Tetsuya has revealed that these "gods" are actually gears from prior games. One is Brigandier, the gear of Bart Fatima from Xenogears and the other is E.S. Dinah from Xenosaga.
I sadly haven’t played much of Xenogears I have the ROM on my computer because it wasn’t released over here. Oh, and the Dinah that was KOS-MOS’s E.S. Robot in the Xenosaga series. That’s pretty cool Darkil I never knew that.
