The Reason Zenos.

[Theodric]

Zenos isn't particularly interesting to me. I'd note that there's a big difference between an antagonist and a villain - and Zenos is very much described as the latter.

Worse yet, he doesn't really do anything of note beyond serve as a convenient plot device meant to stall Garlemald and the Ascians so that the Warrior of Light can run about largely unhindered.

For all his talk of the hunt, he doesn't do anything to truly get the Warrior of Light swearing to come and fight him. He doesn't kill the likes of Lyse or Y'shtola when given the opportunity, so it all falls flat when the only person of note he does kill is his father. Who, by all accounts, was a skilled combatant and master tactician - and he really should have seen it coming given the fact that he didn't view him as anything other than a monster due to his behaviour.

Zenos worked well as the antagonist of Stormblood. Then he overstayed his welcome and ended up forcing characters built up for far longer - such as Varis and Elidibus - to stand aside. I'd much prefer to see more Garleans along the lines of Regula - loyal to their homeland and people but possessed of an honourable streak without being defectors.

As for why he's in Dissidia? Meh. Lahabrea, Gaius and Nael are far more iconic to me. Regula too. I'll reserve my judgement to see what Zenos does in the future but so far his track record is unimpressive.
