Blissey

Using Blissey in a Playthrough

The Happiny line is built around extreme special durability and support rather than quickly defeating ordinary opponents. Happiny itself has extremely poor battle stats and is generally a developmental stage, while Chansey combines enormous HP and Special Defense with reliable recovery through Soft-Boiled and utility such as status, screens, and Seismic Toss depending on the game. Blissey improves the line's Special Defense and Special Attack while retaining its extraordinary HP, making it much less passive when good special attacks are available. Both Chansey and Blissey are exceptionally effective against special attackers but have extremely poor physical Defense, so physical Fighting moves and strong physical attackers must be avoided. Their slow damage output can also make routine playthrough battles cumbersome even when the opponent poses little actual danger.

Blissey in Competitive Pokémon

Chansey and Blissey are among the most historically important dedicated special walls in competitive Pokemon. Chansey became particularly formidable after the introduction of Eviolite, which boosts both of its defenses while it remains unevolved, and it combines that bulk with Soft-Boiled, Natural Cure, status, entry hazards, cleric support, or Seismic Toss depending on generation. Blissey cannot use Eviolite but has greater Special Defense and Special Attack and can hold other items freely, allowing it to fill a similar special-wall and support role with somewhat greater offensive presence. Natural Cure makes both difficult to cripple permanently with status, while their defining weakness remains extremely low physical Defense. Which evolution is preferable depends heavily on generation, available items, and format rather than Blissey simply replacing Chansey competitively.

Blissey in Nuzlockes

The Chansey line can trivialize battles dominated by special attacks because very few ordinary special attackers can overcome its enormous HP and Special Defense before it heals or wears them down. FireRed and LeafGreen community analysis is divided mainly because Chansey is extremely rare and difficult to catch in the Safari Zone, slow to train, and almost useless against strong physical attackers, but its favorable matchups against special opponents can be extraordinarily safe once obtained. Soft-Boiled, Seismic Toss, Toxic, screens, and other support moves can let it defeat dangerous bosses without exposing frailer teammates. Blissey improves the line further when high-friendship evolution is available, although neither evolution should be mistaken for a general-purpose tank because strong physical attacks can overwhelm them very quickly.

Blissey can sense sadness through its fluffy fur and will rush toward people or Pokemon that are ill or distressed in an attempt to nurse them back to health. The egg carried in its pouch is described as inducing happiness and kindness in those who eat it and can even calm highly aggressive Pokemon. Blissey is rarely encountered in the wild and is primarily associated with populated environments. In Pokemon Legends: Arceus, wild Blissey provide a direct behavioral example of the species' caregiving instinct by approaching an injured person and remaining nearby until that person has recovered.
