C.F. Volpehart

C.F. Volpehart was a European explorer 1000 years ago. He was summoned to the "New World" by the Necro Monster, appealing to the greed of the Europeans. Volpehart killed a native who had fashioned a spear made from the meteor that accompanied the Necro Monster's descent to earth and took it. With the monster's influence, Volpehart grew immensely rich.

In the early 2000s, a young man named stumbled upon a golden coin with Volpehart's name on it whilst working a construction job. Ryan traced the coin to the Volpehart Building and went through a golden door, disappearing. Ryan's sister, worried about her brother, went to her friends the for help.

When Angel and the Turtles arrived at the Volpehart Building, they met an old man who claimed to be Volpehart's heir and told them the story of Volpehart.

The Turtles went in through the golden door and tangled with the Necro Monster, rescuing Ryan and finding the Meteor spear and seemingly slaying the beast with it. Upon its defeat, the old man tells Angel he's finally free, clarifying that he himself is C.F. Volpehart moments before crumbling to dust.
