5. Marlin - Finding Nemo
Marlin is the complete opposite of Dory, but that's why we love him too. He's reliable. He's constant. But more importantly he is completely motivated and fuelled by his love for his son. What better motive do you need to do anything than love? Sure he's stuffy and overbearing at times but it's just because he's scared something will happen to his son, and justifiably so! They live in the sea, predator's are everywhere and Marlin's wife was eaten before littleNemo could be born, I think that gives Marlin a Get Out of Jail Free card when it comes to protective parenting.
