as far as i know that is
supersonic speed, Sharp, durable quills that he can cut/smash when he jumps or somersaults
some kind of wind based ranged attack (sonic wind, i'm not making it up he uses it in the multi-player mode of Sonic Adventure 2)
a boosting ability that let's him smash through stuff, he can punch/kick stuff and if he has a
CHAOS EMERALD he can use chaos control (SA2) and with all of them he can turn into Super Sonic for a while
capable of supersonic flight, she seems to be able to smash through barns and things when she's flying
and I've seen her smash into the ground with enough force to generate a mushroom cloud ( ANY sufficiently powerful impact can generate one although nuclear explosion are famous for them) beyond that i don't know any other abilities of rainbow dash, although i am pretty sure she'd be a competent fighter
My opinion is sonic would win as he has more combat experience, he fights eggman and other villains almost daily, while rainbow lives a more relaxed lifestyle... as in she's not fighting for her life every two seconds but i could be wrong. reply if you disagree/agree
I basically only like them as friends though!^^
RD: hell yeah spike rip off!!
Sonic: ''spike rip off!'' Okay then barn animal lets see how fast u r when u r dead!
RD: bring it on quill boy!
Tails and Twilight: .....
Tails: how many times did he and RD fought over who is faster?
Twilight: IT IS OVER 9000!!!!!!!!!
Tails: *slaps himself* really really
Twilight: tee hee
Rainbow: "IN YOUR DREAMS! You wouldn't keep up with me even if I broke a leg!"
Sonic: "Well, I don't think you even need to break a leg! My speed is better! You wouldn't keep up anyway!"
Rainbow: "Keep dreaming! I am the fastest thing alive!"
Sonic: "I AM!"
Rainbow: "That's it! I'm challenging you to a race!"
Sonic: "BRING IT, PAL!"
Rainbow: "IT. IS. ON!"
Tails: "Umm, Sonic? We came here for a hangout, not a race."
Twilight: "Great, here we go again. Ugh... scary... "
Tails: "Man, I'll never hear the end of it now..."
Twilight: "Geez, Rainbow! Stop thinking with your wings everytime! You might hurt someone!"
sonic:so went ot play street fighter4
Tails: Sonic and Rainbow Dash are having a arguement about who is the fastest.
Vector: Let me deal with them
Tails: sure help youre self out * in his mind: what an idiot thinks he can stop both of them having an arguement* .
Vector * take's in a deep breath and shouts in an scary loud voice *: If you two don't stop argueing right now I'm going to feed you two to the alligators !!!!!!
Sonic and Rainbow dash: were sorry and runs off
Tails and Twilight: Man that was scary as hell
Go home, you're drunk.
Rainbow Dash- Oh, is that so? Wanna race?
Sonic- YOU'RE ON!!!!!
Me: Both of you stop fighting
Anyway awesome job man
It's too much!
Sonic and RD can travel at the speed of light and all, but can they travel at the speed of dark? I don't think so >D
