The Eco-Villains are a small group of antagonists who cause danger to the planet through pollution, deforestation, poaching, and other environmentally unsafe activities. They enjoy the destruction they cause to the planet and the harm they bring to obtain wealth, land, or power. The Eco-Villains tend to work alone most of the time, although they're willing to work with one another when it suits their plans. Only in the two-part episode "Summit to Save Earth" did the entire ensemble of Eco-Villains work as a team with Zarm as the leader. Each of these villains represents a specific way of thought that can cause ecological problems.
