Predator Hawk was a former soldier of the Battle Bird Armada until he was put to jail for insubordination.  He was freed by the Babylon Rouges, but eventually left them to work for Mammoth Mogul as one of the Fearsome Four and then a member of the Destructix.  However, since Lightning Lynx's absence, he and the other two remaining members haven't been the same.  Under Fiona's leadership, he and the others team up with Sonic and the Freedom Fighters to bring Lightning back from the Raiju Clan.

Being that Predator Hawk's a bird, you would think that his voice should sound like a parrot.  However, I think it's safe to say that I want just the typical voice of a high school or college athlete.  Nothing too special.  Just be sure to give him some attitude.
