Assist Trophy

Overview
''This strange capsule contains a guest character who will aid you in your battle. Who will emerge? Grab it to find out! Maybe it'll be a famous character from a popular game, or perhaps a goofy sidekick here to prove his or her worth. Too bad you can't choose who shows up or control them...''
