The green eco lurker, also known as the dark eco lurker, is a lurker-like enemy in The Precursor Legacy. They were created by Gol Acheron and Maia Acheron, being one of the only lurkers known for certain to be artificially created. These creatures were created when Gol and Maia's Precursor robot fired green eco into an open dark eco silo. They are large, spiky, lurker-like creatures, bearing the color of dark eco. They are very hostile, as they charge Jak to try to kill him.
