How big is Bahamut?

[Frederick22]

This seems much more likely to me and is still terrifying. OP, I think, as you stated, that your fault was in the assumption of the proportional size of Dalamud to Menphina. Keep in mind that Dalamud is a construct of the Allagans and while they were incredibly advanced, I find it hard to believe that they were able to build and launch a man-made satellite the size of PA. Even building an ~3-4 mile wide satellite is an incredible feat.

So you are saing that he got bigger on the time he was on dalamud? that doesnt make sense, he was always that kind of big. Its easy to know his side guys, go to T5, look for images of Bahamut, then make your calculations xd

As we know Bahamut is a primal but there is the question of was he ever a dragon (and dragon only)

Yes. He was one of the first brood (I'm assuming that makes him one of Midgardsormr's children); the Meracydians prayed to him and gave him new form as a primal. The Allagans kept countless dragons captive and tortured them so their constant cries for help would keep him from returning to the aether, therefore allowing them to imprison him in Dalamud.

All in all, it's truly a sad story. Bahamut has all the reason in the world to be exceedingly pissed off; the problem is that his rage is misplaced by the span of hundreds of years. Personally, I saw killing him as freeing a completely mad creature from the grip of his own rage-induced insanity. We did him a service as much as we did Eorzea.

Funnily enough I actually did a visual comparison of player size verses his claw;

That tiny dot that you probably can't even see? That's a Miqo'te.

"Let us fight a full sized Bahamut Yoshi!" lol
