Norvirus Turbo

Norvirus Turbo (also known as Turbo the Shark) is the main antagonist of the 1999 animated film, Fishing Season.

He was voiced by Gilbert Gottfried, who also played Iago in Aladdin.

Beginnings
He is a tiger shark, who revealing his evil persona. Turbo is first seen, ran against Mayor Cobrafish for mayor of the Reef. Derek and his partner Little Alan ran for Cobrafish, but despite that, Turbo rigged the election against Mayor Cobrafish by putting in dead people and pets as people who voted for him and won the election. Despite that, Turbo turned bitter and evil, and won the “Shark of the Year” award and take over the Reef for himself.

Fishing Season
After years of return, Turbo frames Mayor Cobrafish for poisoning sharks with night howler serum, just so his cure won't work. He then terrorized the Reef, leaving it's people with no homes and also kidnaps Nellie.

After Derek is separated from his friends, Tom and his ex-sidekick Dexter the Chum ambushes him and reveals that Tom and other sharks actually need to create the animal cruelty program by eating fish.

Later, Derek and Little Alan followed him to Cliffside Asylum, and found him terrorizing Dexter. However, he noticed Derek and confessed his plot to him, stating that he has only framed (and later planned to betray) Cobrafish so he can silence all those fish who vote against him. He locked Derek and Little Alan inside the crate, planning to kill them as food.

However, after Derek, Little Alan and Nellie escaped through the abandoned ship, Derek told Bob and Sir Crab (the two dim-witted crabs) about Tom's plans, and then, after the fight, he defeats Tom by kicking him by the fin and sending him into the crate, trapping him.

Personality
Turbo is vicious, arrogant, power-hungry, temperamental, antagonistic, evil-minded, greedy, cruel, malicious and sadistic. He cares about nothing but himself, and he would terrorize the entire reef just for power, control and money. He seems to love killing fishes, after showing his past victims.
