My theory how G5 Happened · 4:07pm Aug 15th, 2021
Here's my theory how G4 became G5. An evil, Dark Lord of the Dietitians came towards Princess Celestia and put her, and all alicorns on a diet. They gave up cake, and other fattening foods. The ponies became no longer unified by the worship of big fat alicorn booties since the alicorns lost so much weight. Since cutie marks are on asses, they no longer worked and magic failed. Ponies need to inhale lots of cake and fattening food into them to power up their bodies. Civil War broke out, and everyone blamed the unicorns and alicorns for promoting healthy eating. The evil Dietitian then hid underground and smiled as his work was done.
The Dietitian may in fact be Sauron, from the Second Age, pretending to be a pony by shapeshifting into one. But he's too busy in Middle Earth to conquer Equestria.
This theory holds.
All hail the bubble booty and the thicc thighs.

The dark times have come. The ponies began eating low-fat food, and brought about an age of darkness.

Indeed. It seems possible.
I hate the fact that by following the logic of how the fans usually write the princesses, this makes at least 90% complete sense.

Indeed. My theory has legs.
Those bastards!

Doesn't even really need to be a time-traveler in the traditional sense, could just be Spike taking the long way to the future.
