Akira Toriyama’s Dragon Ball stands tall as one of the battle shonen genre’s standout anime. However, after four decades it continues to evolve, influence new series, and surprise its devoted fans. Dragon Ball is more popular than ever and one of the greatest factors in its ongoing success is its ability to create new and exciting transformations for its heroic characters. Anime often distill a character’s improved strength into a flashy transformation that becomes the new milestone for this hero to match. Dragon Ball sets this precedent early on in its run with its famous Super Saiyan transformation. However, this goes on to become the first stage in a graduated tier of strength. Dragon Ball follows a set pattern for most of its run with predictable upgrades like Super Saiyan 2, 3, and 4.
