proto zero means it’s prolly the original wing zero, It is mentioned somewhere that one was made by the scientists before Quatre Raberba Winner made the one thats seen in the show.

Luckly for me the girl im interested in loves anime and really likes it when I show her my models or share my anime. So the models are less embarrassing
