This is teasing at the edge of my head, but after several minutes of futile search attempts, I'm posting this here. It's a fanfic based on wildbow's Worm universe. I read it somewhere in the last year or two, unfortunately among dozens that tend to meld together in my head. Taylor, the protagonist of the regular story, has a different set of powers (the details of which are, unfortunately, escaping me). For some reason, she wins up assigned to a B-Team of PRT capes, I think to allow her to build up experience while staying anonymous. I do remember that she wears armor almost constantly to protect her identity. The other things that pop into my head:
- Wherever it was had a lot of snow
- I don't think it was near a major city
- One of her new teammates is named something like The Gobbler
- Their costume is a large bird suit, probably in the shape of a turkey
- They gain various powers based on what they eat. I don't think they gain any sort of accelerated metabolism or ability to eat unusual things, so they have to bring food with them and exercise frequently to keep the weight off
- Since their group seldom actually has to fight, they primarily get called in to talk to schools about the importance of healthy eating
- It's later revealed, maybe in a vignette from their point of view, that they used to be a minor criminal until an ill-advised attempt to use energy drinks to escape the authorities led to them sugar-crashing and getting captured
- Despite that criminal origin, I remember them being fairly cheerful about being a hero, even if they're one that most people don't take seriously
Unfortunately, my searches for "gobbler" with keywords associated with Worm fanfic don't tend to fare very well because one of the prominent villains, Skidmark, has a tendency (at least in fanfic) to use "gobbler" with various bits of anatomy or scatological substances.
