Why hello! Beth again. I thought I'd already done this, but oops, I hadn't.
This is Dick Grayson, who is a sort of 'Nolanverse what-if.' He comes from a storyline set between Batman Begins and The Dark Knight. Basically, he's comics canon until his parents' deaths, when he was shuffled off into the Gotham City foster care system. He took up vigilante activity independently after Batman sightings hit the papers, but without equipment or a billionaire's support, he was basically an exceptionally acrobatic, parkour-loving kid in a ski mask.
Eventually, of course, he ran into Batman and after a bunch of go homes he eventually did something tremendously right and earned some respect. He skipped Robin entirely and entered the fray as Nightwing, and while he trained under and took orders from the Bat, he also had his own crimefighting going on as a side-gig.
Anyway! That's it here. I plan to get him active soon, so if anyone wants plot, just let me know!
