In the pics where you see four smaller based creatures/vehicles, those are called morphers. They are kinda like Voltron/Power Rangers in that they combine to create a larger monster to fight with.
Anyhow, first up are the GUARD monsters. A good number more monsters then the other forces since starter set for my daughter had it, as well as the expansion we bought:
I will post the Lords of Cthul and Terrasaurs pics throughout the week as I get done cleaning up the photos to upload properly.
