Adolpho

Adolpho is a mutated dolphin who plans revenge on the world for polluting the ocean and putting dolphins in aquarium theme parks.

History
The pollution mutated the dolphins with the abilities to change into dolphin monsters with armored backs. He and his dolphins can manipulate the wild dolphins and whales to create whirlpools to sink ships, oil rigs, oceanography Stations, light houses and small islands, and other things at sea. His henchmen captured Ace during the Loonatics' aquatic recon and trapped Ace in the tentacles of a giant jellyfish.

While Lexi and Duck are rescuing Ace: Tech, Slam, and Rev see a whirlpool sinking Acmetropolis. Tech and Rev figure out what needs to be done. It took Lexi and Duck to rescue Ace, break the mind control on the whales and dolphins, and defeat Adolpho, putting him in an aquarium in Acmetropolis Prison, along with the other villains.
