This page focuses on the upgrades for the 9 main characters.
Upgrades[]
All of the familiar upgrades make their return from the previous titles as well as new upgrades. They can be found in both Adventure Fields and Action Stages. For the Mystic Melody upgrade from SA2, which is exclusive for all characters, it is not only used for finding the Lost Chao, but it's also used to unlock new pathways and areas in stages, in which it's mostly required to advance through the levels. It's also worth noting that once you find the Mystic Melody with any character of each of the three stories, their teammates will also obtain it.
