I've been thinking lately about the voidborn. What do they think about each other? Are they friends, enemies, neutral? Gentleman Cho'Gath's quote,"It's funny isn't it? How your best friend can just blow up like that.", makes me think that he's referring to Kog'Maw. It's just something I've been wondering about.

Eat or be Eaten.

Likely, they're allies because they have the same goal - keep in mind, they come from a world of chaos... A world of chaos depends on conflict, so I doubt you'll see Cho'gath and Koggles sitting down for tea after they destroy humanity.

And where does Zix fit into this bromance?
