Kaos

"Behold! It is I, KAOS! And as you can see, I AM AWESOME!!"

- Kaos

Kaos is the main antagonist of the Skylanders video game franchise, although his role is often downgraded to secondary antagonist by other, stronger villains, such as his mother, the Golden Queen, and The Darkness. He is the archenemy of the Skylanders.

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.

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 destroyed the Core, the Skylanders and the new Portal Master transported to Kaos's lair, where they underwent a long battle against Kaos, his dark replicas of the Skylanders and the infamous Hydra.

After a long fight, the Hydra is driven 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.

Skylanders: Giants
After being banished to Earth, Kaos became unfrozen due to his status as a Portal Master. After being contacted by his butler, Glumshanks, he used a Portal of Power used in a toy store display to return to Skylands, but not before taunting the Skylanders still trapped in toy form. Upon his arrival, he landed in a very ancient part of the world and discovered the remnants of a civilization that ruled Skylands over 10,000 years ago; a race of magical and technological beings called the Arkeyans. Kaos unintentionally reactivated one of their robots, the Arkeyan Conquertron, and quickly learned that if he could acquire something known as the "Iron Fist of Arkus", he coud not only reactivate the entire army of Arkeyan robots but also command them.

With that kind of power, Kaos would pretty much be unstoppable and it's up to the new Portal Master, the Skylanders, and the Giants to stop Kaos and the Arkeyans. After being defeated once again by the Skylanders, Kaos and Glumshanks retreated back to their castle, only to be confronted by Kaos's Mother.

Skylanders: Swap Force
Kaos concocted a plan to evilize one of the Ancient Elementals in the Cloudbreak Islands so that when the Elementals perform their ritual in replenishing the magic of Skylands, they will instead spread darkness. The evil Portal Master uses Evilizer devices to turn innocent creatures into darker versions of their former selves. Helping him on his plan is Kaos' Mom, who is revealed to be a dark Portal Master like her son.

Skylanders: Trap Team
Using his newly constructed Frequency Madulator, Kaos freed the villains, mainly the Doom Raiders, from Cloudcracker Prison at the hopes of them helping the evil Portal Master fulfill his latest plan in ruling Skylands. However the strong elite of villains had other motives and cast aside Kaos in favor of following their leader, the Golden Queen. The Golden Queen allowed Kaos and Glumshanks to stay, only to come up with a plan of her own, stating it's "solid gold". As dissent grows in the ranks, Kaos, sought to take back control, commences "Operation Sabotage". He intervened at Phoenix Psanctuary to sabotage Chef Pepper Jack's plan on stealing the Phoenix Chicken, but backfired, his smoke rocket allowing Chef Pepper Jack to get away with an egg from the Phoenix Chicken.

When attempts of winning over the Doom Raiders failed, Kaos lashed at the Golden Queen for her ultimate goal of having all of the gold in Skylands over being its ruler. The evil Portal Master foolishly challenged the Queen to an "Evil-off" with the winner taking all and the control of the Doom Raiders and Skylands. Unfortunately, it ended rather quickly and poorly for Kaos as the Golden Queen simply turned him to a gold statue.

Having lost Glumshanks and his hideout to the Doom Raiders, Kaos was forced to make a truce with the Skylanders for help in defeating the strong villains who betrayed him. After acquiring an Information Squid from Mags' home village in Rainfish Riviera, the heroes wanted to know why the Doom Raiders were obtaining Traptanium. Eventually, the Information Squid turned out to be Kaos who soon turned into an unlikely alliance with the heroes, but it won't last long until the Golden Queen is captured. With Kaos being the only lead to where the Doom Raiders were, he lent his assistance by telling the heroes the whereabouts of Dreamcatcher and later accompanied the Skylanders to the Wilikin Workshop where he created the Wilikin.

Much to his shock, Kaos found his workshop under the control of Dr. Krankcase and helped the Skylanders infilitrate the factory. He became captured by the mad doctor, who was ordered by the Golden Queen to retrieve Kaos in order to travel through time for their plans. During the Skylanders' battle with Dr. Krankcase, Kaos was taken away by Wolfgang to Time Town, where the werewolf began using Kaos's power to mess with time. The Skylanders managed to rescue Kaos, but Wolfgang escaped into the future.

After the Skylanders defeated the Golden Queen, Kaos and Glumshanks took control of The Ultimate Weapon. Glumshanks warned him that too much Stinkocity was very dangerous, to which the dark Portal Master ignored, saying that Traptanium is the "ultimate power source", having a much different effect on a Dark Portal Master. Kaos powered himself with the combined Stinkocity and Traptanium, turning into Ultra Traptanium Kaos. With this power, he was able to see the new Portal Master through the fourth-wall and planned to not only conquer Skylands, but also pull the new Portal Master from their world and trap them in Traptanium. The Skylanders infiltrated the Ultimate Weapon to face Kaos, who underwent a fearsome transformation to battle the heroes. After a long battle, it ended in Kaos's defeat and capture. During the credits, Kaos complained about how the player had an entire army (the developers) helping them when all he had was Glumshanks.

Skylanders: SuperChargers
Despite being captured during the previous game, Kaos was far from reformed; in fact, he was merely biding his time until he could gain his powers back and take revenge (a fact revealed in the Skylanders comics). Once he reclaimed them, he led a preemptive strike against all of Skylands, imprisoning any potential threats to his rule and somehow severing the link between portals and Skylands. His crowning achievement, however, was the assembly of the Sky Eater- a massive sky station that literally ate the sky, which was powered by The Darkness. Glumshanks had doubts concerning the Darkness, but Kaos (ever over-confident in his abilities) believed the substance was harmless, even after it gained sentience.
