@M was a Super Smash Bros. Melee tournament held in Melbourne, Australia, on February 14, 2005. It was the second National Australian tournament featuring players from Japan, Victoria, Western Australia, Queensland and South Australia. Captain Jack was a special guest and placed first, while Kupo placed second, defeating long time Australian rival Quetzalcoatl and cementing her place as Australia's best for well over a year after the tournament.
@M featured two main Smash tournaments which focused on singles and doubles. However, the results for the doubles event have been lost to history.
