Master Chief

How Master Chief joined the Tourney
Master Chief continues his research on the Civil War. Disappointed that he was unable to recover the Civil War data during the King Of Iron Fist Tournament 4, Master Chief returns home and resumes his research. Each time his work hits a dead end, he is reminded of the data that he was unable to retrieve. At that point he received a letter addressed to her in a foreign language. Attached is an announcement of the Smash Bros. Tourney. In order to fulfill his hopes for forest rejuvenation, Master Chief decides to enter the tournament.
