The torch is the weapon used by Explorer Zombie, its upgrade, its Chinese counterparts, and Torch Juggler Zombie. It can instantly burn any plant it touches, but can be extinguished by Iceberg Lettuce, Snow Pea's and Winter Melon's projectiles, Hurrikale's wind, Power Snow and Cold Snapdragon's breath. In the Chinese version, Cryo-shroom can also extinguish its flame. For Torch Juggler Zombie, the torch does not burn the plant it touches. Instead, they would slowly damage the plant. Extinguishing it will earn the player the No Smoking achievement.
- For more strategies, see Explorer Zombie.
Ice-based plants can extinguish the torch. However, it should be noted that fire damage from Snapdragons, fire peas from Torchwood or Fire Peashooter, fire from Pyro-shroom, and Pepper-pult's fire peppers will relight the torch if it has been extinguished.
- Porter Gargantuar also carries a torch, but it does not burn plants, as it is not lit.
- Instead, it uses the unlit torch to smash plants. The torch is lit in the Lost City Part 1 trailer and in the Almanac image before the 3.9 update.
