Mata Nui is alive once more, but still trapped in endless sleep.

The Toa travel to Karda Nui, the core of the universe, to finally awaken him from his slumber. When they arrive there, they discover that Makuta's Brotherhood has invaded the core and is using shadow leeches to transform Matoran of Light into evil Matoran of Shadow.

Both the Toa and the Brotherhood of Makuta must work together with their Matoran to win the battle in the skies!

Connect the Matoran sets to the back of the larger models so heroes and villains can work together with their new allies!

The countdown has begun, as the Toa battle their greatest foes. But can they awaken Mata Nui in time before all existence ends - and if they do, will any of them escape the unleashed power of the spirit-storm?
