The Reason Zenos.

[KageTokage]

I kind of agree with the previous notions that Zenos is most likely just being used as a catalyst to turn Zodiark into an active threat despite the Rejoining not yet being complete.

How that ends up happening is anyone's guess, but I kind of hope he ends up becoming something beyond simply tempered and more an avatar of the primal so we can actually get his perspective on the events that have been transpiring.

No, what we fought in the Menagerie was him testing out controlling a primal for himself... and he "offed himself" knowing what his power was capable of.

I honestly never got that impression from any of his dialogue.

It sounded more like he was genuinely resigned to death and satisfied after having gotten his big battle with us and only realized he could cheat death like an Ascian after the fact then decided to make the most of it.
