Badly Poisoned
The Pokémon is badly poisoned. It loses increasing HP each turn (1/16, 2/16, 3/16, ...). Damage resets when switching out.
Burn
The Pokémon is burned. It loses 1/8 of its max HP at the end of each turn (1/16 before Gen 7), and its Attack stat is halved.
CHANGELOG
- ›Damage per turn increased from 1/16 to 1/8 max HP starting Gen VII.
- ›Attack penalty has applied since Gen I.
Freeze
The Pokémon is frozen solid. It cannot act. There is a 20% chance to thaw each turn. Certain moves also thaw the user.
CHANGELOG
- ›In Gen I, Freeze had no natural thaw chance and was effectively permanent until hit by a thawing move.
- ›Gen II introduced a per-turn thaw chance (20%). Fire-type moves thaw the target from Gen V onward.
Paralysis
The Pokémon is paralyzed. It has a 25% chance of being unable to move each turn, and its Speed stat is reduced by 75% (25% before Gen 7).
CHANGELOG
- ›Before Gen VII, Speed was reduced to 25% of normal (×0.25, a 75% reduction).
- ›From Gen VII onward, Speed is reduced to 50% of normal (×0.5), making the penalty less severe.
- ›Chance to be fully paralyzed changed from 25% to 0% in competitive formats; game mechanics still apply.

CHANGELOG
- ›Sleep lasted 1–7 turns in Gen I–III. Reduced to 1–3 turns from Gen V onward.
- ›In Gen I, switching out a sleeping Pokémon reset its sleep counter.
Confusion
The Pokémon is confused for 1–4 turns. Each turn there is a 50% chance it hits itself for typeless damage (40 base power) instead of acting.
CHANGELOG

- ›From Gen VII, confusion self-damage uses a separate damage formula (roughly halved effective power).
