Don't worry Sun! It's an alternate story, so that might be a different you! I mean, ever since ORAS established different realities, you don't have to go though another adventure. "Ultra" Sun will! After all, ever since the Ultra wormholes incident, there are some rifts of space and time, how do you think you were able to go to the "Alternate World" for a Cosmog? Gotta catch them all son.
