Doctor Ulshade

"The seas of the Earth belong to me, and the cosmic sea belongs to me! Marine Brave, KYOOOOOOORYUUUUUUUU VIIIIIOLEEEEET!"

Doctor Ulshade (ドクター・ウルシェード) was the original Marine Hero (海の勇者), Kyoryu Violet (キョウリュウバイオレット) and the former partner of Zyudenryu Plezuon.

History
Ulshade is a genius scientist that created the Gaburivolver and the Zyuden Arms with the help from his granddaughter, Yayoi. He is also the first Kyoryuger to be active in modern times. This guy is not just brains, he’s also an expert on using the tools he has created. Ulshade had left the planet when the Deboss Army reawakened with his Zyudenryu partner to research the asteroids Deboss had arrived with, confident in the newest Kyoryugers to beat back the Deboss Army's advances. He’s returned to the rough welcome of the Deboss Army, and plans on retiring as a Kyoryuger, thanks to the fact that he tends to pop something out of place when overexcited (which is a common occurrence), never mind his old age. He indeed retired after returning to Earth and passed on the mantle of Kyoryu Violet to Yayoi.

Ranger Key
Kyoryu Violet I Key (初代キョウリュウバイオレットキー) is a Kyoryuger Ranger Key released as part of a set of thirteen Kyoryuger Ranger Keys in Bandai Premium. It is unknown if it will appear in a future crossover. Of course as with all Ranger Keys, should it exist, it would be able to transform one, i.e. one of the male Gokaigers, into Kyoryu Violet.

Portrayal
Doctor Ulshade is portrayed by Shigeru Chiba (千葉 繁), who is also the series' narrator and voice of the Kyoryugers' weapons. As Kyoryu Violet, his suit actor is Riichi Seike (清家 利一), who is also the suit actor for Dogold.
