Mystery Dungeon series
Upon entering the floor, the Pokémon with this ability changes the weather to clear and negates all weather and keeps any weather from activating as long as the Pokémon remains on the floor, or unless the ability is suppressed. Attempting to change the weather will yield the message "The weather didn't change." If the last remaining Pokémon having this ability is knocked out or otherwise removed from the floor, the weather condition with the highest precedence will activate at the end of the turn. If Rain Dance, Sandstorm, Sunny Day, or Hail was used during that time, the one most recently used will activate.
