From Bulbapedia, the community-driven Pokémon encyclopedia.
Pie was a mod from the Bulbagarden forums. Nowadays she pretends she doesn't like this fandom anymore and wants nothing to do with it like a huge tsundere. Silly Pie, no one just ups and leaves the Pokémon fandom. You'll be back. They always come back.
She used to have an unhealthy obsession with Brock, but that has reduced to FDA-approved levels ever since she started dating a real, live actual guy. She also thinks Cilan is pretty cool, despite replacing the best character on the anime, since he's a classy foodie dork and how could anyone not love that. Like Alton Brown but with a monkey, you know?
Her favorite Pokémon is Sandslash, but in truth, a Stunfisk suits her better.
