Entry hazards are field effects that punish opponents when they switch in. Stealth Rock deals damage based on the incoming Pokémon’s Rock-type weakness or resistance. Spikes and Toxic Spikes affect grounded Pokémon, while Sticky Web lowers the Speed of grounded opponents on entry. Hazards reward forcing switches and can gradually wear down defensive teams. They can be removed or prevented by game-specific moves, Abilities, items, and mechanics. Not every format or generation contains the same hazard tools, so check the current move availability. Team building should consider both setting hazards and handling the opponent’s hazards.
