Julyan vs Zenos

[Catwho]

There is a hypothesis, long before ShB came out, that Godbert and Julyan were modern incarnations of two of the Twelve, and that's why they are so absurdly overpowered.

Since our 24 man raid this expansion is finally going to answer a lot of remaining questions about the last of the Twelve, we'll find out if there's any truth to that hypothesis.

I don't think it's 'canon' it's just a gag a lot of Japanese media have, you see it a lot in anime where someone is much weaker than the protagonist can bonk them into a wall or something. If they'd fight Zenos in a serious setting they'd lose most likely.
