My Little Pony: Friendship is Magic its Equestria Girls franchise are a great TV and movie series for kids. But what if some very dark secrets lurk within Equestria? Is Equestria really only the post-apocalyptic future of Equestria Girls? Is King Sombra truly still alive? Is Lyra possibly a secret villain?
Post-apocalyptic future of Equestria Girls
This theory suggests that Equestria is really the post-apocalyptic future of Equestria Girls. Let's look at the evidence. During Lyra's song, she asks "Who's to say they're all gone?". To prove Equestria is a post-apocalyptic future, there needs to be old junk used by humans, ruins, and the powerful beings must know about this. For the unused items, there are saddles (for some reason), horse drawn carriages, mugs, printing press, cameras, other cups, and that one car tire in the dirt in one episode.
Nothing seems designed correctly for the autonomous use of ponies. So that's one thing for a post apocalyptic Equestria crossed off our list. Lots of ruins? Check. Well, not really. The only real major ruin is the Castle of the Two Sisters. Which, as we can see, was fine a thousand years ago, and there's really no telling how old Celestia really is. But that doesn't explain why she says Twilight will soon know more about the human world than even she does. Was she lying?
King Sombra is still alive
In The Crystal Empire Part 2, Spike returns the Crystal Heart so that it can save the citizens and the city from the shadows of King Sombra. King Sombra's entire body is affected by it's light and it shatters to pieces. Some fans theorized that he may still be living. He had not made any returns(not including his appearance in The Cutie Remark Part 1), until in The Beginning of the End Part 1, Grogar(who was Discord in disguise) casts a spell to resurrect King Sombra. He along with Queen Chrysalis, Lord Tirek, and Cozy Glow were told by Grogar to destroy the Mane 6's alliance by working together, but King Sombra refuses to listen and starts an apocalypse by mind controlling all whom the Mane 6 loved and cared about. Luckily the Mane 6 use the Elements of Harmony, but Sombra manages to escape and later destroys the elements and their Tree of Harmony. When all seems lost, the Mane 6 realize that their friendship was more stronger than their elements. With friendship the heroes successfully destroy King Sombra once again.
Sunset Shimmer is her own clone
In the worlds of Equestria and the human world of Equestria Girls, there are two clones that live in different worlds. When Princess Twilight Sparkle enters the human world, she meets the human counterparts of the Mane Six, including a human Twilight. Sunset Shimmer's human clone has never been seen or mentioned so she is perhaps the first pony from Equestria that may lack a clone. Otherwise her human clone, may no longer exist. In the human world, there are many inhabitants whose pony clones are never seen or mentioned throughout both franchises(not including their appearance in toy boxes or fan art).
