Sonic Prime Season 2 enjoyed a multiverse-shattering summer debut, complete with a few twists and turns. SEGA fans saw Sonic tested like never before, making him question his own destiny. He did need to mature up a bit, but luckily, he had friends around in the ShatterVerse to help him try to repair the fabric of space and time. This led to Sonic trying to recover the shards from the Paradox Prism.
