The first dark plant seen in the series was the dark eco plant, a massive monstrosity that had tapped into some dark eco drums deep down in the Forbidden Jungle's temple. Its roots then spread through the temple and surrounding area, until it was killed by Jak. It is unknown why this plant did not appear like any other seen dark plants. In the Precursor Basin Jak encountered a batch of infected plants. He restored them to normal health using green eco and the A-Grav Zoomer in the mission "Cure dark eco infected plants".
