Dory (Finding Nemo)

Dory is the deuteragonist of the 2003 Disney/Pixar film Finding Nemo and the titular protagonist of Finding Dory.

Why She Keeps Swimming

 * 1) She plays a large role in Marlin's journey to find Nemo. Some examples include:
 * 2) * Dory is able to read English. She successfully read the mask when Marlin was distracting the anglerfish.
 * 3) *When Dory spoke whale, the whale swallowed her and Marlin and brought them to Sydney.
 * 4) Ellen DeGeneres does a spectacular job voicing her.
 * 5) It is funny when Dory forgets something.
 * 6) Her memorable song, "Just keep swimming."
 * 7) She even had her own adventure in Finding Dory, where she went to find her parents, while accompanied by Nemo and Marlin until she was taken into the Marine Life Institute.
 * 8) *Unlike Mater in Cars 2, she is a strong main protagonist in Finding Dory, greatly evolving from comic relief and Marlin's sidekick in Finding Nemo to a fully developed and rather complex character in the sequel, and she still retains her funny moments here and there too without being annoying.
 * 9) Speaking of Finding Dory, her memory seems to have improved, as she addresses Marlin by his name for the first time and never gets Nemo's name wrong this time around.
 * 10) She is friendly and kind-hearted.
 * 11) She can quickly think her way out of difficult situations, despite having short-term memory loss, like using a baby carriage so she and Hank could get to the Open Ocean exhibit unspotted by humans, speaking whale to communicate with Destiny to help her swim through the pipes and tracking down the truck containing Marlin and Nemo by using Bailey's eco-location, and using a family of otters to stop the traffic and free Marlin and Nemo from the truck, as well as guiding Hank after they took control of the truck to free themselves and the other fish. All of which she thought all by herself, showing that she is highly intelligent despite her retrograde amnesia causing her to be a bit clueless and oblivious at times.
 * 12) Similar to other amazing and truly awesome comic reliefs, such as Rallo Tubbs from The Cleveland Show, Mushu from Mulan, Patrick Star from SpongeBob SquarePants, Mater from Cars, Donkey from Shrek, Sid and Scrat from Ice Age, and Roger Smith from American Dad, Dory is one of the most memorable comic reliefs in all of Animation and movie in general as Dory has not only made a ton of internet memes, but she steals the spotloight whenever she appears.

The Only Bad Quality

 * 1) Due to her short-term memory loss, she is simple-minded and scatterbrained, and not always very helpful.
