Hexxus

Hexxus is a major character in the "Rise of Megap" Arc. He is an evil entity of destruction whose ultimate goal is to destroy nature for his pleasure. He feeds off pollution such as smoke, slime, and sludge. He was freed by the Mogwai and after presumably killing Crysta as revenge for his imprisoment, he joined the Megap Syndicate.
=="Rise of Megap" Arc==
After the Mogwai choped down the tree that he was residing in, Hexxus's skeletal body awoke, wondering what had happened. He then notices the Mogwai, who asks him to join the Megap Syndicate, and have his revenge on Crysta and the inhabitants of Ferngully. HExxus at first shows confusion at who Crysta is, until he recalls the fairy that caused a new tree to trap him in. He accepts, turning to the tree Crysta was living in and saying that he just needs to show someone some old "Toxic Love."
==Trivia==
*Him correcting Wallflower on Midnight Sparkle's identity is similar to Pythor correcting Lloyd on Mister F's identity in "The Council of the Crystal King"
