mortal enemy
Deadly lifelong adversary
A mortal enemy is an enemy so profound that only death can end the conflict—each side threatens the other's very existence.
The phrase often appears in dramatic or hyperbolic contexts: Batman and the Joker are mortal enemies.
In casual use, it can describe any intense rivalry: She considers her sister's ex her mortal enemy.
