Her first name needs to be spelled, "Shiera Hall." Source: https://injustice.dccomics.com/#tournaments/superfight4/2
its shayera hol thats that whos in the game
Oh yes, Hawkgirl's name has been an ongoing debate ever since her inception to this wiki. Let me take the time to clear it up. Who is it? Shiera Hall or Shayera Hall? Answer? Both are correct. Shiera and Shayera are virtually the same character, however, there are just a couple of critical differences. Shiera Hall is the Golden Age incarnation of Hawkgirl. Shayera Hol is the Silver Age incarnation of Hawkgirl, but she went under the codename of "Hawkwoman" and is actually from the planet Thanagar. Shiera Hall was born on Earth. Most of us are familiar with the Silver Age Hawkwoman (Shayera Hol) because of the TV shows Justice League and Justice League: Unlimited. :-) Again, they are pretty much the same character and it gets VERY confusing to differenciate the two because Hawkman's comic series kept getting rewritten or changed because DC Comics constantly changes its story continuity. I just visited Wikipedia for this information. :-)
However, in terms of Injustice: Gods Among Us, I am absolutely sure they are using the Shiera Hall version of Hawkgirl as confirmed by her in-game bio. In terms of this wiki, I believe the administrators are using the in-game bios and/or content as a basis for creating ALL the profiles, backgrounds, movesets, quotes and etc. for all on-disk characters on the playable roster. While the game does make strong, explicit references to Shayera Hol (i.e. her movesets are named after Thanagar, her clash and battle dialogue with Solomon Grundy and also Hawkgirl's S.T.A.R. Labs missions openly refer to her by that name), in terms of the info boxes and backgrounds for Hawkgirl's profile on this wiki, it should just be Shiera Hall because her in-game bio dictates that information. Here is some photographic evidence provided below.
