It was the fifth annual event in the Final Battle chronology, with the first in 2002.
Background
Final Battle featured nine professional wrestling matches involving wrestlers from pre-existing scripted feuds and storylines. Wrestlers were portrayed as either villains or heroes in the scripted events that built tension and culminated in a wrestling match.
One of the show's two main events featured Nigel McGuinness defending the ROH World Championship in a Four Way Fray against Bryan Danielson, Chris Hero and Takeshi Morishima. However, the night before, McGuinness was severely injured in his defense against Austin Aries. During the match, Aries dove from the ring, smashing Nigel's face on the edge of the guard rail, resulting in a concussion, a broken nose and a gash about his eye that needed 15 stitches. As a result, Aries was added to the Four Way Fray, with the winner getting a shot at the ROH World Championship at the Sixth Anniversary Show.
