hated ⇐ hostile ⇒ unfriendly

In World of Warcraft, hostile can mean a couple of things:

1. Hostile usually refers to a Player, Pet, NPC, Town, City, or Zone of an enemy faction to your character (Alliance or Horde) as opposed to being Friendly or of a Neutral faction.
   Additional notes:
   • When you click on hostile mobs or NPCs, their name and highlight will be red. Most hostile creatures will attack your character when you get within a particular aggro or major threat range.
   • Most mobs in hostile zones will be hostile.
   • Neutral mobs or NPCs will turn hostile when attacked.
   • You cannot talk to hostile creatures.
2. Also the Reputation Level just below Unfriendly and above Hated.
3. 3000 reputation points inside of being hostile.
