Bob Reynolds

He has a complex personality, divided between an idealistic hero and a being corrupted by his unstable psyche. He is kind and driven to protect others, but suffers from extreme mental instability, which includes mood swings, delusions of grandeur, and a profound agoraphobia (fear of open spaces), which leads him to avoid unleashing his full power. His personality is divided between that of the hero Sentry and that of his dark alter ego, the Void, who is cold and destructive.
