I really want the source of it. Probably some kind of art/guidebook thing. There’s also another one which I found in VSBW of all places. アルティメットフォームは、どうやらクウガをはるかに上まわるパワーをもつ最強戦士らしいの。だから、もしアルティメットフォームが悪の戦士だったら、地球がめつ亡してしまうかもしれない! The Ultimate Form is apparently the most powerful warrior in the world, far more powerful than Kuuga. So, if Ultimate form is an evil warrior, the earth may be doomed! On a 01 related note, Horobi has a nice speed feat in the Reiwa the First Generation movie while not even in Rider form
