Hexxus

Hexxus is the main antagonist in 20th Century Fox's 1992 animated feature film FernGully: The Last Rainforest. He is the dark and evil spirit of destruction and pollution.

He was voiced by Tim Curry, who also played General Von Talon in Disney's Valiant, Pennywise/IT in Stephen King's IT, Drake in Don Bluth's The Pebble and the Penguin, El Malefico in Mucha Lucha!: The Return of El Malefico, Belial in The Legend of Atlantis by Golden Films, Dr. Frank-N-Furter in The Rocky Horror Picture Show, Maestro Forte in Disney's Beauty and the Beast: The Enchanted Christmas, and Ben Ravencroft in Scooby-Doo and the Witch's Ghost.

Overview
Hexxus is the evil spirit of destruction who embodies everything that is toxic to nature. As such, his only goal in existence is to cause destruction, decay and death in any way he can. It can be inferred that Hexxus' ultimate goal is to inevitably kill off all of the Earth's creatures by transforming the world into an uninhabitable toxic wasteland after he has taken complete power and control over it as the primordial embodiment of destruction and pollution. He will also stop at nothing to exact his revenge on the fairies of FernGully for his imprisonment by means of manipulating humans to help him in his evil plan.

Origin
Hexxus first appeared on Earth in ancient times when the balance of nature shifted. He rose out of the Earth and rained down his poison, destroying much in his wake and killing countless living creatures everywhere in FernGully, including humans, who fled in fear, never to return. He was finally defeated by the elderly and wise fairy priestess named Magi Lune, and was imprisoned inside an enchanted baobab tree, which he remained trapped in for hundreds, if not thousands or possibly even millions of years.

FernGully: The Last Rainforest
While painting red "X" marks on trees, marking them for cutting, the movie's male protagonist named Zak comes across the tree that Hexxus was imprisoned in, he finds it creepy, much like the entity it contains. While he is looking at the tree, Zak is bugged by a fly, and while trying to hit it with his aerosol can, he ends up marking the tree. That evening, the mobile lumbermill known as "The Leveler", driven by Zak's superiors named Tony and Ralph, cuts down the tree.

As the cutting begins, the Leveler shakes violently, likely due to Hexxus' supernatural presence, but the lumberjacks ignore the signs and cut it down anyway. The tree is processed and reduced to sheets of wood by the Leveler, releasing Hexxus in a slimy form. Chuckling maliciously, he almost immediately begins absorbing energy from the Leveler. And by the next day, he has regained enough strength to quickly move around and coherently speak. While wondering how he escaped, Hexxus quickly realizes it is the work of humans. Determined to get revenge upon the fairies of FernGully for imprisoning him and seeing the most useful potential of the human machine, Hexxus initially decides to take control of it and use it to exact his sinister plan.

Under the outspoken and vocal guise of their boss, Hexxus occasionally manipulates the lumberjacks into tearing down the rainforest in the direction of FernGully by the next morning, thereby destroying the very fabric of their world. He then assumes his ghostly main form, singing the song "Toxic Love", before going to the Leveler's roof to oversee progress as he laughs maniacally. Sometime later, upon reaching FernGully after having successfully destroyed much of the rainforest, Hexxus reveals himself.

With Magi Lune gone (having sacrificed herself to give her power to all of the other fairies), it is up to Crysta and the other fairies to defeat him once and for all. He and the Leveler chase the fairies and drive them into their home tree, despite Crysta's efforts to stop his advance. Zak (knowing the fairies cannot stop the Leveler) has Batty take him to the machine's cab, from which he can stop it. However, Batty gets carried away and flies right up to Hexxus, who laughs and violently swipes at them, sending debris raining down onto Batty, who drops Zak onto the windshield as a result.

As Zak frantically tries to get the lumberjacks' attention, Hexxus immediately scares them off and takes control of the machine himself. As he proceeds to the fairies' home tree, he closes off the Leveler's cab to keep out intruders, but Zak still manages to get inside with Pips' help. Just as Hexxus is about to kill off all of the fairies, Zak turns off the Leveler, causing Hexxus to lose the energy that he was gaining from it and disappear. However, he reemerges moments later, this time in the form of a giant, demonic, fire-breathing skeletal beast made of oil.

Crysta remembers a bit of advice that Magi gave her before her death, so she takes a seed and flies up to Hexxus. Unfortunately, he devours her as he laughs evilly, to everyone's horror. However, as he prepares to destroy FernGully for good, he begins sprouting branches like a tree. Annoyed, he rips off the sprouts, but the emerging new tree continues to grow. Pips (realizing what is happening) leads the fairies into helping the new tree grow, within moments, Hexxus and the Leveler itself are overrun. Hexxus can only watch in terror as he is sealed within the closing roots, imprisoning him presumably once and for all, so that he may never harm FernGully again.

After his defeat, Crysta and Batty are revealed to be alive, while Zak (knowing human development can still threaten FernGully) returns home with Tony and Ralph with a new environmentalist mindset.
