A short time ago, I reviewed DC Universe Online Legends #9 noting that Supergirl was portrayed in her more classic Matrix style costume of red skirt and full blue shirt. Some folks including poster Azaketh clued me into the fact that that is not the costume that Supergirl wears in the game. Tracking alternate Supergirl costumes is something of a hobby.
Above is a picture of how Supergirl looks in the DCUO game, sporting the belly shirt as well as a red skirt. This is a combination that hasn't been used too much in the past.
If you look around the internet, you can see clips from the game. As described by Azaketh in their posts, Supergirl is something of a mini-boss in the game. You have to trick her to get close to either Kryptonite or a red sun cage to damage her. So ... yes ... you have to battle (rather than team up with) Supergirl when you play. Most of the clips are players trashing her since they want to show their skills.
I did like that Summer Glau provides her voice in the game, reprising the role from the Superman/Batman:Apocalypse movie.
But looking back at the costume design, here is the Supergirl DCUO production sheet. At least here, the costume is the same as in the comic. So I wonder where along the way the skirt changed colors.
I wonder if that change was known at the time the Terry Dodson Women of the DC Universe Supergirl bust was in production. This is the only other place I have seen the red skirt/belly shirt combination.
I also think it fascinating that DC is changing the costumes in the September relaunch so wildly. You would think they would want to streamline the look of their characters so people who play the game would know what to look for in the comic book store. Or maybe the comic readers would want to see the same costumes in the game. If DC wants to bring in new audiences, they should make it easy.
As always, I am not commenting on the portrayal of Supergirl in the game or book. Neither sounds particularly great.
