Anime is well-known for powering up characters with transformations. Plenty of those transformations have become iconic in their own right: Bleach's Bankai, Naruto's Sharingan, Saint Seiya's God Cloth, Attack on Titan's Titan shifting, Sailor Moon's Moon Prism Power, etc. Among these transformations, Dragon Ball Z's Super Saiyan has to be one of if not the most iconic. Every anime fan and even mainstream audiences know the form, it inspired many power-ups that followed, and it's just an epic transformation in general. It's an icon of anime and pop culture the world over. It would be difficult for anyone to conceive a form change as unique and impactful as Super Saiyan.
