Event 10: All-Star Battle Regulars
From SmashWiki, the Super Smash Bros. wiki
All-Star Battle Regulars (オールスター戦レギュラー, All-Star Battle Regular) is the 10th solo event match out of a total of 41 in Super Smash Bros. Brawl. This event match puts the player against the eight original starter characters from Super Smash Bros., two at a time. These opponents are, in order, Mario, Donkey Kong, Link, Samus, Yoshi, Kirby, Fox, and Pikachu. Note that this is the same order they appeared in on the original Super Smash Bros. opening movie and character selection screen. This is also in the order from the first characters chronologically by first appearance in a video game, which are Mario and Donkey Kong, to the last chronologically appearing of the eight, which is Pikachu.
