Sonic Prime (2022) Flashbacks

After Sonic urges him to find a solution to the matter, Nine suggests draining the sliver of energy from Sonic to restore the Prism, but warns him that he may cease to exist. Despite this, Sonic agrees, siphoning his Prism energy and destroying the reactors on his gear. With the Prism fixed, the Chaos Council double-cross the group to take it, but Sonic lures them into quarrelling over who should get control of it, allowing the denizens to catch them off guard and banish them into the Void. With a gateway to Green Hill open, the Shatterverse denizens part ways with Sonic before helping him reach the gateway. Running low on time, Shadow carries Sonic to the gateway before he fades from existence, returning him back to the battle in the cave moments before he shattered the Prism. Happy to see his old friends and arch-enemy again, Sonic cooperates with them and they defeat Eggman, before Shadow arrives and teleports himself and the Prism away to an unknown location, foiling Eggman's plot. Later, as Sonic has a picnic with his friends and plans to recount his adventures through the Shatterverse, a large shockwave occurs, and huge unknown object appears, sending Team Sonic into battle once again.
