The Transformers crossover can’t be canon because it makes the Ponies OP.
 
It invalidates pretty much everything else. How would the Storm King have conquered Canterlot if they were the same ponies capable of kicking Decepticon ass?

Crossovers are rarely canon to any and all series involved.

What about the Transformers crossover?

@MezzoDragon  
But the comics are canon. But Siege of the Crystal Empire, some of the flashback scenes in Relections, and Siren’s origins from FIENDship is Magic are not.

@Background Pony #46E9  
Well it would be canon to the franchise. Siege of the Crystal Empire is not canon to the tv show. And image a proper plot of the Sirens/Dazzlings origins which happens before they meet Stygian. The makers of the show don’t want us to see King Sombra reformed because they made a better plot of King Sombra’s resurrection in the season 9 premiere.

@Background Pony #46E9  
As far as I can tell, the comics are canon unless contradicted by the show proper. Since the show is now over, it is hard to say if the comics will truly be canon or not.

Is IDW considered canon? I feel like there is a contradiction. In the comics, Sombra was redeemed, while in Season 9 of the show, he was defeated.

Who says they weren’t sent to the future? Its not like they went through the mirror. Who knows how the spell works?

I don’t get it! Modern city already built during the ancient times?!

@Red Yellow Moon  
What? No! Star Swirl didn’t send the Dazzlings 1,000 years into the future and banished them to the human world at the same time. The epilogue shows us something that is so strange because why are the modern buildings are built early 1,000 years before the present time? The Dazzlings are immortals because they have been banished in the human world for 1,000 years.

Why is this city modern instead of ancient. I mean this comic is not canon because they got a little carried away by showing Star Swirl the Bearded banished the Sirens/Dazzlings to the human world with the Crystal Mirror instead of making a portal in sky which is shown in both Rainbow Rocks, Shadow Play part 2, and Legends of Magic Issue #12 So I think the epilogue of FIENDship is Magic Issue #3 was canon. So in my opinion instead of banishing them to the human world if this issue is canon, then maybe Star Swirl would banished the Sirens out of Canterlot while the Sirens continued to invade and hypnotized Equestria until it was shown in Issue #7 of Legends of Magic. So in the epilogue, Star Swirl didn’t sent the Sirens to the future and to the human world at the same time because something’s not right. So after reading Legends of Magic Issue #12, you must read the epilogue of FIENDship is Magic Issue #3 before you read the present day epilogue of Legends of Magic Issue #12. Because that would make it canon.

I liked the idea of them being immortals better.

@Red Yellow Moon
 
Well i can guess that when the portal is closed time moves faster in equestria that it does in the human world. When its open its reversed. Examples:
 
-Sunset whent trhough the mirror when her ages was the same as current twilight, in that point Twilight was a filly but when sunset returned she didnt seemed to age at all.
 
-When Twilight return from the Human world it seemed that in Equestria time didnt moved as it almost seemed she returned almost instantly instead of the 3 days she spent in the human world. I say this because her friends never seemed to move from the chamber(Exept Luna and Celestia).
 
For the sirens i can say for them it has been 1-3 years from their banishment but in equestria it has been 1000 years

A world without magic. Not since the show ’’Once Upon a Time’’ have I heard that term.

@RedTriangle  
Yep.

@MezzoDragon  
Right…. I get the joke. Lol

@RedTriangle  
Basically, time and space is Discord.

@Jediking69  
So your saying time and space is not constant but random and chaotic?

@RedTriangle  
Yep.

I don’t get it, I mean I have some ideas of what’s going on but is that possible?

@Animegx43  
It’s okay. But I prefer Sonata’s plot.

@Red Yellow Moon  
For the plot’s sake.
 
Gotta love Adagio’s plot.

Why did the mirror send them 1,000 years into the future? That mirror looks like the one Twilight used, so why didn’t it do the same thing (send her several years into the future) to her?
 
Also, why did Star Swirl send the Dazzlings 1,000 years into the future? Was that ever explained?

@Background Pony #7F3A  
or better yet, they go to japan and become a BIG hit in the j-pop biz.

@Background Pony #7944  
Implying the Dazzlings founding the KKK isn’t god-tier
