Archrival
Where a person or entity has multiple rivals, the most significant one may be called an archrival. In fiction, it is common for a recurring heroic character to have an archrival or archenemy to serve as a foil to the hero, but an archrival may also be distinguished from a nemesis, with the latter being an enemy whom the hero cannot defeat (or who defeats the hero), even while not being a longstanding or consistent enemy to the hero.
