(POSSIBLE SPOILERS) Zenos Build: Mount?

So, I couldn't find anywhere else to try and ask this here, so...

Basically, I was interested in trying to create a build based on Zenos; I've already got the jobs (Samurai and Reaper) figured out, along with the general armor/glamour figured out, but there was one small issue left: a mount.

Put simply, I know that Zenos technically had an unlockable mount in Stormblood - the Magitek Predator - but I was thinking more along the lines of a mount that Zenos himself would use. Technically he did have Shinryu at the end of Stormblood, so I was thinking a similar-looking dragon mount would suffice; however, I can't figure out which one to go for.

Simply put; out of all the mounts available in-game, which mount would look the most fitting for a Zenos cosplay?
