During construction work on the Volpehart building one day seemingly at random Ryan found a piece of gold, and in the hope of finding more of it, he went back into the building. Angel had an uneasy premonition on the matter, but Ryan did not want to listen to her and promptly fell victim to an unearthly monster who was constantly looking for new victims, whose spiritual essence it could fed on.
Since after three days the police did not want to look for her brother, the desperate Angel turned to her special friends, the Turtles, and together they set out for the Volpehart Building. The Turtles succeeded after some effort, in finding Ryan alive in the camp of the monster and then brought him back to the surface and to his waiting sister.
Ryan's current status and his current relationship with his unusual rescuers remains unknown.
