|~ Gill explaining his plan to help Nemo escape the tank.|
Gill is the tetartagonist of Finding Nemo, and makes a minor return in the sequel, Finding Dory. He is the leader of the Tank Gang and a close friend with Nemo whom he met at the dentist's fishtank in Sydney, Australia. He is the genius behind the idea of getting Nemo and the others in the tank to escape by stopping the rotating machine with a pebble. When the plan unfortunately failed almost resulting in Nemo's life, they thought of a better one the next day when there was a special fish tank system put in place. Nemo faked dying and after a matter of crazy things happening he went down a drain and was never seen by Darla again. A few days after Nemo is finally reunited with his father, Gill and the others from the tank are shown to have escaped and are swimming happily in the ocean.
He was voiced by Willem Dafoe.
Gill's only dream is to escape from the tank. He had made several escape attempts, but the first time, he landed on dental tools, giving him severe scars on his right side, and destroying his right fin. His appearance is modeled after the voice actor who does his voice, especially the coloring around his mouth to show the deep wrinkles that Dafoe has on his face.
He is the leader of the fish living inside the dentist's office fish tank called the Tank Gang.
Unlike the other Tank Gang members, Gill had a neutral reaction to Nemo's entrance. He also told Nemo to swim out of the tube he was stuck in without anyone's help. Learning that because Nemo is a young boy who can fit through small tubes, Gill immediately ordered him to use a pebble to stop the aquarium filter. With the filter sabotaged, he knew the dentist will put the fish in bags and they will have the opportunity to return to the ocean.
Eventually, Gill helps Nemo escape the office by jumping onto the dentist's mirror to catapult the clownfish into the air so that he lands into a sink leading to a drain, which leads to the ocean. After Dr. Sherman puts Gill back into the tank, the Tank Gang congratulates him on finally succeeding in helping Nemo return to the ocean.
At the end of the film, Gill and the other Tank Gang members manage to escape from Dr. Sherman's office. Since Dr. Sherman's new AquaScum 2003 has broken down, he has to take his fish out, put them in bags, and clean the tank himself, and while he complains to Barbara about the device breaking when it has a lifetime guarantee and is maintenance free, Gill and the others make their way out of the office. They are seen having crossed the street and jumped into the ocean to their freedom, although still trapped in the plastic bags (they presumably managed to get out by the ending credits).
In Finding Dory, Gill, along with the rest of the Tank Gang, appears in the post-credits scene. They are still trapped in their respective bags, now covered with algae, and then captured by the Marine Life Institute volunteers.
- Gill's species, Moorish Idols, are notoriously difficult to keep in captivity due to their diet and mannerisms. This may be an interesting way to show Gill's deep desire for escape from the aquarium and into the ocean. In addition, Gill was pressuring Nemo to follow his challenging orders on his escape plan.
- Gill's voice, as Dafoe said, is based on the character Earl Copen, whom he plays in the movie Animal Factory.
