Bruce is first seen in the film when Marlin accidentally comes face-to-face with him when the clownfish began to swim off to go find his son Nemo. Even after Bruce politely introduced himself with a huge grin, Marlin and Dory seemed uneasy.
Seeing this, Bruce said that he understood, saying, “Why trust a shark, right?” He then turns to leave, only for the shark to turn quickly and snap his teeth at them, just barely missing their mark. Even though it scares Marlin (who hides behind Dory) and Dory, Bruce gets a good laugh out of it. Nemo is a very energetic young clownfish. He is very eager to go to school at the beginning of the movie, but lazy at the end. He is also quite friendly with anyone he meets. Dory is a very optimistic and kind, but ditzy and forgetful fish. This is because she suffers from short term memory loss.
