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.
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.
Later, after Speedwing and Rygore's deaths by the rangers, Wolvermean learns by Venoma that Odius uses theirs medallions to his Zord Foxatron and is furious. He wants to get back his medallion but Odius answers him that he will get back it if he succeeds to destroy the rangers or he will be destroy as well by Foxatron. Wolvermean fights the rangers with Venoma but is defeated. He is gigantified by Cosmo and fights the Ninja Blaze Megazord but is easily pushed. Just at the moment that he is about to fight the rangers again, Odius kills him as stabs him with Foxatron's sword for his failure. Shortly before his death, Wovermean curses Odius calling her treacherous wicked witch.
- His Sentai counterpart is based on a badger instead of a wolverine.
