In the Finding Dory animation, almost all of the characters have a psychological problem or disability. For example, one of Nemo's fin is much smaller than the other. Bailey is a whale struggling with lack of confidence. Hank the octopus is missing one of his tentacles and is very afraid of the open ocean. Becky is mentally unstable and very unstable. Destiny has difficulty seeing far away, meaning she is nearsighted. Nemo's father, Marlin, has anxiety due to trauma from his family. And the hero of the story, Dory, is a fish that loses its memory every 10 seconds. In other words, despite all their disabilities, they can become a whole by helping each other.
