Solution 9 - Unfounded Speculation!

[Cleretic]

A pretty solid theory I've seen on Twitter for that red sign in the Arcadeon that people were fixated on: What if it's the Armodullahan from FFIX?





It's got the right claws and horns, and if you approach it from that angle then the weird mass of lines in the middle can read as a pretty decent approximation of its face maybe biting down on something.

Of course, the Armodullahan's a pretty 'nothing' boss from FFIX, so if that's true then it's also a guarantee that it's a 'middle of the first tier' filler fight, like Catastrophe or the Hippokampos. ...which, in turn, means that we can intuit jack squat about its actual story, because the Armodullahan's hardly a stretch to fit in to an FFIX-inspired expansion with a high-tech corner of it.
