Fox
Sonic: And here we have a fox...named Fox
Knuckles: Yeah, that's really creative isn't it?
Sonic: Yeah! (Sarcasm)
Tails: ...
Sonic: Tails, you alright?
Tails: It's just...HE'S TOTALLY RIPPING OFF MY STYLE!
Knuckles: Whoa, calm down!
Tails: No! We're both anthropomorphic Foxes, we both have high-tech gear, we can both use space-travel, and we both have an anthropomorphic team!
Knuckles: Well sure, you may have some similarities, but he can light himself on fire, have a bit of super speed & a deflector!
Sonic: You see? You're not that similar
Tails: Yeah, I guess so.
