Ah, the mime family.

Mime Jr.
The Mime Pokémon
Type: Psychic/Fairy
Official Registration #: 439
Entry: As a defensive maneuver, mime jr. mimics the expressions and motions of its predators. The enemy pokémon is thus so taken aback by this display that it can’t help but to hesitate long enough for the mime jr. to get away. The effectiveness of this maneuver may be difficult for some people to understand, so for a better idea of how and why this works, one should spend any amount of time in the general vicinity of a person and their younger siblings.

Mr. Mime
The Barrier Pokémon
Type: Psychic/Fairy
Official Registration #: 122
Entry: The evolved form of mime jr., by battle experience if the specimen knows Mimic. Despite its name, the mr. mime species is actually capable of being both male and female. Although it is difficult for this writer to admit, the name came from a notoriously sexist period of pokémonology and is based entirely on the misconception that only male organisms were capable of being terrible enough to manipulate impressionable humans into believing an object exists when it doesn’t until it does. As it turns out, both sexes of mr. mime do this, and the pokémonology community spent the ensuing sixty years pretending that the name came from an unfortunate translation error.
