It's the My Little Pony ship of Pinkie Pie and an alternative version of herself! Let me show you 6 examples of this cause it happens a lot lmao
This mirrorship is from an episode where Pinkie clones herself so she never loses any type of event involving her friends, it's a really sad episode, but her clones are really fun. Most of the clones died, but some ran away and live their life in hiding. Some people ship Og Pinkie with her clones!
Changelings are creatures that can take the form of anypony to feed off their love. It's not exactly mirrorship, but it's still someone that can look exactly like her, and has done it many times!
Pinkie x Equestria Girls Pinkie
It's a canon alternative universe where the ponies are human, the portal is a mirror (lmao), if you are a pony and walk through it, you turn human and vice versa. They canonically change places with one another!
I don't really like this one tbh, because pony Pinkie is a full grown adult while human Pinkie is a high schooler, this was a marketing tactic to sell the series to children but it's a decision that I really hate, it's weird seeing 20+ chars with jobs as stupid children
Pinkie x Alter Ego (Pinkamena)
When Pinkie gets extremely sad (a rare occurrence) she transforms into a full alter ego who's a bit manic. Ever since the start of fandom days people have been drawing these two together like they are a system, enemies, etc etc. Recently there have been some edits and ship art of them!!
Recently on Twitter, someone said it would be cute to ship MLP characters with their previous generations, this is the older version of Pinkie before the reboot. I think they'd be cute together
Pacific Glow is a character that appeared in one of the episodes, she caught everyone's attention for looking exactly like Pinkie. Some people believe she's a runaway clone or an alternative version. She has no official name as far as I'm aware, but everyone collectively decided to call her this. Among the Pinkie ships, this is a really popular one, and one of my favorites!
