I can see where you're coming from with Palom and Porom and Edge (their personality and roles in the story are clear, but they're not as deep as other characters from other FFs). But you can't tell me that Golbez is "bland." His tragic past and guilt-ridden personality, yet his strength and determination to do what's right whether it's defeating Zemus or going back to earth to save the people on it is far from bland and boring, especially considering he's a villain for most of the original FFIV.
