Delta Guardian

Delta Guardian is a My Little Pony: Friendship Is Magic fan fiction written by The Emerald Nightingale of Fimfiction.net.

Plot
Having been sent to Equestria from her not-exactly-consensual home of "The Asylum", Zinnia Kazoku now has to defend her new home from the evil forces of Darkrai as the Shadow spreads the Nightmare across Equus.

Main Characters
Zinnia (Zoey) Kazoku Having been plucked straight out of a mental asylum, Zoey adapted quickly to her new world, originally believing it to merely be a medication-induced hallucination. She even slipped into her new name - Zinnia - without thought. Following a sudden and victorious battle against a wild Hydreigon in the Canterlot Castle Statue Gardens, Zinnia was gifted with the egg of a Salamence to raise as her own, the egg's true mother awakening the power within her as a Draconid to protect the child. Zinnia is still discovering her powers. Slowly but surely, however, she is gaining strength, ready to end the evil that is plaguing her new home.

Darkrai One of the many sons of the Pokemon God Arceus, Darkrai seeks to use his dark powers over Nightmares themselves to plunge the world of Equus into an eternal darkness, where he will reign supreme. Spreading the Nightmare Parasite across Equestria to Ponies and Pokémon alike, Darkrai is amassing a Dark Army, prepared to send them to their bitter ends in the pursuit of his goals.
