The Team Sonic were stuck in the different dimensions. Meanwhile, Symphony saw and met Sonic and his friends because Eggman created Riftbot to rule the world. Symphony had a team called "Team QUARTZ" which is why she is a leader. Sonic met the other team named "Team Bloop" and saw the rifts go by. That day, Sticks met a cycloptibeetle named Debbie, she was a cutest creature that nobody saw. And Symphony and her friends were there to help Sonic stop Eggman to rule.
