Third-last Dino Super Charge episode today, and things are building toward the big climax. Not a bad episode, though I don't really see the point of bringing back Sledge as the big bad instead of keeping Lord Arcanon, since the latter was the one that Heckyl had a vendetta against. Anyway, it's good to see Heckyl starting to become an ambiguous ally.
The plot structure was a little odd. They need to make a new Zord because most of the Rangers are turned to stone, but then the Rangers are freed before the new Zord debuts, so that kind of obviates the need for it. Also, it's weird that they had the Megazord battle before the big battle against the normal-sized monster.
While we're at it, I wonder about the mechanics of how a giant monster can blow up but then return to normal size and fall to the ground. Is the giant monster some kind of shell that forms around the normal-sized monster? Or is it that maintaining the giant size is a strain and too much damage or energy drain undoes the effect, causing the monster to shrink back to normal, sort of like an inflated balloon losing its air? With most monsters being shrunk and destroyed at the same time, but some of them durable enough that they're shrunk and not destroyed?
