When Trees Attack

Go To
Mobile, quasi-sentient-and-upward trees aren't necessarily evil, but they're often hostile, because that's scary.

This is the third type of tree listed in Diana Wynne Jones's The Tough Guide to Fantasyland. Variations include, as quoted from the book:

  1. Prehensile. These will grab you with their branches and try to eat you.
  2. Mobile. These will quietly move about and get in your way. They may also try to eat you. In extreme cases they will attack buildings.
  3. Poisonous. Avoid any drippings from these.
  4. All these things at once. Run away.

These tend to contribute to Gaia's Vengeance and may populate The Lost Woods. A Plant Person or someone with a Green Thumb may summon these in battle. When facing these, killing it with fire is recommended. A good source of Paranoia Fuel: as something innocuous you see all the time, it really shouldn't be fighting.

Moreover, if you think about it, the concept of a mobile, fighting tree is actually a lot more worrisome than it might sound. For one thing, humanity has built a lot of stuff out of wood — like houses and boats. Notice a common theme? Those things are built to last. (And likely, a sentient tree won't be too happy knowing humans turn its kin into chairs...) Imagine a being, made entirely out of that substance, who dislikes you and has strength proportional to that toughness. An ambulatory tree would pack one hell of a punch — and that's not even taking into account how much the thing would weigh, or the sheer number of limbs (in both senses of the word) they have, or how it would be almost impossible to harm due to it simply lacking organs, bones and blood...


Hostile trees are also a source of humor, partly because of the absurdity of something seemingly so innocuous and ignorable striking fear into the hearts of men, and partly because "tree" itself is a mildly Inherently Funny Word. If you're lucky, they'll turn out to have more bark than bite.

Compare Plant Aliens and Treants (which need not be hostile, but fit this trope when they are) and Man-Eating Plant. If you see lots of these as Plant Mooks, it might indicate that you are in Mordor or a Garden of Evil or on a Death World. If your trees are attacking you, it may be a sign that they're epileptic. Or not...

  • In a "Fruitsnackia" commercial, various sentient fruit-snacks are sitting by a campfire next to a huge fruit snack tree. A fruit snack snake slithers out of the tree and they freak out. A fruit snack bear comes out of the forest, eats the fruit snack snake and roars. The roar apparently wakes up the fruit snack tree who then promptly eats the fruit snack bear. The fruit snack campers breath a sigh of relief. Their lives are saved right? Not quite. The fruit snack tree blows out the campfire, leaving us with the sight of the trees' eyes and toothy grin and the campers' terrified eyes.

