―ChangeMermaid's roll call[src]

Sayaka Nagisa (渚 さやか Nagisa Sayaka) is ChangeMermaid (チェンジマーメイド Chenji Mameido) of the Changemen.



Former Strategic Branch officer with the Earth Defense Force. A genius with the "brain of a computer," Sayaka is also an inventor. A stickler for manners and etiquette, her "Miss Perfection" attitude frequently clashes with Mai's rough and tomboyish nature. A loving and caring person in a motherly way, Sayaka, like Hiryuu, often becomes more emotionally attached to cases than she should, which is why the two most likely share a good rapport. She also loves animals. Frequently comes up with the plans to be rid of or discover the Gozma's attacks, she always gladly works with Hiryuu. Hiryuu always shows constant faith in her, as shown when her invention of the Anti-Grav Belt to combat a flying Space Beast Warrior initially failed, injuring and angering the others on the team, while Hiryuu remained with her to continue its testing.Tvicon.png TV STORY-Ep. 19: Bet on Sayaka! Due to moments like this, the team wonders if Hiryuu and Sayaka are an item, and have tormented them about it.

As ChangeMermaid, she is armed with the Change Sword and Mermaid Zooka, which becomes the scope for the Power Bazooka. Due to its size, the power of the Mermaid Zooka itself is weaker than the rest. Her unique combat attribute is the grace of her movements, while anticipating her opponents next move with her intelligence, often being able to discover her opponent's weak points.

Ranger Key

The ChangeMermaid Ranger Key.

The ChangeMermaid Ranger Key (チェンジマーメイドレンジャーキー Chenji Māmeido Renjā Kī) is Sayaka's personal Ranger Key and what became of her powers after she along with the rest of the 34 Super Sentai sacrificed their powers to end the Great Legend War.

This key along with the majority of the Ranger Keys were collected by the Red Pirates and later used by the Gokaigers. The ChangeMermaid Ranger Key was mainly used by Luka Millfy (Gokai Yellow), who used it to fight as ChangeMermaid.

The Changeman keys, along with all the Ranger Keys of the first 33 Super Sentai, were briefly taken by the Black Cross King and turned into Ranger puppets that were fought by the Gokaigers and the Goseigers. The puppet Changemen fired their Power Bazooka alongside the Flashmen, Maskmen, Livemen, and Turborangers, only to be swiftly defeated by the individual finisher attacks of the Gokaigers and Goseigers as they emerged from the resulting fireball.

After Zangyack were finally defeated, the Gokaigers gave the Ranger Keys back to their rightful owners. Sayaka received her key and became ChangeMermaid once more. Tvicon.png TV STORY-Final Ep.: Farewell Space Pirates
