I don't know if you've asked about this before, but would you be able to use the Kimiyo Hoshi Doctor Light? As I believe she was in the league? Again apologies if this is something you've already discussed haha!

EDIT: In regards to my Sponsor/Sample Post, I never specified as to whether this was Barry or Wally! Should I make it Barry seeing as you're planning on a Kid Flash type villain in the future?
