Carter Hall was a priest in a past life, and still possesses the ability to bless mundane objects. For example, by muttering a prayer in front of a building's sprinkler system, he was once able to convert the water into Holy Water in order to destroy a vampire.
Hawkman was granted the ability to breathe underwater, by the god Poseidon.
The Nth metal knife which murdered Hawkman in his original incarnation as Khufu had an unusual effect upon his soul and that of his lover Chay-Ara (Hawkgirl). The pair are locked in a seemingly endless cycle of death and rebirth throughout the centuries. While not a superhuman power per se, this propensity for reincarnation has allowed Hawkman to cheat death and return to active duty in his current incarnation.
Due to his multiple incarnations and having memories of all of his past lives, Khufu/Hall has become proficient in many types of weaponry. As a result, he is an expert with a wide array of archaic weapons from his past lives, including battle axes, maces, swords, spears and shields. As Nighthawk, he was a marksman with a pistol. In addition, Carter Hall is sometimes depicted handling futuristic technology. He has used a Thanagarian ship called "The Brontadon", and during the Rann-Thanagar War used Rannian hard-light armor. Hawkman is even depicted using technologically advanced laser weaponry in a possible future.
Due to his many lives and vast amount of experience, Hall is a brilliant tactician, fierce warrior, and strong leader. At the same time, however, he is extremely intelligent (considered a leader in his field of history and archaeology) and expresses a deeply romantic side in relation to his beloved soul-mate. Often, Carter finds it difficult to balance between the "barbarian" of his past lives and the "gentleman" of his current incarnation. He also has an extremely innovative approach to science and technology.
