Hmmmmmmm.
-Must request that Uncle Minami was initally funded by Cadmus Labs, but when his results weren't up to Supergirl-clone levels they cut off funding. Because if we ever pursue that, it can link back to fun characters like Amanda Waller and, well, Galatea. *has a half-done 'Tea app, wut* AND BESIDES, Cadmus is a great name! It is like Desmond. It is a lurking villain to be pulled out whenever we want. c:
-ORRRRRR, if you recall the JL episode Ultimatum? Maxwell Lord supervising the cloned knockoff superheroes, the Ultimen? What if your Gravity Kidz were the first round, unsuccessful in power levels but with the life-spans of ordinary humans? And he or somebody in there let them go rather than, er. Discarding. As was probably the Cadmus directive. This is a push away from your backstory so don't do it if it doesn't appeal to you, but Max Lord is a name that Booster and Ted have deep ties to in their 'verse. So that's another way to go.
-Her sisters threatened her, too? Or just Mr. Mysterious Leader.
-I note you picked Steel instead of Dakota. ;D Any background with the Titans East, altercations with, opinions thereof?
-I guess what this backstory is really conspicuously missing is a villain or two. There are these placeholders for villains that you look like you're being careful not to name. And my request is that you name them, anchor her in this 'verse with some character connections that maybe she doesn't know she has.
