4. Ernesto De La Cruz (Coco)
Ernesto is the most realistic of all the villains on this list. Ernesto lies about being Miguel’s grandpa, knowing it is a falsehood. It’s hard not to hate Ernesto when you find out he murdered Miguel’s actual grandfather and then claimed all the credit for Miguels grandfather’s musical achievements. The delusion may be motivated by simple envy, but that’s not enough.
