Hawkman #4

It's Hawkman vs. Hall in the brawl for all of Thanagar! Having just teleported across the galaxy, Earthman Carter Hall squares off against Thanagarian space cop Katar Hol in an all-Hawkman slugfest. Katar provides the next piece of the puzzle in Carter's quest to unlock the secrets of his own past-an alien artifact that immediately zooms him back to Earth. While puzzling out the space doohickey's purpose, Carter finds himself whisked away once again, only to come face to face with an old Justice League teammate.
