I have no idea what an OOC is for but everyone else seems to be redeclaring interest so I shall as well! (also posted character sheet over in the character sheet area)[/quote]

An OOC is for out of character talk so players can discuss plans, relationships and plot ideas. As well as give general feedback and thoughts towards the RP in general. Ideally this is where you hash out what exactly you want to accomplish in the RP and how to do it.

Anyone have a suggestion for a different superhero name for Kara. Supergirl and Superwoman will not be considered.

Looked at the D.C. Wikia and only other names I saw were Matrix, Andromeda, and one from Krypton's fiction, same fiction that Nightwing came from.[/quote]

Valkyrie seems like a good fit. 

Knockout and Bombshell both come to mind, although they are used by other DC Characters, albeit minor ones. 

As suggested, a military rank could work if it aligns with her backstory. 

Galatea is also a good one for reason you're already aware of. Other names for Greek Mythology come to mind such as Antigone, and Nike.
