Marvel's Avengers: Hawkeye - Future Imperfect

After the A-Day disaster, Clint Barton and his mentee, Kate Bishop, were left on their own, deciding to search for the missing Nick Fury, and, in doing so, stumbled upon AIM's secret Tachyon Project, resulting in Clint's capture. Though Kate brought him back to the Avengers, peril doesn't leave him; he falls into a coma, witnessing a future vision that leaves him confused and defeated when he finally wakes. Armed with his bow, sword, and knowledge of the grim events to come, it's up to Hawkeye to stop the end of the world.
