The Magical Phantom

Vlad realized what he had to do to get Danny. Kill his family. But his friends are caught in the crossfire & things go bad. Danny, left alone, goes to the GZ where Clockwork tells him of a place that could use another hero. So after changing Danny back to 11 but letting him retain his memories/powers Clockwork ships him to Hogwarts to learn magic & help in the war with Voldemort.
