Never watched Eva. I was a big fan of the Kaiju approach. Eva doesnt own purple/green. Theres plenty of themes people could shout at you. The joker, hulk, riddler, prowler, greengoblin, puffy ami yumi, kang the conqueror, lex luthor, piccolo, aries Shion etc. I think Eva just comes to mind for most right now because there was an IC for it before. I think you should hold onto your original Inspiration.
I love this set and love the colors, but I'd probably only be in if for the monsters XD
