Villains

The Villains are a group of scoundrels from various worlds who seek to harness the power of the Heartless. They are led by Maleficent, and originally had the goal of capturing the seven Princesses of Heart and taking control of Kingdom Hearts, to rule all worlds. After their first defeat at the hands of Sora, they are much less organized, and while they occasionally cooperate on a one-on-one basis, they no longer work in concert and follow their own goals.

Each Villain is usually the boss battle for their native world.
