archenemy
The worst or most important enemy of a person, group, or nation; a main opponent.
In der Geschichte waren Rom und Karthago erbitterte Erzfeinde.
In history, Rome and Carthage were bitter archenemies.

The word consists of the prefix 'Erz-' and the noun 'Feind' (enemy). The prefix 'Erz-' intensifies the base word and means something like 'chief' or 'most important'. You can also find it in words like 'Erzengel' (archangel) or 'Erzbischof' (archbishop).
Für den Detektiv war der Professor sein интеллектуаeller Erzfeind.

'Erzfeind' (archenemy) is often used with a possessive pronoun ('sein Erzfeind' — his archenemy) or with the preposition 'von' (of) to clarify the relationship.
Der Superheld kämpft gegen seinen Erzfeind.

The word is often used in fictional contexts such as books, films, and comics. But it can also be used figuratively for major rivals in politics or sports.
In vielen Geschichten hat der Held einen schlauen Erzfeind.

friend / boyfriend
'der Freund' and 'der Erzfeind' are strong opposites. A friend is someone with whom you have a good and close relationship. An archenemy, on the other hand, is not just an enemy, but the most important or worst opponent. 'Freund' fits trust and closeness, while 'Erzfeind' fits strong conflict and opposition. 'Erzfeind' often sounds more dramatic than simply 'Feind'.
