Who uses black magic in the tempest?

In Shakespeare's "The Tempest," the character who uses black magic is Prospero. He is a former Duke of Milan who has been exiled to a remote island, where he gains control over supernatural forces through his knowledge of magic, which some may perceive as dark or manipulative. Prospero uses his magical abilities to orchestrate events that lead to his eventual reconciliation and restoration to power. His magic serves both as a tool for revenge and a means to achieve justice.
