In my opinion Spike’s cutie mark portray’s him more as a scribe.

Judging by his cutie mark, his destiny is to be an assistant.
 
…Not that he probably cares much about that at the moment.

This pony Spike looks familiar with some rascal purple Pegasus oc…

Ok then, I dun derped.

@Spiked Punch  
Easy, Punch, we’ve settled that it’s just our personal beliefs and they don’t effect one another. Let us all to our beliefs.

Wait…so we’re “deciding” he won’t grow wings because both times he grew (unnaturally) he didn’t have wings…even though both were also completely different from one another?
 
So… if both forms were completely different from one another…then how exactly are we “deciding” that one of them is his “canon” adult form? And which then? By which standard? And what about the other one? Neither of them can be assumed more valid that the other, which means neither can be assumed as canon, which means moot.
 
For the record, Im not saying I definetly think he will grow wings (he might be wingless), but I don’t get the logic behind the statement that he definetly WON’T. It makes no sense since he grew by magic and by greed and both forms couldn’t be more different.
 
Both times he grew, he looked completely different, which gives each respective form as much validity as whatever form he might end up growing up next (if he does). We can’t assume a form is canon until it is stated in the show to be his TRUE, adult form.

@dragonSpike  
We’ve seen that non-standard body types exist, but are rare. Dragon Quest did have a non-copied adult dragon, after all. Therefore, Spike just has a rare body type.
 
The idea that the dragons will all end up with the same body type requires Crackle to have limbs fall off. That seems pretty unlikely to me.
 
Think of it as how most ponies are cookie cutter copies but some have unique bodies. As dragons were shown to have a greater array of features… Heck, some places consist almost solely of one pony type. The migration may have been more like Cloudsdale than Ponyville when it comes to population demographics. Non-winged dragons might just not migrate most of time.
 
Not that we saw the whole migration. It’s possible that wingless dragons simply hadn’t arrived yet.
 
Not impossible that Spike could grow wings… But no reason to think that it’s likely, and more than a little reason to think that it won’t happen. Not from natural growth, anyway.

@Sjogre  
I’ll admit: When it comes to teenage dragons, yes, they have all sorts of body types.
 
Not when it comes to adult dragons, though, again, with the exception of Greed!Spike. Yeah, it’s possible that we just haven’t been shown the others but they do exist, it’s not official that there CAN’T be other types, but I, personally, will not believe it’s impossible for a being based around magic (Can be burned but not by lava?) to start sprouting extra limbs.

I also prefer his ponified form as unicorn. Always considered him as a magical dragon instead of a typical fire breathing winged creature.
 
Nothing in show says he will/won’t sprout wings, though. All dragons seen so far comes in various shapes and sizes. The one with the giant tail with retractable spikes had no wings either.

@TenchiFreak5  
Or, you know, those other dragons hadn’t reached the age Spike was at when he got that growth spurt. Or they hadn’t had the chance to grab a bunch of stuff like he did. Or Spike had an unusually intense growth spurt as the result of usually suppressing his own nature.
 
It was pretty much said to be natural in the episode. The episode with the other immature dragons didn’t so much contradict it as avoid the subject entirely, not giving us any information on it at all. For all we know, those dragons were hatched in that migration.
 
Given how little is known about dragons, it’s early to call Spike’s growth contradictory, as there are ways to reconcile it. On the other limb, the show has been extremely consistent about him not getting wings, and has shown that dragons have more than one body type, so Spike not having wings as an adult contradicts nothing, anywhere. Getting wings contradicts information that we’ve already seen without agreeing with anything.

@Sjogre
 
And, again, none of the other episodes fall in line with that; so I don’t see any reason to think that dragons growing up as time goes by (rather than the “steal shit, get progressively stupider while growing larger” present in pretty much only that episode) is irreconcilable with canon.

@TenchiFreak5  
I’m talking about the time we saw him grow up due to his own biology. Secret of My Excess had no outside influence or magic. That was all due to his own nature.

@Sjogre
 
The time we saw him grow up when Twilight force grew him with (literally) completely random magic, or the time we saw him grow up due to completely different magic which didn’t seem to be particularly in line with the other episodes about dragons anyway?
 
 
You’re saying the headcanon was contradicted. I’m asking what contradicted it that holds up to scrutiny well enough to claim it can be used as a foundation for such an argument, because nothing I’ve seen in the show does so.

@TenchiFreak5  
That time we saw him grow up? And that picture on the side of his egg’s cart strongly implied that the ponies knew what one of his parents looked like, or that wingless adults are common enough that the ponies decided to put a picture of one of them on the side.
 
@Background Pony  
Technically, we didn’t see his back the first time, and that was actually a magical transformation rather than pure dragon growth mechanisms.
 
Given that Twilight’s parents were turned into plants, that transformation has less weight than other things we’ve seen. Especially since we never got a full body shot.
 
@Itsthinking  
You do realize that nothing in the show has ever implied Spike’s growth spurt in Secret to be unnatural, right?
 
It might have been oddly fast, but that’s about it.
 
More importantly, we’ve no reason to think that growing up slowly would result in a different form than the one we saw, even if it was unnatural.
 
Zecora’s segment basically had her saying that what he was going through was normal.
 
Spike getting wings requires him to grow two limbs, complete with bones, ligaments, and nerves, out of nothing. Even his ears are already around in a simplified form, and ears are far less complicated than full limbs.

@Itsthinking  
But why would he sprout wings ‘cause he grew differently? Wouldn’t it makes more sense for him to get wings if he grew up with greed to make stealing easier?
 
My point still stands. There’s no evidence but headcanon to suspect he gets wings and there’s plenty of evidence to subject that Spike is a wingless dragon. Why would he just grow wings?

@Background Pony  
We’ve seen him have forced growth as a newborn and forced growth as a result of greed.
 
We haven’t seen him grow naturally. And honestly, it could be a decently interesting story.

@dragonSpike  
…(smacks forehead) We’ve seen him as an adult! Twice! He doesn’t get wings!!
 
 
@Sjogre  
What this guy said! Yeesh.

@Sjogre
 
When was it contradicted by the show?

Guys, excluding Spike, ALL of the adult dragons and half of the teenaged dragons had wings. Spike was never fully an adult, though, he was simply grown. There’s still the potential that wings come with age!

@Itsthinking
 
He also gets a lot of criticism for the way he axes off characters like Lane Thunder and Fancy Hats.

@M  
“Charity had always had her eyes on Lance, and now that he had transformed from a griffin into a pony, she could no longer contain herself.”
 
Spike rewrote Lance to be a griffin instead of a dragon because he felt like it was too obvious.

@Lium  
We’ve seen another dragon without wings. We’ve seen Spike as an adult without wings. We’ve seen that the picture of an adult dragon on the side of the cart with his egg didn’t have wings.
 
Finally, we’ve seen that dragons have an extremely wide degree of morphism, up to and including variable numbers of limbs.
 
Logically, he’s just a wingless dragon.

@Background Pony  
I derped, but my point still stands.

I just assumed @Lium  
We’ve seen him as an adult. He doesn’t have wings.

I see Pony!Spike to be more of a Unicorn,imo.
