So it appears that we have a fully formed White Diamond sized Pink Diamond (probably evil evil cause she has the constipated face), Era 1 Evil Lapises (damaged since their eyes are all mirrory), Giant Evil Centipeed (dunno what that is, looks like some corrupted gem or even an alien pet of Evil Pink), Aquamarine Offcolour (in a business suit), Watermelon Steven Evil Fusion (probably a creation of Evil Pink) and...sigh, Jasper as the villains.
Really Jasper, you cant just not be a villain. I guess thats one way to have new villains in the franchise...even though we still dont know who made the Gem species which should be the actual villain.
