Magis

Magis (マジス), also known as Gosei Green (ゴセイグリーン), was a member of the Seaick Tribe, the former partner of Hyde (Gosei Blue), and the second Gosei Angel of the sea.

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 will leave 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 with the motif of an unidentified (presumably aquatic) creature. It is assumed he had a crab motif due to his partner sensing Magis's aura in a crab in Epic Zero. But, when looked closer, it is shown that Magis' suit is a repaint of Gosei Blue's suit.

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.
