While they're all unique, I feel like my top 3 share a general look about them, but the '93 just stands out from the pack and not in good ways. All the other designs have an evil, vicious look to them, but that one is so soft and non-threatening.
Agreed. It's odd too, since Heisei is my favorite era in terms of designs. I think Toho and their artists absolutely killed it on Godzilla and most of his foes, but they dropped the ball on the ol' bucket of bolts.
