Elizabeth's Pendelf

Elizabeth's Pendelf was a Pokémon Elizabeth Storybook caught in the Alola region

History
One day at the Pokémon School, Professor Kukui was teaching when Elizabeth noticed Feiring at her feet, pulling on her foot. She interpreted this as wanting to come along with her, and thus joined her. It later evolved into Pendelf.

Personality and characteristics
Pendelf is arguably Elizabeth's most serious Pokémon and can immediately tell when somebody is lying. It often uses this ability on Rotom, who lies a lot. Pendelf doesn't seem to have much room for fun and is very protective of its Trainer, one time saying "if anybody tries to hurt my Trainer, they're getting a Flash Cannon to the face."

It can also "unclasp" the cordlike appendage that wraps around a person's neck like a necklace to listen to a person or Pokémon's heart, both to know if they're healthy or if they're lying.
