Everypony knows Twilight Sparkle as the sweet, studious unicorn whose magic powers are matched only by her incredible focus and organizational skills. When Twilight's friends make fun of the way her checklists and schedules control her life, Twilight just laughs.

One day, for reasons known only to her, Twilight goes on an unstoppable organizing rampage. Soon, Rarity decides that she's had enough, and tries to stop Twilight before she organizes Carousel Boutique into oblivion.

Twilight Sparkle is very, very organized. Twilight Sparkle has never told anypony why she's so organized. Until now.

"You can be a hero!"

Twilight Sparkle wants to be a hero. She didn't expect the most powerful hero in Equestria to lend her a hoof. She's now set on the path of legends, but it's not going to be an easy one.

An MLP x My Hero Academia Crossover.

Gore tag because If you know the source material, you know what's in store for Twilight

Twilight Sparkle is thrilled when her groundbreaking paper on friendship and magic is finally published. Surely this will revolutionize the way magic is practiced all over Equestria! But things don't always go the way one expects...

(Don't take this one too seriously.)

Once upon a time, in the magical land of Equestria...

One week ago, Twilight Sparkle was crowned the fourth Princess of Equestria. Tonight, Ponyville hosts the 1003rd Summer Sun Celebration, and Princess Celestia and Princess Luna want a vacation. With two fine young princesses like Cadance and Twilight to take over for them, nothing could possibly go wrong.

Two thousand years after the return of Princess Luna, Equestria's technology and magic has advanced far enough that the once far off dream of faster than light travel is now a reality.

And that reality is the ES Harmony, the pride of its designer, Princess Twilight Sparkle, and Equestria's first FTL capable starship. It is due to make its maiden voyage to travel further than anypony before it.

And yet when they receive a distress call from origins unknown, this ship's maiden voyage will become one the crew will never forget.

(Not a strict crossover with Star Trek, but here Equestria Girls takes place in the Star Trek Universe)

The Summer Solstice approaches and Equestria prepares for the welcome break, but in Canterlot Celestia plans in secret for the return of Nightmare Moon. Her duty is clear: take the five known Elements of Harmony and cast her own sister from the world forever. So what if her heart shatters into a million pieces? A fair price for the safety of all.

Yet as the hour approaches, Celestia’s resolve weakens as she is haunted by memories of happier times. She starts to entertain an insane, maybe treasonous, plan, but a plan that might just return her sister to her.

But no plan, however well thought out, ever survives execution and as matters spiral out of control strengths sequestered deep within others will surprise even the celestial princess herself. As you well know, this story has a happy ending but it is the journey that matters.

Many thanks to GhostOfHeraclitus and Bradel for prereading above and beyond the call of duty. Seriously it would not exist without their patience.

This story is a sequel to Changeling Space Program

Twilight Sparkle's experimental interplanetary drive has malfunctioned, stranding Starlight Glimmer, Spitfire, Cherry Berry, a changeling and a dragon on a hostile planet in another universe. With limited food supplies, very little magic, no communications with home, and no way to leave the planet, they must survive until somepony rescues them.

Fortunately they crashed right next door to another creature with the exact same problem- a creature named Mark Watney.

They're going to science the buck out of everything- and do whatever it takes to survive Mars and get everybody home.
