I've always been a fan of Yvonne Craig's version of Batgirl from the 1966 Batman TV series. She was just so damn adorable with the purple glittery suit she wore while protecting the streets of Gotham. This toy from Mattel pays tribute to that and was included in an extensive reveal of Comic-Con 2015 exclusives from Toys R Us.
Brave and beautiful in 6-inch scale, and rendered in actress Yvonne Craig’s likeness, this classic TV series Batgirl features dynamic, iconic colors, a two-sided soft goods cape and 16 points of articulation for ultimate playtime action and posing. Collectors can display her on the included base and choose between one of two retro cityscape backdrops.
Batgirl will be available next month at SDCC, but there's no information on how much it will cost. There's also no information on if it will be available to buy some time after the convention. So as of right now your best chance of getting one is at the con.
