Name: Sentret
General Age: late child/young teen
Background: Got sucked into the Aurora Knights when her parents were killed by the Umbras. She fought to save her own life, and in the process discovered that she possessed an Aurora Crystal (when the pendant she had found in the woods was the exact same shape as the Umbra crystals, but golden). She was later discovered by Feather, who brought her officially into the Aurora Knights.
Personality: Very hyperactive. She is often annoying and sarcastic, though she wasn't before her parents died. Her personality has changed drastically with the tragic events that have taken over her life.
Strengths/Flaws: Though a very skilled battler for a Sentret, she is still a Sentret, and does not even compare in Pokemon strength to most of the other Aurora Knights. However, she is dedicated to her training, since that is all she has left. She secretly wants to be as strong as the other Aurora Knights, though she'd never admit it. Her personality should explain the rest of her weaknesses.
Other: No one really knows how, but she seems to know several TM moves... you can use this in the story however you want (or not at all; it is your fic, after all).
