EVERYTHING’S CANON!!!

@Background Pony #CDF2  
Well, I didn’t dig that far back in the comment thread, my bad.

@Animanga21  
And that post was about the comics, not Equestria Girls. EqG is explicitly in the same continuity as the show.

@Animanga21  
We already have episode synopsis saying it does.

@Background Pony #CDF2  
Depends on whether the season 5 finale involves time travel in some variety. If it does, then the movie is canon, and was just released too early.

the portal

Those openings are clearly different than the constructed portal.

Just imagine, what would happen if Midnight Sparkle go through the portal and she still would be in human form.

@Background Pony #788B  
If you look closely at the portals, you can see that some ponies are looking directly at the portals, with new knowledge that there are strange creatures on the other side of the mysterious portals.

Actually, it was only Spitfire they rejected for not being mean enough. Lightning Dust was a candidate to be part of the Shadowbolts and it shows in the prototype for the dolls. The writers just decided that they would rather have original characters instead and went with Indigo Zap.
 
@Background Pony #93AC  
Yeah, this was from the audio commentary. Originally, when Cinch walked off, she was supposed to fall into something. That something was either a crater which would have been from the Daydream/Midnight battle (Originally, Sunset and Twilight were supposed to be in there post-fight as a nod to fight in the previous movie) or a stray portal which would have Cinch show up in Equestria as an ugly creature. Both were obviously scrapped (The former due to removing the crater and the latter due to being too mean).

Seems easy to think that the mirror is a magical device and the portals are just rips in space/time. Thus the mirror has no means of, for the lack of a better term, “translate” a being traveling between universes through a rip somewhere else.

@Background Pony #788B  

 
Okay. How in the world did you get you get internet access, Lyra?

@Background Pony #93AC  
If I’m not wrong, Friendship Games DVD’s audio commentary of the scenes that were cut. They also mentioned that before Indigo Zap, Lightning Dust and Spitfire were considered to be Rainbow’s Shadowbolt counterpart but they weren’t mean enough!

While watching this scene of Midnight Sparkle opening the portals to Equestria,I’m wondering over like………
 
DO ANY OF THE PONIES SEE THIS SH1T!!!!!!!!!!!!!!
 
THIS IS PROBABLY THE ONCE IN A LIFETIME OPPORTUNITY FOR THE PONIES TO SEE THE HUMANS AND I’M OVER HERE EXCITED SO BADLY,THAT I’M GONNA EITHER PASS OUT OR DIE!!!!!!!

@Background Pony #5353  
Never heard of this. Source?

Judging by a scene that was cut before storyboarding stage (where Cinch would fall inside one of these portals as a hideous creature while trying to escape), I just think they weren’t inside enough.

@John23  
Depends on how your using ‘canon’. If you mean ‘part of the overall franchise’, then yeah, it is. If you mean ‘set in the same continuity’, then it clearly isn’t, there’s too much contradiction.

@dynamicv  
Ah, I see. Tho I can’t really be sure what a review by Hasbro execs really means… I mean, the execs probably aren’t the creative driving force of the series. How much time would they really spend sitting down and hammering out the particularities of canon? A review by them might just amount to some checks to make sure this story won’t break laws/harm the brand/make the series hard to sell across the globe/etc. After all, I assume the toys they sell also get some sort of executive review, and I know some of those can get pretty odd (like AJ often not being paired with her Stetson, or that funny Apple cart car thingie that they sold a while ago).

@Background Pony #CDF2  
Everyone ignore this guy. He is just deluded, thinking that the extended universe is not canon when several times it has been confirmed it is canon.

@dynamicv  
But that’s just reviewing for the brand as a whole. Just because they say “We approve this story idea” isn’t the same thing as saying “This story happened in the same continuity as the cartoon”. It’s like trying to say the Michael Bay TMNT and the Nickelodeon TMNT are the same continuity. They’re based on the same source material, but they’re different versions of each other. The IDW comics are the same. It’s based on the same material, but is it’s own alternate interpretation.

@Exedrus
 
The fact that the same Hasbro executives review every script and storyboard of the show as well as every script and page of the comics, and send the creators notes when something doesn’t fit their vision of the canon.

@Exedrus
 
That’s legit questions actually… In case of Star Wars extended universe, for example, creators lately seriously reconsidered what is canon and what is not… Nothing stops Hasbro from doing such a thing in the future too…

The best way to regard the comics is how the new Star Wars canon is. Star Wars now has two continuities. The movies/CGI shows/disney-era books & comics (The MLP Cartoon) and ’Star Wars Legends, which is all the EU material produced before the Disney buyout (the IDW comics).

Don’t forget the EqG comics are both completely incompatible with the films.  
The first one shows Sunset the same age as Minuette/Lemonhearts/Moondancer/Twinkleshine, but older than Twilight, while the show has Twilight growing up with them.  
The comics show Moondancer with a completely different design  
The comics show Sunset in communication with Twilight & not knowing what a slumber party is in the same story, despite her going to one in the second movie, and not beginning her communication with Twilight until that same movie.  
The comics show Sunset living at the school, which contradicts the first movie (if she lived there in the first movie, she’d have seen/heard Twilight, since she was speaking to Spike in an empty library.) the second movie (If she lived there then, she’d have likely said something when the others wouldn’t let Twilight sleep there) and the third movie, which shows her running to the school in the morning after Rainbow contacted her (if she lived at the school, she’d have already been there), as well as the Sunset Shimmer chapter book, which refers to her going to and from school (it may not be the same level of canon as the movies, but it’s certainly closer to canon than the comics)

@Vaidelot  
Hmmmmm, not sure what “Extended Universe” canon really means. Like, to me if something is canonical to the show that means that any writer for the show is expected to have read/understood that information before they are allowed to write anything for the show. (And that they won’t try to contradict it.) So the value of being canonical is that we can rely on that information not being willingly/knowingly contradicted at some point in the future, and that this information is all we need for the writers’ writings to make sense.
 
I guess I just don’t see the value in saying that there is an Extended Universe canon, if all that means is the canon of that universe can be overridden at any time. I mean, if we can’t rely on this extended canon to actually remain canonical (or to be necessary for things to make sense), then what really separates it from any fanfiction’s canon except that its source pays Hasbro for access to the trademarks/copyrights?
