Thought the Megazord fight was pretty good. I really like how Sanzu River went crazy and the Moogers increased during Xandred's power struggle.
Had Turbo/Space flashbacks when Ji said "Black Box." >_>
Good plan from Octoroo to find out the sealing power symbol (and make Jayden suffer). I figure they just wanted to make him more kid-friendly (not that there's anything evil about the original costume in the first place)... But as long as he's out scheming, I don't really care. Liked how Archnitor plotted to become the new King as well.
I love that the show is going somewhere and building up to a season finale similar to the Fox Kids days. We've had enough years of the head villain waiting all year for the big boss to arrive or whatever. 5/5