    Anime & Manga 
  • Godzilla Earth from Godzilla: Monster Planet is, unlike other Godzillas, a botanical-based organism, and has ruled the planet for 20,000 years after driving humans off of its surface. When they do come back, they battle him and manage to destroy him with explosives, only to find that the Godzilla they fought was a relatively tiny offspring, and the real Godzilla had grown to the size of a mountain!
  • At the beginning of the Lost Children chapter of the Retribution arc from Berserk, Guts encounters a tree that had been used as sacrificial grounds for so many years the faces of the dead appeared on its trunk. At night, it awakes and wreaks havoc upon the bandits who'd been camping underneath it due to the presence of Guts' brand.
  • An evil Heaven's Day tree serves as a Monster of the Week in one episode of The Big O.
  • Ent monsters are rather common in the world of The Death Mage Who Doesn't Want a Fourth Time, and their wood serves as pretty solid building material. Vandalieu accidentally creates his own Ents with his magic while building an orchard, and the most prominent Eisen, evolves into a drop-dead gorgeous Plant Person.
  • Several mon species in Digimon - the most prominent are Cherry/Jureimon, noted for persuading Matt/Yamato to turn against Taichi in Digimon Adventure, and the generic mook species Woodmon, from which Cherrymon evolves.
  • A group of evil trees appear in the Grimm's Fairy Tale Classics episode "Jorinde and Joringel" — brought to life by the witch who holds Jorinde hostage. The trees chase Joringel through the woods. When he loses sight of them and thinks they are gone, one of them sneaks up behind him and eats him. Luckily, it's revealed to be All Just a Dream as Joringel wakes up in a bed right after the tree eats him.
  • InuYasha:
    • Also by Rumiko Takahashi, the anime (at least) has Ninmenka, a youkai in the form of a peach tree who devours humans, particularly favoring the flesh of sages. Possibly based on a creature from real Japanese mythology, this charming demon is also referred to as the Tree of Human-Faced Fruit, which may make it a distant relative of the Death's Head Tree of Dungeons & Dragons. The name comes from its fruit, which bare ugly human faces in response to all the people it has eaten. Humans can eat these disgusting things to gain demonic power and longevity, and a Ninmenka that has eaten enough sages can produce a fruit of true immortality.
    • A less hostile tree youkai named Bokusen'on also appears once in the series to give some exposition on Inuyasha's full-demon side. Though peaceful, he's presumably still pretty badass since his branches were used to craft the unbreakable sheaths of Tessaiga and Tenseiga. He's also how Myoga passed Tessaiga to Sesshomaru... by hanging it on Bokuseno'on's face, the coward.
  • The ending of "Splatter Film," a short manga by Junji Ito, features one of these. The characters become addicted to some strange "honey", only for each one of them to be squashed flat whenever they try to eat any of it. The narrator travels to a distant jungle to find more of the stuff, only to discover it's not actually honey at all-it's the sap of a bizarre tree that can teleport its branches around the world to swat anyone who tries to eat its sap.
  • One of these appeared in the first season of Magical Girl Lyrical Nanoha and had the misfortune of facing both Nanoha and Fate at the same time. It died a quick death.
  • In Naruto the original form of the Ten-Tails is the World Tree. It became a rampaging Beast after its Chakra-laden fruit was stolen by a woman who wanted to use its power to end war. It reverts to its original form during the Final Battle.
  • In the Negima!? Neo manga, the first Star Crystal-based Monster of the Week takes the form of a prehensile tree that captures Konoka.
  • In One Piece, the Seducing Woods is made up largely of mobile, sentient trees. The forest got its name in that it lures visitors in with its smells of desserts and appealing look, then traps them in there by having the trees move about so the visitors never escape. When some of the Straw Hat Pirates find themselves in the Seducing Woods and discover the secret (that the trees are mobile), their immediate solution is to destroy as many of these trees as possible so as to limit the trees' capacity to trick people.
  • In Origin: Spirits of the Past, the Genius Loci forest uses freaking DRAGONS composed of foliage to attack its enemies.
  • A tree-based Monster of the Week appears in every installment of the Pretty Cure franchise.
  • A cursed cherry tree in the Kunō Family Estate in Ranma ½. When Kunō tries carving his name and that of the "pigtailed girl" on its trunk, it comes to life and absorbs him, leaving him as a man-faced ambulatory tree that hunts down any pigtailed girls to ask them for a date.
  • The Makaiju (The Doom Tree/Tree of Life for the Dub Watchers) from the Sailor Moon anime. In the same arc, the keepers of said tree also send out a Cardian that takes on various characteristics of a cherry tree, and lurks within one before striking. A tree from Rei's shrine also becomes one when infused with a Demonic Seed thanks to Kaolinite and transformed into a daimon named Mikuji.
  • Yggdrasil in Undefeated Bahamut Chronicle, though mostly in the original light novels (in the anime, it resembles a giant skull with branches sprouting from it). It has an incredible variety of dangerous abilities, including regeneration, adapting to resist any attack and grow even stronger, eating Drag-Rides to incorporate their weapons for its own use, and implanting its seeds into people to strengthen and control them. It can be controlled and is used by the villains on the two occasions it appears.
  • Yu-Gi-Oh!: Capsule Monsters: Yugi and Celtic Guardian get attacked by an entire forest. Fortunately, he's able to Kill It with Fire.
  • The Sinning Tree in Yu Yu Hakusho, a demon tree that traps its prey in an Ironic Hell until it has drained all of its life force. Kurama uses this on the Nigh Invulnerable Elder Toguro to give him a Fate Worse than Death.

    Asian Animation 
  • Motu Patlu: In "Time Machine", while Motu and Patlu are in the Stone Age, they are attacked by a big tree with a face.

    Card Games 
  • Magic: The Gathering: Aggressive plants of various types are a staple of Green, the color of the natural world.
    • The Treefolk, Dryad and Plant creature types, while not inherently hostile or homicidal in the game's lore, are most often represented this way due to the game's focus on battling. One specific treefolk, Crabapple Cohort, has flavor text detailing it exacting its revenge upon people who picked its apples. Some elementals also end up in this area.
    • There are various creatures and spells — such as Awakener Druid, Rude Awakening and Liege of the Tanglenote  — that, while not walking trees themselves, can turn lands you control into vengeful armies of creatures that can curbstomp dragons and eldritch abominations. While any land can be turned into this, the Green nature of these cards generally implies the animation of forests.
    • Stirring Wildwood, in which the entire frakking forest snatches your pteranodon rider out of the air and smashes it into the dirt. Unlike other such cards, it does not need an outside trigger to do this, but can “awaken” itself of its own accord.

