Oh yeah, this is the point where I now do the thing deciding if the events of Season 5 (Starlight and the time travelling) and the S6 Premiere (small crystal princess horse) are canon to the PC-verse.

Maybe and yes respectively.

I was thinking of continuing the gag of “Twilight viciously wrecking every power-equivalent villain she faces.” 

First was Sunset Shimmer, who upon her gaining the crown at the end of EqG, engaged in battle with Twilight and co., laid waste to most of the school, and then ended up in a hole she never climbed out of. Twi returned to her world with extra anxiety and promptly banned portals so that never happens again. I’ll admit, this was because I was rather against EqG when it first came out and I don’t hold the same opinion anymore but I can’t change the past or future or whatever.

Second was Starlight. However, no specifics were ever drawn up and TBH I kinda like Starlight and don’t want her to be absent in PC (concept-wise :v). But hey, who knows. Time travelling is quite canon, though.

As for Flurry Heart, yes she’s canon. No questioning it. Hell, I was gonna canonize Skyla anyways but now there’s an actual baby in the show so yeah, less work for me o 2o.
