Dr. Yamazake was the supervillain known as Dr. Polaris. Obsessed with building a transporter, Yamazake's continual disappointment with the superhero populace was what led him to tyranny. His belief that he could achieve teleportation through polarization was what hed to him becoming the villain he did become.
The magnetic field of his teleporter caused the surging energy to activate Yamazake's metagene, denying him physical form but granting him power over magentism. Bonded with the magnetic field, Yamazake was able to control metals beyond limit.
