Johnny Cage looks over his Sunglasses and smirks. "This shouldn't take long."

Shinok slowly rises out of the ground and says "Bow to me."

Sareena is kneeling facing away from her opponent. "You should leave." Then she rises up and faces her opponent. "I don't know how long I can control it." As her eyes start to glow red.

Rain, as in water, falls from the sky and Rain, the character, materializes from it. "You are no match for the Prince of Edenia."

Ashrah does some fancy sword twirls. "I have come to slay you."

Jarek falls from the sky and lands face first on the ground. Then he gets up and says. "The Black Dragon live on!"

Ok that last one is a joke.
