>>44377174You know how the Canalave library mentions that "the power of defeated Giants infuses this plate"? Apparently, arceus killed or defeated many giants long ago long ago and far away in space.
Ultra beasts come from far away dimensions, ultra spaces. They all have very diverse typings as well. Is it possible that they were the giants that Arceus killed for the plates?
Still not convinced? Well, remind me again what was the creature created by Aether to kill the UB's? Type: Null. And what is Type Null based off of? Arceus. The RKS System is literally a simplified form of Ar-ce-us.
