Crisis on Infinite Earths #9 (Facsimile Edition George Perez Cover)
GUY GARDNER IN ACTION!
The brief pause after the climactic destruction of so many worlds is interrupted by a new threat: an assembled team of villains led by Lex Luthor and Brainiac coordinate plans to destroy the remaining Earths if their leaders don't capitulate. Meanwhile, on Oa, Guy Gardner accepts a ring of power and a new mission as the Guardians' agent of vengeance. A full facsimile reprint from the series that forever changed the DC Universe.
