Magis

"Seaick Power of Life! Gosei Green!"

- Gosei Green's roll call

Magis (マジス), also known as Gosei Green (ゴセイグリーン), was a member of the Goseigers, specifically of the Seaick Tribe, being the former partner of Hyde (Gosei Blue), and the second Gosei Angel of the sea. Had he survived and officially joined the team, he would've made the team a six-man group of core Rangers.

Biography
Sometime prior to episode 1 (as seen in episode 10), it was revealed that Magis had saved Hyde's life by transforming into Gosei Green and fighting Kurasunigo of 5000°C; but although he saved Hyde's life, unfortunately he paid the price with his own life. In Episode 10, it was also revealed that Hyde leaves flowers at the place where Magis died in his arms.

Unlike other dead heroes who were replaced, Magis did not fight in the Great Legend War. In-universe, it is possible he did not fight because he did not really fight on Earth, and his true home world was the Gosei World.

Super Sentai Versus Series Theater
After seeing Sen'ichi Enari (DekaGreen) in the Dekaranger VS movies, Dekaranger vs. Abaranger and Magiranger vs. Dekaranger, Hyde is suspicious due to his similarity to Magis (both were played by actor Yousuke Itou).

Gosei Green
Magis presumably transformed into Gosei Green by putting a Gosei Green Change Card in his Tensouder. Gosei Green is a Seaick Tribe power wielder who fought with the power of a dolphin.

Mecha
Gosei Green's mecha is unknown, though he presumably had a Dophin-themed one. It is possible (though unconfirmed) it was Gosei Dolphin from Gosei Wonder, or a similar mecha.

Portrayal
Magis is portrayed by Yousuke Ito (伊藤 陽佑), who previously portrayed Sen'ichi "Sen-chan" Enari/DekaGreen in Tokusou Sentai Dekaranger. As Gosei Green, his suit actor was Yasuhiro Takeuchi (竹内 康博), who also served as suit actor for Gosei Red.
