This story is a sequel to From the Ashes

Twilight Sparkle and the others are friends with Earth's Mightiest Heroes! How cool is that?! Following their victory, the heroes of two worlds keep in touch, visiting each other, working on projects together, and doing all the things that friends do. These are their stories.

The war between the Avengers is over. Neither side has won. The team is scattered. All Tony Stark, Steve Rogers, and the others can do now is try to adjust to this new status quo.
Until now.
Pursuit of mysterious thieves leads the Avengers to a new planet, populated by...colorful talking ponies. Oddly enough, these ponies may actually know something about conflict resolution and personal problems. The Avengers had better listen, because only together can they stop a sinister force that plans to bring both Equis and Earth to their knees.

Barney Trotter and his valet, Cheese, struggle to assist young Prince Blueblood, who has accidentally become engaged to be married. On the night of the Grand Galloping Gala, Barney unfolds a masterful plan to rescue his pal from the harness of matrimony.

A parody of PG Wodehouse's Jeeves & Wooster stories.

This story is a sequel to Stardust

Times are changing for Equestria as Twilight’s return brings with it news of people and cultures from beyond the peaceful world everypony knows. Aid and volunteers are freely offered to help the besieged humans of Earth because every Equestrian knows that’s what good friends do. Unfortunately, making friends can also have the unintended consequence of making enemies.

When the monsters besieging the humans strike at Equestria with a level of brutality not seen in over a thousand years, the cry for help is sent to all the kingdoms of the world. Honored allies step forth to fulfill ancient treaties and oaths. Enemies, old and new, bury their grievances. An alliance never before seen in Equestria will be created to combat the monsters from the void.

And because of these events, a grim but welcome sibling to the XCOM project is born.

(Coverart produced by the amazing Carnelian!)

Blythe discovers cutie marks, what they mean, and why you should steer clear of the Cutie Mark Crusaders if you value your sanity.

Sunil Nevla (Littlest Pet Shop), and Fluttershy wished they were braver. As a result, Blythe, Mrs. Twombly, and the pets from Littlest Pet Shop and Spike and the Mane 6 from My Little Pony all get sucked through a magic portal within a comic book and both groups end up in Maretropolis and become superheroes. In order to get back home, they need to stop the Mane-iac and the Biskit twins from using three silver keys that can help them rule the world.

This fanfic is actually part of my FANMADE concept of a live-action/animation reboot sitcom of Littlest Pet Shop (2012). It'd make a perfect crossover episode from my reboot.

The girls think their days are just fine at best and at worst boring.

So what's a cracking cheese-loving inventor and his more intelligent but silent canine companion to do with them?

Show off their inventions of course. What could possibly go wrong?

This story is a sequel to Equestria Ninja Girls and the Crimson Thief

When a Mutagen hoard is discovered in the town of Middlington, the Ninjas and Rainbooms head out there to recover it. All while teaming up with a girl and her entire family... of insects.

Crossover: Equestria Girls/Ninja Turtles 2012/Growing Up Creepie

(If you never saw the cartoon Growing Up Creepie I suggest you do so. You can find them all on youtube under Kabillion Channel)

Being a pony from a human world is hard. Being a Queen's officer is harder.

No need to be familiar with the crossover source material ahead of time.

Thanks to Sledge115 and Raleigh for pre-reads, and various Discord denizens for idea bouncing.

Sequel: Fusion.
