Kirby

Kirby was a small, pink creature who emerged from SM Atlantis in the Battle of the Halves/Alternates.

History
In the Battle of the Halves/Alternates, Blackout and Ynot were sucked into a crack in time that led to ancient Japan. SM Atlantis then crashed into the sea next to them and Kirby, Mario, Luigi, Samus Aran, Link, and Fox McCloud emerged from the damaged city-ship. Ynot noticed Kirby and his allies and exclaimed "You have got to be joking me", but both he and Blackout were sucked into another crack in time before any interaction could be made.

Trivia
