Me and my friend decided to take a page from PSO2. I was wondering who should we give a Phantasy touch to the two remaining members of the mane six that has yet to be anthrofied. We both went on Fluttershy and decided to make her cosplay/become one of the iconic characters of PSO2's story mode. The character in question is Dark Falz: Persona. To avoid story spoilers to those who haven't played PSO2 or got that far into the story, I'll just simplify Persona. Dark Falz Persona is an event miniboss out to kill the player character who can, more or less, use the same Sword or Double Saber skills as the player.

As for how Fluttershy became a Dark Falz, Stephan suggested that it was caused by a time anomaly. She encountered something radiating with a high D-cell count that began to symbiotically fuse into her.

Pershyna was made in 3DCG with the help of my friend Stephan & KP-Shadow Squirrel
Coat Edge D (the sword) was made by Claisen and is owned by SEGA
