** To start with, there's his whole character concept: he's the Spirit of Destruction, a strong embodiment of corruption, decay and annihilation. Worse, despite the film's otherwise {{anvilicious}} nature, he's ''not'' humanity's fault -- indeed, it's subtly implied that the devastation ''he'' caused when he spontaneously decided to emerge and cause a volcano to react and kill off some life thousands of years ago led to humanity going astray from being in union with nature, while doing one thing he does best - spreading toxins. So yeah, he ruined paradise and set off humanity's fall from grace, making him essentially {{Satan}}. He's somewhat of an OmnicidalManiac because he wants to destroy nature, just because he thinks it feels good as it "depresses and bores" him. His shape-shifting appearances are a variety of what's considered unsettling.

*** A possible logical explanation for this is that the laboratory was carrying out multiple tests and Batty is either remembering snippets of dialogue he heard in passing related to experiments on other animals, or was unfortunate enough to have gone through '''several''' studies himself. Both options are still quite sobering, as the latter puts Batty's suffering in a whole new context, and the former is a very chilling reminder that Batty is lucky that he was ever able to taste freedom again.

* Hexxus -- just... where do we ''begin'' with Hexxus?

** When he's first released from his prison, it's in the form of a shapeless mass of oily gunk, something vaguely serpentine that seeps, squirms, and crawls its way through the leveler's innards. It's just nauseating, ''especially'' when it takes a moment to suck effluence from the leveler's pipes, slurping and bulging obscenely as it does. There's something subtly creepy about its amorphous form that hints of the true danger ahead.

** Then, having fed enough, Hexxus decides restore his former glory. This takes the form of a ''skeletal arm ripping out of his blob form'' out of nowhere, joined by a second such arm. These clutch onto pipes and [[Film/{{Hellraiser}} haul a slime-dripping, jet-black human skeleton partially out of the puddle of muck]]. This gooey bone form jolts as electricity arcs across it, then explodes in a cloud of smoke -- out of which then pushes a smog-like lantern-jawed humanoid.

** As the film advances and the leveler feeds, Hexxus keeps on getting bigger. And bigger. And ''bigger''. His smog-genie form isn't so bad on its own, but when it's turned into a stories-tall monstrosity gloating as the jungle around him is destroyed, it's surprisingly freakish. No wonder the leveler's crew split when his gigantic mug leers at them through the front windscreen.
** Finally, when our heroes shut off the engine and end the flow of smog, Hexxus reaches deep into the depths of the leveler and dredges up all of its oil and grease to go OneWingedAngel. In a mass of eerie, purple-hued flame, an ''enormous'' mass of sludge erupts out of the leveler, fire rippling around its base and billowing through its core. This then resolves into a giant black abomination, a naked skull and open ribcage contrasting muscular arms and covered in a shroud of dripping muck, fire bursting out of its eyes and mouth as Hexxus catches his breath. Flames blaze inside its ribcage, mouth and throat as it looks ''right at the viewer'' and gives them a gaping-jawed malevolent grin. And this form, pictured at the top of the page, is basically what Hexxus wears through the rest of the film.

** And then, finally, there's Hexxus' well-deserved death-scene due to his impulsive and vast threat, where he is ''consumed from the inside out'' by a tree magically coaxed to grow inside of him.

* The first tree that Hexxus is trapped in. It's a baobab tree without leaves, black in color, with gnarled branches, and a bulbous body; it's the floral equivalent of the UncannyValley. You can ''feel'' the evil festering inside of it just from seeing it on the screen. The music that plays when it's on screen helps too: loud horns, cymbals and an eerie ghostly wailing in the background. The unearthly wails continue even as the tree is being sliced into boards. Hexxus is a Grade-A [[EldritchAbomination Eldritch horror]], make no mistake.

He's an OmnicidalManiac who wants to destroy everything, seemingly just because he thinks it feels good.

** The more frightening thing is just the implication of the scene. Not two seconds after separating from Crysta (and only a few minutes after being shrunk) Zak runs into something that's ready to eat him, runs into several others throughout the song and is basically helpless. It's only at Crysta's insistence that the goanna lets him go because seemingly every animal in the forest respects the fairies, with Zak seemingly left unmolested by the animals after this only because he's always palling around with either Crysta or Pips from then on. If Zak didn't befriend the fairies (or worse he angered them and they choose not to protect him) he'd not have lasted 2 minutes in Fern Gully before being eaten by something. Kind of makes the place look terrifying.

** This is followed by his "Toxic Love" song number, which contains all manner of disturbing images, such as Hexxus splitting into multiple floating heads that then devour each other, a chainsaw-armed Hexxus tearing down a tree, Hexxus spewing fire over a leveled forest, and Hexxus laughing madly in the flames, even as fire rushes through him and out his own mouth.
