Night Terror

How Night Terror joined the Tourney
Before the events of Super Smash Bros. Tourney, Nightmare met with Raphael Sorel in the Ostrheinsburg Chapel and defeated him. As he stepped forward to kill the man and harvest his soul, Siegfried's mind started to struggle with SoulEdge for freedom. Raphael, watching as Nightmare stood motionless as a result of the mind struggle, released an attack and pierced SoulEdge's eye. This allowed Siegfried to reclaim his body and also released the holy blade SoulCalibur from within SoulEdge. In a state of temporary sanity, Siegfried then drove the holy sword into the cursed Soul Edge and sealed both together, nullifying both powers. However, the will of Soul Edge escaped the sword and entered the dark blue armour that Siegfried quickly discarded after reclaiming his body. Eventually, the mysterious immortal Zasalamel found the armor and created a new body for the immobile Soul Edge out of the countless evil souls haunting Ostrheinsburg. This new Nightmare restarted his reign of terror in search of Siegfried and the rest of Soul Edge, as well as a new host to escape into, as the new body was heavily unstable. Just then, Nightmare encountered Oni Akuma and he entered the Smash Bros. Tourney to stop him by transforming into Night Terror.
