Rivals

A common type of villain in movies concerning sports, a rival may not actually be an evil person but is in the way of the hero. Many rivals resort to cheating or unsporting tactics, so they could be considered dishonorable.

Outside sports-themed media, a rival can be a type of archenemy who causes problems for a hero but often shares a mutual respect for his or her opponent, whether it's similar appearances, love rivals or just old fashioned childish behaviour, which is common in sitcoms or children's cartoons.
