The three obligations I had in mind were Job - Intern, School - Photography Club, and some kind of home obligation I haven't quite sorted out. The first two were chosen because it might be easier to make potential plot developments with them. Her Mask would be Freak-type because yeah.

For power I was thinking Insect/Rodent Control + Senses or Impossible Mobility + Senses for "like a C-list supervillain" and "generic all-rounder", respectively. Which was supposed to be tied to the idea of being-a-hero-but-not-quite-a-100%-hero that fits well with the Janus theme. Plus the other three powers didn't really resonate with me as much; although I was briefly entertaining Substance Mimicry + Insect/Rodent Control and themeing it with a weird metaphor of "becoming the city and controlling its inhabitants" or something like that. 

No cape name in mind, but her real name is going to be Hana. I had it in my head that her personality would seem neatly compartmentalized, except it turns out all the compartments are on fire. 

EDIT: also I had a strange idea where Social - Best Friend was one of the obligations but that person was another PC for maximum hilarity/drama
