Synopsis:
Players take on the role of a Portal Master, who can control over 30 different Skylanders, including the purple dragon, Spyro, by placing their figurines on the Portal of Power. These heroes are the protectors of an amazing, mysterious world, but they have been ejected from their world by the sinister Dark Portal Master known as Kaos, and now, they are frozen and shrunken down on earth as toys. Due to the lack of magic in the human world, the skylanders are petrified, and only the players of Skylanders: Spyro's Adventure can get them back into their world. Once back in their home world, the skylanders embark on a fantastical journey where they will explore mythical lands, battle menacing, outlandish creatures, collect treasures, and solve challenging puzzles as a part of the quest to save their world.
Plot:
The game starts with Master Eon greeting the young player, who is the new Portal Master, and explains to them of the world of Skylands, which is a world filled with wonder and mystery where the Portal Masters and the Skylanders kept peace and balance so that all creatures can thrive. But Skylands is in grave danger and it needs the help of the new Portal Master. Afterwards, the new Portal Master and the Skylanders meet up with Hugo, Eon's assistant, and Flynn, the balloonist, on the Shattered Island and saved the villagers from a tornado ravaging their town and revealing the return of the Skylanders. As they make their way to the Ruins, Hugo explains to the new Portal Master how Skylands became its current state.
The Portal Masters had protected Skylands for as long as anyone could remember. Master Eon, the last good Portal Master of Skylands, and his Skylanders guarded the Core of Light, which is a machine that enriched Skylands and repelling The Darkness. However, Kaos, an evil Portal Master who attempted to destroy the Core of Light in the past, returned from his banishment in the Outlands to destroy the Core to rule Skylands as its emperor, knowing that Eon has grown weaker with age. The Skylanders fought against Kaos' minions to protect the Core of Light and just as they were winning the battle, Kaos unleashed a mysterious creature that successfully destroyed the Core, causing the Skylanders to be banished from their world. As the Skylanders were drifted farther away from the magic of Skylands, they began to shrink until they reached Earth, where they were turned into toys as a result of that world having no magic and awaited for the new Portal Master to find them. Master Eon survived the destruction of the Core of Light, but became a spirit and couldn't fight the Darkness without his physical body. He then waited for the arrival of a new Portal Master until one finally arrived, which is the player.
After saving Cali from a group of evil Drow warriors, Hugo begins with tasking the Skylanders in recovering the missing Eternal Sources needed to rebuild the Core of Light along with ancient artifacts needed to contain those elements. Kaos soon becomes aware of the new Portal Master and the Skylanders and attempts to stop them from retrieving the Eternal Sources, but fails. With the help of the new Portal Master, the Skylanders recover the missing Eternal Sources with the help of new allies, including a Gillman named Gurglefin, a newly grown Tree person named Arbo, and a sarcastic Undead skeleton named T-Bone. Eventually, the Core of Light is restored, repelling the Darkness from Skylands and driving Kaos back into the Outlands. Despite their victory, Hugo knew that the fight wasn't over, since Kaos still had the very weapon that he used to destroy Core of Light and knew that he would do the same again. The decision was made to take the battle to Kaos in his lair. Using the Core of Light, the Skylanders are transported to the Lair of Kaos where the enemies they faced before lurked before confronting Kaos himself face-to-face.
During the battle, Kaos revealed his most powerful minion to aid him in the fight against the Skylanders, which is the one that destroyed the Core of Light and caused Eon to be in his current spirit state: the Hydra. The Skylanders successfully defeated Kaos, his dark minions, and the Hydra, and he was soon imprisoned inside a forcefield back at the Ruins. After a tender moment between Flynn and Cali, Kaos then promised to Eon that he would keep returning to Skylands until it was his if he was to be banished to the Outlands again. However Master Eon had a more fitting place in mind to banish Kaos to instead. Eon gave Hugo the honor to type in the coordinates to Kaos' destination of exile in the Core of Light, while Kaos is attempting to bargain with Hugo to share Skylands if he was set free. Knowing Kaos and his evil ways, Hugo typed in the final coordinates, sending him out of Skylands to Earth, where he was turned into a toy. Master Eon appears before the new Portal Master, explaining that they may have seen the last of Kaos and the Darkness, but there was still much to do, and that their journey with their Skylanders was only just beginning.
