Elijah said: After seeing it the first time, i could never unsee how much the Spada resembles a VF-25,
That's just one part of it. Since the VF-25 was a Macross creation, it was designed by Shoji Kawamori who created most of the designs for Macross. He also created the designs for Aquarion. Therefore, the resemblance you see isn't passing-it's his style.