  • In the "Atomic Knights" stories in DC Comics (mostly in the Strange Adventures title), a botanist in the post-World War III world found a large species of bird's-foot trefoils (a bean-producing plant) that could walk around, communicate telepathically, and obey commands. Unfortunately a mishap convinced them humans were their enemies, and they fought back. They could also throw pods that burst with poisonous gas.
  • In Soulsearchers and Company #5, the Soulsearchers are attacked by grove of sentient, semi-mobile trees known as the Parliamentrees when they are travelling through the fairy tale forest.

      Snoopy: Sometimes I think that as soon as I hit a shot, a tree runs out and stands in front of my ball.
    • The Kite-Eating Tree is usually just a tree that Charlie Brown has the bad luck of continuously getting his kite caught in, but sometimes it is shown literally eating the kites, thinking to itself, and grinning. While the Kite-Eating tree does seem to sadistically enjoy eating Charlie Brown's kites, eventually Charlie Brown seems to enjoy it once he realizes that he's the only kid in the neighborhood who flies them and without him the tree would starve.
    • See the Robot Chicken entry below.
  • The Far Side:
    • One strip has a logger getting grabbed by a grove of trees, who start arguing about what they should do to him (such as cutting him in half and counting his rings).

  • The Twilight Child: One chapter briefly features a walking tree... made of custard. Which tries to eat ponies. Discord is responsible for this one. The fact that it's made of custard is what gives the pony who deals with it the most difficulty.
  • A Minor Variation: Twilight Sparkle is in constant connection with plants, and can therefore do this when she wants to. It even extents to dead wood, allowing her to animate Ponyville's town hall at one point.
  • My Little Praetor: Twilight Sparkle's library winds up getting turned into a shapeshifting monster.
  • In Tealove's Steamy Adventure, the final Giant Mook the heroes face is a mobile pear tree. Which inspires the line: “Cower! And dis’ pear!”

  • Some living trees show up in Prince Charming's army in Shrek the Third.

