Enemy is the full form of the word enemy. It has many meanings, including someone who hates another (and vice versa) or someone who attacks another.
opponent, attacker, invader, rival
I think that it would be an enemy
Nemesis .
YOu could also call an enemy a fiend or an opponent, hope this helps :)
The word meaning "someone who is disliked by another" is spelt enemy.
I believe the title is "Enemy Mine".
