Doctor Ulshade

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

Doctor Ulshade (ドクター・ウルシェード) was 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 reawoken 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 occurance), never mind his old age.