    Films — Live-Action 
  • Evil Dead:
    • The infamous Rape Trees from The Evil Dead (1981) that attack one character and start ripping her clothes off. Sam Raimi has since said he went too far with that.
    • The evil-possessed trees return in more violent, but less lusty, form in Evil Dead 2: the whole forest eventually comes to mobile life and lays siege to the cabin in the woods.
    • In the remake, Mia is bound and choked by the trees, leaving her badly injured but not raped. She is instead raped by the Deadite itself, which looks like a giant thorny leech and enters through her nethers.
  • The M. Night Shyamalan movie The Happening involves killer trees. They are releasing a neurotoxin that makes people violently suicidal.
  • There is an evil tree demon in A Chinese Ghost Story.
  • In the 1966 Z-grade production The Navy vs. the Night Monsters, the eponymous Night Monsters are mobile tree stumps that secrete acid.
  • In The Wizard of Oz, Dorothy and the Scarecrow pass through an orchard of apple trees — possibly created (or animated) just then by the Wicked Witch.note  Squeeing in delight, she picks one only to have the tree slap her. Challenged by the tree, she starts explaining, and all the trees start talking at once. The tree that slapped her gives the page quote. Then the Scarecrow (the smart one of the group) tricks them into throwing apples at her, by snootily insulting them and disparaging their apples. Dorothy gets the apples, and in the process, discovers the Tin Woodman.
  • The living killer tree in Poltergeist. It almost ate a kid for goodness sakes!
  • From Hell It Came: The entire movie is about an evil and (barely) ambulatory tree.
  • The short horror/comedy film Treevenge is about a group of vengeance-happy Christmas trees.
  • Cthulhu. The protagonist nearly runs over something on a backwoods road at night, but we only see a glimpse of a spooky leafless tree. A similar creature later tries to reach him in his prison cell — these scenes were however cut to a minimum due to Special Effect Failure. Presumably the creature was meant to be Shub-Niggurath (The Black Goat of the Woods with a Thousand Young) from the Cthulhu Mythos. Most likely it was meant to be one of Shub-Niggurath's Dark Young, as they are usually described as looking like walking leafless trees, only the "branches" are actually tentacles.
  • The Annette Funicello version of Babes in Toyland featured Gumps, animated trees with faces who captured travellers in the night and escorted them to the Toymaker.
  • The Guardian (1990) featured a dryad-like witch who sacrificed babies to a living tree. One scene featured chainsaw wielding guy going mano-a-treeo and winning.
  • The Harry Potter films contain the Whomping Willow, for obvious reasons. See below in Literature.
  • In Jumanji, one of the game-cards causes giant plants with grappling tentacles to spring up and spread out across the neighborhood. We don't actually see them catching people, but one did drag off a police car. Later a poisonous barb shot from it fatally wounds Judy.
  • Little Shop of Horrors has Audrey II as the main foe. Though not quite a tree, the potted plant is easily the size of one by the time all is said and done.
  • In the parody film Trees, a 'Great White Pine' serves the same role as the shark from Jaws in killing and attacking people. And apparently, this isn't an uncommon creature...The sequel, Trees 2: The Root of All Evil also has killer Christmas Trees attacking the town.
  • Womaneater had a man growing a human-eating tree in his basement and true to the title, fed women to it.
  • The Ruins had killer vines that grew more ridiculous over time. Before long they were able to mimic sex noises to inject paranoia into the couples.
  • In Big Fish, Edward is attacked by trees while walking on the path in the forest alone on a road which had a warning sign, but he knows he doesn't die that way, so they let him go. He ends up in the town of Spectre right after that.
  • Morozko. Baba Yaga has her army of attacking trees, who are a bit cowardly.
  • In The Cabin in the Woods, one of the options for monsters that could have attacked the heroes was "Angry Molesting Tree". Later, when all the monsters break loose, we see the branches of one grab a guard and pull it offscreen, presumably to stick its sticks where they don't belong.
  • In The Brothers Grimm, violent perabulatory trees are one of the many hazards in the forest.
  • In The Lord of the Rings: The Two Towers:
    • Treebeard and the Ents are walking, talking trees (tree shepherds). When Saruman's troops tore down a sizable portion of the nearby forest for fuel, the Ents destroy his entire operation in a few hours.
    • The Huorns in the Extended Edition clean up the Uruk-hai survivors of the Battle of Helm's Deep brutally and effortlessly.
  • Groot in Guardians of the Galaxy is normally a Gentle Giant tree, but if you make him angry, he will become a most dangerous one.
  • In The Last Witch Hunter, trees are prominently featured as villains' theme of sorts - Belial's teleporter looks like tree roots, the Witch Queen uses tree branches as Combat Tentacles and the Black Death-spreading Plague Tree is, obviously, a tree.
  • Maleficent has Maleficent call on the forest she lives in to help her fight a human army, which causes a number of tree-men, tree-boars, and a tree dragon to come out and kick the humans' asses.
  • Contamination .7, aka The Crawlers, aka (purely for marketing purposes) Troll 3, features a variant in which the accessible, visible part of the tree is harmless: it's their roots that have achieved mobility and strangle, crush, whip, or grow right through hapless victims.

  • In the Star Challenge book Mysterious Moons, a Negative Space Wedgie can send you to Andromeda. If you end there you may find plant-like aliens, unhappy because you mined for fuel their planet and who state that mitochondria are actually entities that control lifeforms that have them.
  • The Choose Your Own Adventure book "The Magic of the Unicorn" features an ent-like witch of the woods in one of its bad endings.
  • Plenty in the Fighting Fantasy series, from hostile Tree Man which attacks players with its two main branches, to blood-sucking strangleweeds and plants with vines that sneaks up and choke the player.

