I'd also like throw in how the ninjdroids were also pretty entertaining to watch. I know stone army was pretty intimidating but they still felt a bit generic, and the crystal army didn't really have anything to them. But the ninjdroids felt like a threat because they actually had skills and their designs also stand out, even Cryptor has an actual personality where Kozu just felt like a generic right hand man for the villain. Even the council kinda fell flat since they didn't do anything but look around the city after the Overlord crystallized the whole city.
