Witch

Witches are humans that possess supernatural and magical powers. In traditional folklore, witches are elderly hags, dressed in rages, that use dark magic to cause mischief and chaos.

In 1665 (before Dimmsdale was named), Timmy Turner, who had travelled back in time, discovered that Alden Bitterroot was a witch. Alden planned to trick the townspeople into naming the town after him. He passed himself off as a witch hunter, but all he really did was pass of animals and objects as witches.

Magical Powers
Alden Bitterroot was able to project his magical abilities through his hands. When using his magic, his hands and body would be covered in a greenish glow. His powers included the ability to levitate, project green energy bolts, block Cosmo and Wanda's magic and fly on his broom.
