i was dissapointed about enuos backstory too. he seemed really important but he was barely mentioned. im sure the storyline for bringing him back will be good.

about X-death. i thought he was just something born in moore forest but i bet i've forgotten something because i doubt it would be that simple.

he may not be as powerful as omega and shinryu because in a library in the N-zone it says that not even the original wielders of the legendary weapons could defeat them. but i have a feeling that enuo will be the hardest boss on the game even if he isn't the most powerful storyline-wise.
