Nothingness

Bestiary Description
Spike: Nothing? You fought...nothing. Rainbow: It was kind of terrifying Spike: You know, over the course of this weekend you've fought eggs and pinecones and tumbleweeds and all sorts of other weird junk. But this? This is NOTHING. It's literally nothing. It doesn't exist, but you fought it anyway. This takes the cake. This is officially the Weirdest Enemy Ever.
