HEY! It's Yoko, as she appears in DOUBLE K, the Gurren-Lagann buddy cop alternate universe thing I'm working on (as always, if you're confused, check here,here, and here for more info/art)
As per and 's brilliant suggestion, Yoko's a mysterious vigilante who periodically appears to help (and occasionally hinder) our intrepid buddy cop heroes, Kamina and Kittan. Who is she REALLY though?! You'll just have to wait to find out. (The answer is hilariously anti-climactic, though)
I'm not completely happy with her design just yet, so expect to see another iteration of her up soon - along with art of her SECRET IDENTITY!! Oooooo
I believe I need to check out your alternative universe for GL's characters. I know I like this new version of Yoko--the art is like an American comic, like DC Comics' Paul Dini took a shot at drawing her.
You're a really good artist!
Her name is Yoko Littner.
Anyway, you get three badass points.
