S04:E38 - Iron Grip

Clay is locked in the Command Center, as a statue.  Merlok can tell he’s angry at the world, even through his granite skin.  Merlok 2.0 understands: Clay’s incensed because Merlok lied to him about his mother.  Merlok uses a powerful spell to reverse the stone in Clay’s body. Clay becomes human again, but doesn’t feel like himself.  Macy comes in and begs forgiveness and Clay says it’s not her fault.  It’s MERLOK’s fault.  What is going on?  Merlok finally must explain Clay’s past: you see, Clay has tremendous magical ability.  But everyone in Merlok’s family who has had that ability has been driven mad.  Merlok tells him, Ruina is his mother. Her real name is MERGANA and she is Merlok’s sister.  She turned evil and Merlok took Clay away to protect the boy.  Merlok then used a powerful spell to turn Ruina into a statue.  She was unearthed in “Mergana’s Garden” by Jestro’s minions.  And now she’s back. Merlok wanted Clay to be a knight. But being the Gray Knight has tapped into something magical in Clay…and now he’s sort of out of control. But no time to lose…the FINAL Forbidden Power is in play and it’s the most powerful one yet: AWESOME ANNIHILATION!  The final FP Jestro and the Cloud of Monstrox need.  They find it near the town of Strongheim and are able to use it to totally annihilate the town.  “Even Knightonia can’t stand against the Forbidden Powers we’ve gathered!” says the Cloud.  Meanwhile, the Knights are trying to respond to Jestro, but Clay is lashing out with his raw magical abilities.  Merlok 2.0 finally must cocoon him in the Command Center during a magical showdown.  At the very end of this episode, Jestro locks the last Forbidden Power into the Standing Stones at Mt. Thunderstrox.  The Knights arrive in the Fortrex, having finally triangulated where Mt. Thunderstrox is.  They all see what happens as the Standing Stone Crown powers to life and the GIANT COLOSSUS of ULTIMATE DESTRUCTION forms, then rises to its full height.  The Cloud of Monstrox goes INTO THE COLOSSUS, bringing it to life and imbuing it with power.  The Colossus now has the evil face of Monstrox.  It starts to stomp across the land as the Fortrex races off to warn the kingdom (and stay ahead of its huge feet!)
