Not all the time. But in my opinion, (I am a Sonic Fan, and I like him beyond your imagination!) they are totally unbeatable as a team! Sonic has a Hyper Form were he's invincible, but I think it doesn't last that long. I think theres such thing as Hyper Shadow, and there is Hyper Knuckles, but he is not invicible in that form. Its just like "Super Knuckles" really, but if they all have a Hyper form which they're invincible in, (they probably do) then they are totally, totally, TOTALLY invincible! And would beat anyone (including Mario and his gang, who probably aren't invincible). And Sonic rules! He can pwn anyone to hell, anyday! He is way, way, WAY better than anyone else! That's my Answer!
Super Sonic alone is invincible, as long he has rings, so one would assume Hyper Sonic (if there even is such a thing) would be as well.
Sonic. He can turn invincible and fly around.
Hyper Sonic is a form similar to Super Sonic in that it makes Sonic faster, invincible, requires fifty rings and makes Sonic glow. You must collect the rings to acheive hyper sonic.
sonic has a lot of friends. But his two closest friends are tails and knuckles.

its inposibble no one can but if some one says they know how to there lying
not necessarily. he is invincible for a period of time but if he runs out of rings he dies. I got this answer referring to the final hazard boss on Sonic Adventure 2 Battle.
All 3 would Kill Sonic Like Nothing The Three of Them Are Invincible Thor,Superman and Hulk Would Win
sonic could go super making him 1000x more powerful,has beaten omnipotents, is invincible, is faster than 1000x the speed of light, has chaos control, so sonic wins.
Yes
Because they think they are just in costumes.
Sonic can turn to dark SuperSonic because he has anger for his friends
