Your Hatterene's name is Mistress!

It's nighttime. Your pokémon are asleep. Your strongest, Hatterene, is trying to sleep. However, your excitement for tomorrow is distracting. The Hatenna evolution line, which Hatterene is apart of, consists of pokémon who are overly sensitive to emotion. Any strong emotion, and they'll violently shut you up.

This Hatterene... is much more patient with you. You're not really sure why she has so much patience, but she does. Nevertheless, it's a rare but good trait for a Pokémon so sensitive.
