sworn enemy

Lifelong bitter rival

A sworn enemy is someone you have vowed to oppose or defeat—an adversary bound by deep, enduring hostility rather than circumstance.

The phrase suggests enmity that won't fade: Batman and the Joker are sworn enemies.

Often used with dramatic or humorous exaggeration: Broccoli has been my sworn enemy since childhood.
