Wolvermean

Wolvermean is the leader of the Galactic Ninjas and self proclaimed "Thief of Memories" who appears in Power Rangers Super Ninja Steel. He is voiced by Jamie Lineham.

History
Wolvermean first appears in the Warrior Dome, where he introduces himself and his three ninja followers, Speedwing, Rygore, and Venoma. He also explains the Ninja Medallions, four powerful pendants that are the source of the Galactic Ninja's powers. He is the first of the ninjas to face the rangers.

In his first fight, he succeeds in stealing all but Calvin and Levi's memories before returning to the Warrior Dome. After their memories are retrieved, he fights them again but is defeated by the Lion Fire Red Ranger and the Yellow Ranger. He is gigantified, but is quickly defeated by the Ninja Ultrazord. Wolvermean survives, but loses his Ninja Medallion in the process, which unbeknownst to him is taken by Odius. He acknowledges the rangers' strength, but assures that he and his Galactic Ninjas will destroy them, and returns to the Warrior Dome.
