This add-on makes the mobs in-game fight each other. The purpose of this addon is to see which mob is stronger through a fight. You can make them fight inside an arena or a ring. Just spawn two mobs (or more) and they will automatically fight each other. This idea is from the Minecraft Mod called "Mob Battle Mod".

- This addon is officially discontinued/outdated. The implementation of new features and bug fixes for this addon will be suspended (may or may not change in the future). Angry Mobs! Add-On seems like a viable alternative.
