Heroes are special mice that wage battle against the enemies in an attempt to claim land.
Each hero lives in a building that can be moved around the village, but not removed. Visiting this building allows you to upgrade the hero's weapons and shields.
You can select up to 4 heroes to fight in each battle (fewer before you have found the first 4). Following winning a battle, the hero must rest for a period of several minutes before fighting in another battle (longer if the hero was knocked out).
The heroes are:
- Arthur the Brave
- Robyn the Archer
- Dr. Spark the Wizard
