Tails doesn't need Sonic for nothing! He can protect himself, he's super smart, can fly and swim and can do plenty of things better than Sonic so Tails doesn't need him to survive!! Sonic NEEDS Tails!!!

Tails always follows Sonic!!! Lol. Like his Big Brother.

Well, tell me something: if Tails can swim, why does he make rocks look like olympic swimmers, regardless, I choose this one because I was too lazy to add my own.

Sonic can hold his own, and the prove are several games. And of you've played Sonic Adventure, you'd know that Tails has single-handedly taken down one of Robotnick's contraptions: the Egg-Walker. He's also starred in his own games, such as Tails' Skypatrol and Tails' Adventure. Both can hold their own. Sonic's needto show off is what causes him to save Tails whenever he sees Tails in trouble. Now, yes, he was teased for his two Tails, but he didn't do anything because he wanted to be strong, and just cope with the bullying. He probably saw those who were bullying him as friends and that they were just playing around. WhenSonic realized what was going on, he tried to 'save' Tails, thus strting the stereotype that Tails can't hold his own.

Which I don't see how. Why would someone as adorable as Tails be the victim of bullying? I wish I could have protected him. And Sonic? He really needs to stop showing off!! Seriously!!

Tails was teased because of his two tails; he was a mutated fox. So, others made fun of him for it. Think racism or discrimination.

I Think both!

Sonic would be lost letting animals be kidnapped and letting Robotnick/Eggman take over the world without Tails.
