I love how Supergirl has the classic up, up, and away pose. Notice that the cake which Supergirl is standing on is bronze and covered in gears.
This Supergirl isn’t powered by a Yellow Sun. This Supergirl is rocket powered. The flames shooting out of the rocket pack are so cool. I love how the rocket pack is covered in gears.
I really like how Supergirl looks like a cross between the traditional Supergirl we all know and love and the Rocketeer.
I really how Supergirl has a steampunk chest plate that is hooked to the rocket pack.
Supergirl’s outfit is amazing. All of the outfit is colored black, white, and bronze. It is hard to tell from the angle, but she has bronze goggles on the top of her head. She has a black top with bronze frills. As I mentioned earlier, her corset / chest plate is bronze and has tube / wires running back to the rocket pack. She has a black skirt, white bloomers with bronze trim, and black garters. All these elements combined for an extremely cool steampunk costume.
