Sega Announces new 2D Sonic title

[Koopaul]

A "sonic friend" is anyone who isn't sonic, knuckles, or tails.
Basically, useless "friend" characters who don't need to be in the game.

Personally, I don't think shadow, rouge, or blaze fit as sonic friends, (and rather, count as main characters) and amy is debatable. As for the Chaotix, they don't count as sonic friends if knuckles is with them.

Everyone else is a sonic friend.

Oh sounds like you're making up crap.
