The roster for "Injustice: Gods Among Us" continues to grow well beyond expectations with WB Games and NetherRealm Studios revealing the two newest character to join the fighter's roster. In the newest installment of its Injustice Battle Arena Weekly Match-Up videos, the studio unveiled new footage of Sinestro and Hawkgirl bringing their expertise to the battlefield.

While the new footage was sparse, Sinestro fights in all his Sinestro Corps glory, donning a yellow ring and using deadly constructs to batter his opponents, including deadly insect pincers and a giant yellow fist. The footage also teased a finishing move where Sinestro crushes his opponent between two meteors. Hawkgirl comes equipped with her Nth Metal mace and uses her flight to get a leg-up on her opponent.
