Lacy (PMD AU)

A Delta-Fairy Nihilego who accidentally appeared in the Pokémon world through an Ultra Wormhole years ago.

Scared and confused, she floated to a nearby town, unintentionally terrifying the local populace. In turn, this scared her into grabbing ahold of and injecting her neurotoxins into a nearby Charizard.

Ultimately, Lacy fled, eventually collapsing once she figured she was safe enough.

It was after that she met a young Impidimp named Adrian. The two became rather quick friends and grew up together, eventually forming Team Fae together.
