Krelian is best developed villain in Video Games history. If anyone has played Xenogears you will know this. Not only does he have a stylish look; but he is also wise and smart. Quite in fact he is the guy pulling the strings over the dozens of powerful villains in the Xenogears world. His story is tragic. He was once a noble man in love with Sophia. When Sophia sacrificed herself to save his life a well as Lacan. He began to develop sorrow. Krelian wondered why "God" would allow something like that happen to Sofia. He then came to the conclusion that he would find God...and that if there was no God he would create God. In the end...he actually accomplishes his goal.
One of those villains that you completely understand why he went nuts. Makes you hate him because of the way he manipulates everything and everyone: including powerhouses such as Grahf & Miang. And at the end of the game he actually gets what he wants. Not many villains can put "Winning against PIS/Jobber Aura/CIS" in their resume.
Krelian is the best. But sadly only those who have played and understood Xenogears deep story will aknowledge what I'm talking about.
