I'ma get this image out of the way before the traditional original this and Dex's ref were based on.

Yes, on a whim, when making a new account, the ref meant for Zax was handed over to Dex! This is why my old refs had a quote-unquote "blue glow" to them, it was originally the shading for Zax! This is also why when you see Zax in the future, he will still be a cat, to differentiate Zax from Dex!
