Dolphin Evo

The Dolphin Evo appeared in 1983 TV series called Kagaku Sentai Dynaman. Dolphin Evo (イルカシンカ Irukashinka, 11) is the dolphin-theme Evolution Beast of the Tailed-People Clan Jashinka Empire. Dolphin Evo was created for a scheme to communicate with sea life to turn them against humans, thus allowing them to attack and sink ships at sea. The Evolution Beast initially attacks Marine Land to capture a marine life expert to help with the plan, confronting initially Shima and Rei before it escapes from the other Dynaman. During a battle with Shima, it knocks him deep into the ocean where he appears to drown until he is saved by a mermaid, who gives him the inspiration to go forth and defeat it to protect all marine creatures from its influence. During a final showdown, DynaBlue fights and defeats Dolphin Evo both on land and water before the team finishes it off, first with Super Dynamite, then with DynaRobo.
