The Savage Hawkman, Volume 1: Darkness Rising

Archaeological linguist Carter Hall was done being Hawkman. Hawkman, however, was not done with Carter Hall. The mysterious Nth metal that powered Carter's armor fused itself to his body, unlocking powers he never knew he possessed. Far from leaving Hawkman behind, Carter Hall now carries Hawkman with him always and can call upon his powers at any time.
