This isn’t shipping, according to the author’s own description on DA.

Ah.

@SuperSupermario24  
Yes, now. When I commented that, the image was “new”, and not a duplicated. In that moment there wasn’t any upvote, just -17 of score.

It’s the hazard crossovers. A lot of people dislike crossovers from the get-go, but by all accounts, the Sonic the Hedgehog fandom is one of the most toxic, repeatedly crossing between ‘so bad it’s funny’ and ‘just no’, sometimes cringe-worthy fandoms out there. While people from other fandoms like to shoot off at the mouth about Bronies and how they can’t leave things without ponies in them the way they are, the Sonic fandom always has, and always will continue to have done it longer. Prolonged exposure to the internet, particularly if you are not a fan of Sonic the Hedgehog, often leads to the ingrained “Ew, Sonic” response, much like ponies often get.
 
I can appreciate Sonic the Hedgehog because I grew up playing it on the Sega Game Gear, and later the PC, but even I have a tendency to prefer the two remain separate due to the sheer amount of narm ultimately resulting from the two meeting.
 
That said, I like the effort and quality in this, even if it looks a bit sketchy.

man this pic is old

cute picture  
still gets downvoted. k

I usually don’t like the crossover of these two characters, but I have to admit that this is very good. So bad that only receives negatives points, without even caring that is very well drawn. A shame.

Oh I remember this picture, I like it, don’t see a problem with it.

Don’t care on anyone else’s opinions and neither should anyone else because they’re just that, opinions. But my opinion on this image, it’s pretty adorable. And also, agree with SuperSupermario24 on this because it’s kinda disappointing that I found images with downvotes beyond even 100 that had a lot of effort put into them. That kind of thing is actually what made me stop making pony art in general, though I am a bit oversensitive. So I’m just going to leave one of my quotes here:  
“If you don’t like it, walk away.”

It is kind of disappointing how actual good-looking art in general gets so bashed just because it has Sonic in it.  
I mean, there is the stuff that deserves it, but it doesn’t deserve to be flooded with downvotes just because it has Sonic in it, even if it’s shipping.

@SuperSupermario24
 
it’s called “acknowledgement of actual originality and artistic effort…” a rare thing in the sonic fan art.

waaat  
a sonicdash that’s not being flooded with downvotes  
WHAT IS THIS SORCERY

Well, I think its only fair that sonic give her a pair of those shoes

@G.S.  
Is that from a real FanFic?

“Hey, I’ve been wanting to ask; where’s your cutie mark?” Rainbow Dash asked, her voice cracking with curiosity as she poked his waist. “Is it somewhere else?”
 
Sonic blinked in confusion, looking over his shoulder. “A cutie what?”
 
The little pegasus flapped her wings and circled him, searching for the aforementioned graphic. “Oh… do you just not have one? Are you a blank-flank?”
 
Sonic could only blink again, twisting his body to keep track of the pony. “What?”
 
“You look like an adult.” Rainbow Dash frowned, landing on the ground with four soft clops. “Wow… it must be tough. Uh, here.” She produced a paintbrush from her mane, holding it it in her teeth with a small grin. “Maybe this’ll help you feel better.”

@Starly  
Wat

@Background Pony  
Sonic: Sorry Dashie, but this Big Blue hedgehog is already owned by Sega. You don’t own me. You only painted your cutie mark on my rear.
 
RD: …That means I own you.
 
Sonic: You didn’t write “property of Rainbow Dash” down there.
 
RD: God damn it… you win this time Sonic.
 
Sonic: Hey don’t get upset now, Dashie. I think you should know that we both have free will, but you shouldn’t try and claim living creatures or beings like me as yours. If I painted a picture of my shoe or a ring on your face or neck, Would I want to own you?
 
RD: Maybe… why do you ask?
 
Sonic: because I don’t want to own you, I just want us to be close friends. Does that sound good with you?
 
RD: hugs sonic Yes! ^ _ ^

@MonkeyDzyrax  
It’s more ‘cute’ than shipping in my eyes.
 
@Background Pony  
Out.

A sonicdash picture that is being uploaded?  
what is my life?

the two greatest autist magnets in history

Either RD is the world’s most skilled painted, or Sonic is insanely oblivious.

This is a throw back, I think this is the first brony fan art I saw back in 2011.
