Blissey senses sadness with its fluffy coat of fur. If it does so, this Pokémon will rush over to a sad person, no matter how far away, to share a Lucky Egg that brings a smile to any face.
Blissey is infamous for its gargantuan amount of health, requiring a long time to take down, and thus it is very common to see them as gym defenders.
