Somehow I skipped this video, oh well.

I really like how capcom set up the mood this monster. It's just so weird and mysterious and the way it falls and reveals little of its real body is really well executed. Given we have already seen the undead dragon abomination that is Gogmazios we might even see the alien-looking dragon with tentacles in the future!

I'm actually not even sure where the roar comes from, but I'm sure it's not from the tentacles and starts around the main body. It either comes from the holes on top of it or from underground. At 9:58 you see that it raise itself up the bit and the roar effect seems to be from above.
