Alicorn

“	You are not the prize we are looking for. But it will be a joy killing you anyways,	”
– Two Alicorns finishing one another's sentence

Alicorns are a race of pony that possess all three distinguishing features of the other pony races: the horn of a unicorn, the wings of a pegasus, and the fortitude of an earth pony. As such, this also grants them access to the inherent magical abilities of all three races: a unicorn's ability to directly control magic, a pegasus' ability to fly and manipulate weather, and an earth pony's natural affinity to the earth. Prior to the war, alicorns were considered goddesses, and the only two known alicorns were Princess Celestia and Princess Luna. Alicorns often travel in groups of three called "wings".

History

After the death of Princess Celestia and Princess Luna, the only alicorns in Equestria are artificial, created through deep exposure to the I.M.P. fluid developed at the Maripony, Ministry of Arcane Sciences facility. They have only been a visible presence in the Equestrian Wasteland for roughly ten years leading up to the opening of Stable 2.

Modern Day

Alicorns are one of the most feared sights in the wastelands, due to their abilities, malevolence and loyalty to The Goddess and Red Eye. Littlepip and her group has came into conflict many times with alicorns and are often only able to win through a mix of luck, surprise or overwhelming firepower.

The Alicorns having lost the leadership of the Goddess along with Maripony were left with no means to survive as a species, turning to seek out Red Eye, who planned to become an Alicorn himself, and promised to create Male Alicorns so the Female Alicorns the Goddess made would be able to procreate and survive. With the death of Red Eye, along with the re-created I.M.P. Facility built beneath The Cathedral, the Alicorns decided to turn towards Velvet Remedy for help since her kindness helped save their lives at times, dubbing the unicorn as their de-facto leader. They remember Velvet showing them compassion and Littlepip as one who kills them but want no further confrontations with Littlepip who they now deem The Destroyer. The Alicorns assist Velvet Remedy in her part of Littlepip's plan protecting her from the Enclave Pegasi in order to gain control of the Single Pegasus Project and completely end OperatioN Cauterize once and for all.

Also worth noting is the Alicorns abilities appear to be growing now they are free of the The Unity as shown by the Alicorns using each other's abilities regardless of color.

During the Epilogue, set a decade after the events of the story, the zebras of Glyphmark managed to successfully synthesize a compound that would be able to turn Alicorns male (a brew which Fluttershy noted included Killing Joke extract), allowing the Alicorns to naturally procreate. In the New Canterlot Republic which was set up by Velvet Remedy and Calamity, a pink Alicorn filly named Surprise lives in the small town: the third such Alicorn to be naturally born, but also the first whose coat color wasn't a form of Purple, Green or Blue like the artificial Alicorns.

Appearance and Abilities

The synthetic alicorns (or alicorn drones) are all female (even though both male and female ponies can be turned), with no cutie mark. Alicorns are dark-coated, although they vary in appearance and specialty, with the three varieties each corresponding to the unicorn mares "who were powerful enough to exert influence over the alicorn creation process."

Alicorns with dark purple coats have the ability to teleport, as this was Twilight Sparkle's special ability. Dark blue alicorns can turn invisible, as Trixie was the only unicorn to develop such a spell. The dark green alicorns can generate nearly impenetrable shields, and can cooperate with other green alicorns to amplify their powers. They also have greater telepathic abilities, which can be used cooperatively to overwhelm a single subject's thoughts in a form of limited mind control. Their power comes from the green pallet-swapped twins Gestalt and Mosaic, who had the odd habit of not only finishing each other's sentences, but even each other's spells.

Alicorns are telepathically under control of The Goddess, and anything witnessed or experienced by one alicorn is learned by all of them simultaneously. As Littlepip quickly realizes, the same trick doesn't work twice on alicorns (unless they severely underestimate an opponent).

In addition to their inherent color-specific spells, alicorns are also able to borrow spells from the minds of the unicorns that make up their Unity hivemind.

Alicorns are immune to the effects of radiation and taint, and actually even benefit from exposure to it. They can bask in radiation to regenerate wounds and lost limbs. They are also able to supercharge their powers through exposure to areas with high levels radiation, such as the Fillydelphia Crater, growing in both size and capability. Conversely, proximity to Pink Cloud has a disruptive effect on the telepathic abilities of alicorns, forcing them to awkwardly revert to speaking aloud. Owing to their similar appearance and malevolent tendencies, zebras refer to alicorns as Nightmare Moons.

Hellhounds and heavily armed Steel Rangers are the only things that can reliably defeat alicorns.

Notable Alicorns

Princess Celestia -Ruler of Equestria and eventual co-ruler of Equestria. Abdicated the throne to Luna.

Princess Luna - Formerly Nightmare Moon. Ruler of Equestria during the Great War.

Nightmare Moon - A transformed Princess Luna.

Nightseer - An artifical alicorn leading the others in Canterlot. She wore Princess Luna's skull as part of a necklace. Killed by Littlepip, who telekinetically killed her using the skull's horn to stab her in the head.

Surprise - A pink Alicorn filly of natural birth, she is a citizen of the New Canterlot Republic and is noted by Fluttershy during the Epilogue as the third to be born; yet at the same time the first whose natural coat isn't a shade of purple, green, or blue.

Appearances of Alicorn in Fallout: Equestria Side Stories

Warning! The following information applies only to its associated side story, Fallout: Equestria Side Stories, and is thus considered non-canon in the Fallout: Equestria universe. Loyalty After successful testing of the M.T.S (Magical transformation serum), the first artificial alicorns were born with the help of volunteers. These would be labeled the 1st generation Alicorns (or FGAs for short). These alicorns would be extremely tough in battle making them hard to kill, breaking the stalemate of the war in Equestrian favor. The demand for alicorns increased in order to ensure victory but the current serum was too slow of a process as it took a 5 weeks for a pony to become a full alicorn. A much faster but unstable version of the M.T.S labeled M.T.S2 would see a 2nd generation alicorn in just 1 week, however it was not without side effects. Males would suffer permanent infertility and in rare cases depression. A more physical side effect would be a long drooped mane and tail compared to a female alicorns hair which flowed in waves. Female alicorns of the 2nd generation would suffer from mild acts of random aggressive behavior, their hair still flows but at a much slower level. Note: Natural alicorns have immense magical powers and as such in order to become one, a ponies natural life-force must be changed to match the immense power of an alicorn. As a consequence you lose your cutie-mark, however your talent remains.
