Look carefully at which part of your post, better yet which villain I am referring to. I fail to see resemblance between Golbez and Darth Vader, perhaps appearance wise, though even then not quite. Golbez was never truly a villain, he was being manipulated by Zemus from the very start, and in a manner where he could not gain control over himself and his, in this case, Zemus's actions. Golbez is not evil and he technically never was, he is in fact calm and a kindhearted person.

You could say Anakin was also manipulated by Palpatine, though not in the same manner, not even close. After all, all of his actions, his downfall, were in the end his own doing. Out of all FF characters the one that resembles the most to Darth Vader is most definitely Gabranth, how you made connection to Golbez is beyond me.
