Nintendo-All Stars occasionally has promotions, or campaigns, available for players to partake in. Somewhat similar to event Pokémon on the Pokémon series of games, promotions allow players to obtain various things over a certain period of time. Promotions are usually done in collaboration with other parts of the Nintendo franchise, such as merchandise like books, toys, the TCG, and the anime.

The password for this promotion came with specially marked copies of Nintendo All-Stars: Super Star Saga available in participating American Walmart stores starting April 27. Copies with the password were limited.
The character was eventually released in EUROGAMER throughout Europe, Australia and New Zealand, instead using a single password.

To celebrate Meta Knight Day, the password for unlocking Meta Knight as a playable character was made available within the October 2012 issue of the Nintendo Power magazine. Meta Knight was later made available in European regions with a shorter period of availability.
Due to the failure of the German Yahoo website to report the password, the promotion was cancelled and rescheduled.
