March of the Colossus
The Cloud of Monstrox is inside the Stone Colossus and it now stands in front of Knighton. The students of the Knights Academy are mobilized, the King and Queen are on the defense and the Nexo Knights are ready for the showdown.
- Clay referenced the Nexo power Achilles Heel as a pun by controlling the rolling fortrex and, coincidentally, hitting the Colossus’s heel with it.
- This is the last episode of the entire TV series.
