Rutabaga

Ah yes, another creature to make me anxious when flying, and a really goofy looking one no less!

I'm going to be honest in saying that the corrupted crest concept alone kind of sells the concept to me. Having a more combat-oriented pterosaur would also be nice, especially for its size.

A roach does feel unreasonably fitting for Extinction (and I guess Aberration as well, although that vote has obviously come and gone). I'd be fine getting something like this, but as a shoulder pet, it'll definitely be fighting an uphill battle.

I have already come to the conclusion that it'd be really cool for a Sauropod (/ prosauropod) to be chosen for Extinction, and this is definitely a long-time frontrunner in that regard. I don't know if I necessarily want one that's bigger than the Titanosaur though from a progression standpoint (though I wouldn't mind it simply being slightly smaller overall, yet taller due to a different neck orientation). I do like a lot of the ideas though for this, let the slow and gargantuan creature be an absolute menace to make up for it. They should be able to say "this is my spot and you have to respect it". The idea of having element influence its appearance too is a nice addition too (a concept that I've seen a couple submissions mirror, like that pterosaur that builds up a corruption aesthetic, both ideas really fit the visual theming of the map).

You know what? I think Extinction could do with a sauropod, and this concept both portrays a really nice to control sauropod, along with a very amusing taming method. We need the Guitar Hero tame! Even if it doesn't win, I would love to see it as a mod.
