I dont know about anybody else but When i beat Xenogears i only got to the fourth combo, sad I know... it gets worse i didnt know how to use the combo command, but i did know how to use combos. Any way. There was a really hard boss on there for me. I dont know his name but he was that Floating orb gear guy that was in the shield generator cave next to Barts home town. (i frogot the town name.)
