While Hawkeye is traditionally just a normal human trained to a high level of skill, Ultimate Hawkeye was altered via some type of experimental optical surgery. His superhuman accuracy also extends beyond archery, to anything he can throw like 616 Bullseye, to the extent that he once escapes captivity by pulling out his own fingernails to use as weapons. Whether or not his teammates know of his augmentations is unknown, with the exception of Nick Fury, who has confirmed his knowledge, but it would appear that, in Hawkeye's favor, they remain unaware of his full abilities. It has also been remarked that before the "Ultimate Hawkeye" miniseries, he claimed to need to wear corrective goggles to see properly, but it appears that that too may have been a ruse.
