This story is a sequel to Metroid Equis

With the culmination of events on the BSL Research Station, Samus Aran is finally able to come back to Equestria, Planet Equis; to come back home. Much has changed in her absence, but it is still the friendly, peaceful, welcoming planet and nation that she left behind two and a half years prior. With the Space Pirate threat neutralized and the secret, illegal Metroid militarization programs destroyed, it appears that Samus can finally take another massive breather with her friends and enjoy some well-deserved rest, recovery, and relaxation. The galaxy is finally at peace.

At least... for a short while.

A new enemy, one much closer to home, soon rears its head, threatening all of Equestria and Equis with complete and utter annihilation. Their mission: revenge. Samus will fight with all of her being alongside her allies against an enemy who would like nothing more than to see all that she holds dear, including her home planet, completely razed. In so doing, her cunning, ever determined enemies unleash a weapon so unexpected, so eerily familiar yet horrifically foreign that even Samus herself just might prefer the late Ridley or the SA-X...

Canon Considerations
MLP-FiM: Up to AND including "Magical Mystery Cure." (Seasons 1, 2, and 3)
Metroid Series: Everything up to AND including Metroid Fusion (Including original mangas. See official timeline above). So, effectively everything.

Pantheon, known as the Artisan of War by the governing bodies of every city on Runeterra, has fought in more battles than anyone can remember, slaying countless enemies with his mighty relic-weapons and unparalleled skill. A mighty warrior, Pantheon lives for the thrill of battle, revering combat in all its forms.

But Pantheon has a secret.
Deep down, he has always desired to leave the battlefield behind... to be a baker.

Due to the untested magic of a rogue mage, Pantheon's secret wish just might be fulfilled, and then some.

Crossover with League of Legends. Minor knowledge of the game may be helpful, but is not required.

A Metroid Crossover

A meteor, resistant to magical manipulation, crashes in Equestria, Planet Equis, and soon spreads an unknown poison throughout the land. Containment is all but failing and the Princesses have little power to stop the spread of the Great Poison. The Elements of Harmony are of little use as no knowledge exists of this threat that consumes all life. Help comes from a certain Hunter, clad in metal.

Samus Aran will not only fight for her life as always, but her own sanity as well as these ponies that she begrudgingly starts seeing as allies. New horrors and abilities await her as a reason to fight slowly festers within her, possibly unlocking something she had been denied for so long: Friendship.

Notes and Resources:

This takes place after Echoes. The events of Corruption will have not happened yet. In terms of MLP, consider everything up to and including the Crystal Empire. Princess Twilight does not exist here, etc. The official Metroid Timeline can be found here.

As well, this story references the manga in many places. Reading of it is not required and I try my best to explain the context, but if you're interested, both volumes can be found here.

EDIT: This story was written over two and a half years, beginning in 2013. You'll probably notice the difference in writing as the chapters progress.

The sequel to League of Discord. Twilight Sparkle and her friends have successfully returned the six champions to Runeterra, but find themselves dragged along with them. They must now find a way home, despite having no help from an apathetic League, and having yet another pair of ambitious and sinister eyes watching their every move.

The year is 1109. Long under the rule of the royal sisters, Equestria is in the midst of an economic boom. New breakthroughs in magic and steam technology give rise to elaborate machinery, resulting in an exodus as adventurers scramble to chart the unknown lands outside the Equestrian Valley. Spearheading the movement are the airships Celestia and Luna, the pride and joy of Equestrian air travel.

After failing the final exam of Wonderbolt Academy, Rainbow Dash's dreams of serving aboard an airship seem crushed. But when a mysterious stranger offers assistance, she is given a second chance to make those dreams come true. Together with a calculating pilot, a stubborn engineer, an eccentric inventor, a genius record-keeper, a timid strategist and a child cartographer, Rainbow Dash will face down the unknown in a foreign land as she is thrust into an adventure beyond her imagination.

A classic tale. Twilight tries magic. Magic doesn't work. Magic ends up reaching across the dimensional boundaries of time and space to bring forth the League of Legends's most dreaded incarnation of fear on four hooves to peaceful little Ponyville. Simple stuff, really.

A delightful little story in which the Shadow of War learns that friendship is the most powerful magic of all.
... Or was it suffering? Maybe it was suffering.

The criminal organization known as akatsuki have completed their long acomplished goal of capturing the nine tailed beasts, already sealing the first seven. When attemping to seal the final two, however, something goes wrong, and the group is sent off their planet.

Waking up, they discover they have been transformed into colorful horses, yet they still posess there ninja abilities. Now travelling through the land, they begin a quest to find a way to return to their world. They are determined to get back, no matter who or what stands in their way.

This story depicts an alternate universe where the members of the akatsuki were not killed. Continuity and other factors from the origional timeline will be altered
For entertainment purposes.
