Acid Launchers are the secondary weapons for Hornets on Lyoko. These launchers spray poisonous chemicals onto the ground that steadily depletes the life points of whatever it comes in contact with. It is capable of taking half of a person's life points with one exposure. The puddle of toxins also lets off a green mist that damages anyone in the area. This ability was only seen twice in Season 1 in the episodes, "Satellite" and "Swarming Attack."
