Kamen Rider Amazon New Strand Haruka Mizusawa Amazon Origin Form. I redesigned the origin form of Haruka for my fan made comic book. I didn't really like is original origin form in the show because it did not look like the rider form (alpha's origin form looked like is rider form). So I tried to mimic the main rider form in terms of the side ears and the antenna. Also stated in his picture bio, unlike the show version, he grows like a normal person and ages like one. I even made his child form version when he changed into it when he was a little child (from birth to age three, his human form was formed first but his amazon form manifested and lasted till he was in his pre-teen age). I was also trying to make the child form amazon look cute as possible with the big eyes and smaller less developed spikes. I do like how it turned out.
