Marlin

Marlin is the protagonist of Disney/Pixar's 2003 animated film Finding Nemo and the tritagonist of its 2016 sequel. He is the widower of Coral and the father of Nemo and 399 unborn clownfish. From this moment on, Marlin became overprotective, neurotic, paranoid, worrisome, and pessimistic, as he made several practices and conditions for Nemo and himself to follow to make sure they were protected and safe. He was especially paranoid and neurotic about any potential danger that could occur to Nemo, and as such, rarely left Nemo alone due to the traumatic experience of losing the rest of his family to a barracuda attack, and not wanting the same thing to happen to Nemo. However, this overprotectiveness is what puts somewhat of a strain on his relationship with his son, as Nemo feels suffocated and oppressed by it.
