While not the most intelligent Harpia to fly the skies, Ison is proud none the less, particularly of his plumage and of his hunting abilities. He can be a bit obnoxious, as he is prone to bragging and talking himself up, particularly if someone else is being discussed, always desiring the be the center of attention. He is also very noisy, and is seemingly incapable of doing anything quietly, other than when he is sneaking up on prey.
