Kaos

"My head is awesome, I tell you! Fear it! Fear my GIANT FLOATING HEAD!!"

- Kaos

Kaos is the main antagonist in the Skylanders video game series, posing as the archenemy of the Skylanders. His role as the main villain in the 3DS versions are usually acquired by other antagonistic characters, Hektore and Captain Frightbeard.

History
Before he became evil, some say that Kaos was born a prince. But after years of suffering insults about his ugly looks and bad smells, he kicked his father in the widdershins, gave up his royal name and headed out into the wilderness along with his faithful and equally ugly butler, Glumshanks.

Afterwards, Kaos came across the Core of Light, the device that protected Skylands from The Darkness. The evil Portal Master attempted to destroy the Core to rule Skylands, but was stopped by Master Eon and the Skylanders. Despite his defeat, Kaos hasn't given up on attempting to destroy the Core of Light and ruling Skylands under his rule.

Skylanders: Spyro's Adventure
After being banished to the Outlands, Kaos returned to Skylands in another attempt to destroy the Core of Light. He summoned his evil forces, who immediately began losing the battle against the Skylanders. However Kaos had a secret weapon and unleashed a Hydra that succeeded in destroying the Core of Light, banishing the Skylanders out of Skylands and causing Master Eon to become a spirit.

With the Core of Light gone, Kaos immediately began his rule over Skylands, but soon caught the attention of the returning Skylanders and the new Portal Master. Attempts to stop them using the Eternal Sources failed, and Kaos retreated back to the Outlands when the Skylanders successfully repaired the Core of Light. Knowing that Kaos still had the very weapon that destroy the Core, the Skylanders and the new Portal Master in his own lair, where they underwent a long battle against Kaos's dark replicas of the Skylanders and the infamous Hydra.

After a long fight, the Hydra is drived away, and Kaos is captured by the Skylanders and imprisoned briefly at the Ruins. There, Hugo banished Kaos to Earth where the evil Portal Master was turned into a toy and soon tormented by a dog.
