Tailsmo (Tails and Cosmo) were an official couple.
Tailsmo and Chaream
There are no official Sonic couples.
No. There is no proof that there are couples in Sonic Next-gen. Although,there's this whole Sonelise thing, it's not true. Sonic SAVES his friends from danger when he can. Just because Sonic saved Princess Elise of Soleanna that doesn't mean he loves her or any other girl he has saved so far. Making couples out of these characters only deals destuctive blows unto SEGA's fan rate and that's just wrong.
Chaream
