At the end of Season Three we will know the true threat of the Forbidden Powers and that the standing stones on Mount Thunderstrox aren't just stones but a rocky crown atop the head of some giant, stone COLOSSUS. Clay will have been turned to stone and Aaron will step up as leader of the NEXO-Knights. Merlok 2.0 will be working deeply on trying to get a series of Ultimate Combo Powers that he needs to defeat Jestro and the Cloud of Monstrox. Early on, The Cloud will hit Clay with lightning and he will become the powerful GRAY KNIGHT - a GRANITE WARRIOR. Initially, he will be evil, but he will be turned back by Merlok after having a "western" adventure. When Clay becomes "chaotic good" again, he will excel at fighting Jestro's Rock Monsters. (And, at the end of the season, Merlok will turn Clay human again using the reverse of the spell he used on Debrina Stoneheart, who, we will find out, is Clay's mother, MERGANA - who is also Merlok's sister.) Ava, in working with her computer algorithms, will create a virtual copy of herself - AVA 2.0 - which, at some point in the future, she will able to use to assist Merlok 2.0 in the computer itself (and finally provide Ava with some quality conversation.) Aaron will learn that he can be a leader and it reinvigorates him. Macy will be worried about Clay and about her place in the Kingdom does she really want to lead Knighton some day? Lance, Macy and Axl will step-up as well as Jestro and the Cloud of Monstrox find the final six Forbidden Powers, lock then into Mount Thunderstruck and free the STONE COLOSSUS which will march across the realm - headed for Knightonia - destroying everything in its path. Eventually, Robin will finish his super-secret project: the construction of a giant, castle-shaped rocket - built from the remains of Merlok's Tower in the King's Castle. Robin will also build the MEKLOK! A Mech made for Merlok so that he and Clay together can destroy the Forbidden Powers in the crown of the giant Colossus. This is what they'll need - along with the firepower of the other Knights and the Fortrex - to finally stop the Stone Colossus, destroy the Cloud of Monstrox, and capture Jestro (can he ever be trusted again?) At the end of the season we will tie things up, but we will also discover there is a "ghost in the machine" Monstrox!
