How Kristen joined the Tourney
Kristen, leader of the Alliance of the Dark Scorpion, hears of the Crimson Lightning who defeated her old friend, Mokujin. Kristen decides to form the Alliance of the Dark Scorpion. In the meantime, she encounters Maleficent, the nemesis of Aurora. Kristen and Maleficent soon joined forces. Afterwards, Kristen encounters Feng Wei. They have a brief conversation, then she, Maleficent and Feng join forces. After this, Kristen returned to the school and used the Treehouse Telephone to call Black Shadow, Jafar, Ursula, Black Adam, Night Terror, Dr. Neo Cortex, Lu Bu, Nephrite, Vilgax, Ghirahim, Wolf O'Donnell, and Raoh to join forces with Kristen. All of them accepted her request, and they all decided to take part in the Smash Bros. Tourney.
