TigerSharks Protectors of Water-O, the team members are: •
Mako (voiced by
Peter Newman) - A gifted
scuba diver, he is considered the field commander of the TigerSharks. He transforms into a human/
mako shark hybrid, which grants him incredible speed underwater. Mako also uses his forearm fins and head fin to slice through metal. •
Walro (voiced by
Earl Hammond) - The scientific and mechanical genius who created the Fish Tank. He acts as the advisor of the team and is very respected by his comrades. Walro turns into a human/
walrus hybrid. He wields a cane that has a wide variety of weapons. •
Rodolfo "Dolph" (voiced by
Larry Kenney) - Octavia's lieutenant aboard the SARK, he is also an natural scuba diver. Dolph loves a good joke, even on himself; yet he's all business when such is called for, and his work gets results that speak for themselves. Dolph turns into a human/
dolphin hybrid, which makes him very maneuverable underwater and can shoot a strong jet of water from his blowhole. Dolph is unable to breathe underwater in his aquatic form and must surface often to replenish his air supply. •
Octavia (voiced by
Camille Bonora) - Captain of the SARK, communications technician and main strategist. Octavia turns into a human/
octopus hybrid with tentacles in place of hair. •
Lorca - The team's mechanic and often helps Walro to repair or build new machines. He is also the team's strongest member. Lorca turns into a human/
orca hybrid. Like Dolph, he cannot breathe underwater in his aquatic form, and therefore must surface frequently for oxygen. He speaks with an Australian accent. •
Bronc - A teenager who, along with his sister Angel, works as an assistant aboard the SARK. Bronc is very adventurous and sometimes reckless. He turns into a human/
seahorse hybrid, hence his name, which is derived from "
Bronco". •
Angel - Another teenage member of the SARK's crew. Angel is more serious and responsible than her brother. She turns into a human/
angelfish hybrid. •
Gupp - The TigerSharks' pet
Cocker Spaniel. His features, including flipper-shaped legs and pin teeth, resemble a
pinniped. •
SARK A.I. - The
artificial intelligence of the SARK.
Villains The show featured two major antagonists, both with teams of followers. Both are in alliance to conquer Water-O and destroy the TigerSharks, but plan to betray each other once these goals are met. They are: •
The Mantannas - A race of alien sea creatures who arrived on Water-O after their home planet dried up. The Mantannas cannot breathe water and use a water-breathing apparatus to survive on land. •
T-Ray (voiced by
Larry Kenney) - T-Ray is a
manta ray hybrid-type creature and the leader of the Mantannas. He wields a whip. •
Wall-Eye (voiced by
Peter Newman) - A

aide-de-camp. He can hypnotize people by spinning his eyes. •

grouper hybrid. He wears a belt that can shoot electrical blasts. •
Dredge - An
eel-like mutant who carries a pet
electric eel on his back. •
Carper and
Weakfish - Two
mermen with frog-like faces. Identical twin brothers who (as befitting their names) whine and complain about everything. Carper has green skin while Weakfish has purple skin. They are also shown to have a fear of dogs as seen in the first episode when they are frightened away by Gupp. •
Captain Bizzarly (voiced by Earl Hammond) - The captain of a crew of
pirate with
aquaphobia who controlled all crime-related activities on the vast oceans of Water-O until the Waterians froze him and his crew in ice many years ago. T-Ray freed Bizzarly and his crew expecting them to join forces, though they secretly plan to betray the other once their goals are accomplished. •
