Pokedex Entries

Although it’s unclear why it collects keys, giving it a key makes Klefki very happy. However, it apparently only likes master keys.

Klefki Weakness

Klefki's Steel/Fairy typing leaves it vulnerable to Fire and Ground. It shrugs off Poison and Dragon-type attacks completely. It resists 9 types, so it can switch into a lot of moves safely. With 57 HP and balanced defenses, Klefki can afford to eat a neutral hit or two.
