Two amorphous magic things inside armors; quite different ones, but both great!
I love Sir Lime! HOW have I never seen a slime knight before? Monster knights, plenty, especially skeletons, but slimes are such an early game monster- I'm glad he's moving up in the world, standing up for his people! If he can stretch and bend that sword it'll be amazing.
Rainbow Knight looks like a celebrity, and probably is one. According to your other posts, there's a whole human squeezed in those spindly joints, and I'm both shocked and slightly sad he's not a magic armor, but he's cool too!
