It is during the reign of Princess Twilight Sparkle. Thanks to her and her friends, the land of Equestria had been relatively safe and quiet.

But when monsters from beyond the skies begin falling to the planet below, chaos quickly starts to spread.

The Cutie Mark Crusaders, (grown up by this point and working in different towns), are caught up in an attack on their disparate locations, whence they meet some heroes from the same place as many of the monsters originated.

For them and other familiar ponies, lives were about to change forever.

Crossover with the Ultraman series.

Tags will be added as necessary.

Side note: For the purpose of this story, Ponies have an ability called Innocuous Hands. They can switch between two and four legs at will.
