Patterns for Lavos's Final Form

I'm sure some others have noticed this, but has anyone recognized the patterns for his final form? And if so, when?
For those who dont know what I mean, he uses Temporal Shift often, which changes the background image. There are 5, one for each Era. And each Era has it's own attack!

Prehistory: Grandstone / Ultimate Physical Attack
Antiquity:From what I see, nothing. If anyone know he does an attack in this period, please tell me.
Middle Ages (Magus's Lair): Demon Star / Halves HP
Present: Diabolic Whisper / Random Status Ailments
Future: Dreamreaver / Ultimate Magical Attack

So, has anyone else noticed these, and how long did it take? It took like my 5th battle, I was like, "Hey, he only uses Grandstone in Prehistory!" And I worked it from there. XD

I noticed that on my first fight against him, where he kept using Grandstone, then he shifted and I kept waiting for him to use Grandstone then I figured out the pattern. I just didn't know his other moves for other eras.

I think Antiquity should be Heavenly Tears

ive nosted that on my first play through

Same here..

in antiquity he slows the party, just thought i'd mention that

yeah i notced its attack patterns since he shows a pic of the enemie
