[Lord Benendearu]

This was indeed one of the lesser episodes of the Dino Charge seasons. It felt like a complete filler that didn't add anything to the overall series.
The whole bully thing felt like a recycled version of the "Bully for Ethan" Episode from Dino Thunder.
And the villains losing their memory in the end was too contrived and averted what could have become an interesting plot twist. I really would have liked to see where the series would go if the villains attacked the Ranger's base so early in the series.
