The Sheep are a group of herd animals, who live in the Animal Farm and act as minor protagonists in the story, The Animal Farm. Though, they are featured briefly in the Non-Disney Villains Tournament, the Sheep make their fully appearance in Heroes vs. Villains War.
Non-Disney Villains Tournament
The Sheep, along with the rest of the Animals, are featured in the Battle of the Animal Farm, trying to drive out the forces of Mojo Jojo. When they actually finish them, the treacherous Dolf convinces the Animals, including the Sheep, to turn against Napoleon, so they might get retribution for his harassed actions. The Sheep are not featured in the later stages of the war, marking their only depicted appearance in the battle.