  • The Lord of the Rings:
    • The Ents, though they aren't so much overtly hostile as simply reclusive. They do get pretty riled up over Saruman cutting down their ancient forest to fuel his war machines. They also tend to distrust dwarves for carrying axes. To give you an idea of how badass the Ents are — Trolls, one of Sauron's stock Giant Mook troop types, are corrupted imitations that are weaker versions of Ents.
      Pippin: It was staggering. They roared and boomed and trumpeted, until stones began to crack and fall at the mere noise of them [...] Round and round the rock of Orthanc the Ents went striding and storming like a howling gale, breaking pillars, hurling avalanches of boulders down the shafts, tossing up huge slabs of stone into the air like leaves. The tower was in the middle of a spinning whirlwind. I saw iron posts and blocks of masonry go rocketing up hundreds of feet, and smash against the windows of Orthanc.
    • Then there's the Huorns of Fangorn Forest; they're otherwise ordinary trees that have partially awakened and become "entish" — they drag dark mist around them, so you can't really see them move, but from the descriptions it seems that they have the speed of a bullet train when they get riled, and they are quite capable of annihilating an entire army of orcs without trouble.
    • Old Man Willow, an ancient tree living in the Old Forest near the Shire, is implied to be a particularly nasty Huorn, though he may just be a different being of a similar type, since he seems to have supernatural powers wider in range and scope than a typical Huorn... or else just a greater inclination toward evil. The other trees of the Old Forest are just as hostile, if less active — they deliberately try to get travelers lost in the forest, sway and whisper to each other even when there's no wind, and at one point tried to invade Buckland by planting themselves close to the protective hedge on its border so they could lean over to the other side until the hobbits cut down and burned them.
    • According to Tolkien's letters, he partly created the Ents and Huorns because he was disappointed in the way Birnam Wood travelled to Dunsinane.
  • 'The Illearth War'' features Caerroil Wildwood, a sort of male Dryad. Fleshharrower's army is eventually swallowed up by the forest under his command. Since The Land is in many ways a darker, edgier version of Middle-Earth, unlike Fangorn he demands a price for his assistance.
  • The Whomping Willow from Harry Potter. Harry and Ron learn this the hard way in Chamber of Secrets when they crash Arthur Weasley's Flying Car into it. It comes up again in Prisoner of Azkaban when the Dementors make Harry fall of his broomstick during a storm — it ends up flying into the Willow, which tears it apart. Lupin mentions that it was planted during his own schooldays because he is a werewolf, and the tree was to conceal the tunnel he used to get to the Shrieking Shack every full moon where he could safely transform. Students used to play a game where they saw how close they could get to it — this stopped after one of them nearly lost an eye.
    Snape: ...And you did considerable damage to a Whomping Willow.
    Ron: Honestly, sir, I think it did more damage to us.

  • The living tree in The Last Unicorn.
  • Monica Hughes's Space Trap has a whole living forest, kind of a Hive Mind.
  • A certain species of tree in Nyissa in the Belgariad. Not only is the fruit lethal and the bark poisonous to the touch, but the tree itself takes a sadistic pleasure in luring unsuspecting victims and feeding on them. Ce'Nedra, a dryad, collapses screaming in horror when she reads its thoughts. Polgara makes a point that systematically burning trees like that one is one of the very few things she and Salmissra agree on.
  • The Tangle trees from Xanth.
  • The Venom of Argus by Edmund Cooper features an alien tree with long tentacles that harpoon prey and take it to the tree's mouth to be swallowed and eaten.
  • Men in Black: The plot of the Expanded Universe novel The Green Saliva Blues involved the Zahurians, tree-based aliens that vacation on Earth and feed on just about any flesh-based life form, slicing up the creature (or person) with their roots and absorbing everything. Amusingly enough, the light from the Earth's sun was dangerous to them, as it eventually turned them into real trees (plum trees!).
  • The shambler trees (actually a mutually-supporting ecology of plant-like creatures) in the sci-fi series The War Against the Chtorr. The shambler tree and its carnivorous tenants harvest an area, then move on at a rate of a kilometre a day. "A Season for Slaughter" goes into unsettling detail explaining how such a tree could walk (it has to virtually become an animal) and how it feeds.
  • In Dan Abnett's Gaunt's Ghosts novels, the trees of Tanith were mobile, although very slow; the danger was that no path would remain in place. This is suggested to be Chaos taint. Although Tanith was lost the day the regiment Gaunt's Ghosts, Tanith First and Only, was founded, its member make marvelous scouts because of their ability to manage in these woods.
  • One Sesame Street book featured Cookie Monster discovering a cookie tree and trying to eat its cookies. The tree then grabbed him and menaced him until he apologized for being greedy.
  • In Dan Abnett's Warhammer 40,000 Horus Heresy novel Horus Rising, the planet Murder has trees on which the aliens throw dead bodies before they eat them. The trees themselves cause horrific storms that trapped a company of Space Marines on the planet. Fortunately, one Marine was so horrified by the desecration of the corpses that he blew up some trees, causing the storms to die down and so revealing they were behind the storms.
  • The Day of the Triffids.
  • G. K. Chesterton has a short fairy tale (The Tree of Pride) that tells of a time when all trees were this way. Then one of them started to eat the birds that nested in it...
  • Deathworld had the entire ecosystem of Pyruss being hostile. The brain bits seemed to be some overly psychic plants. Blowing them up just made the ecosystem angrier.
  • Trees in the Forest of Skund in Discworld can talk. They're not dangerous, just really, really annoying.
  • The path to Mordaga's lair in The Elric Saga is protected by a grove of 49 Elder Trees, each of which holds an imprisoned soul. When anyone approaches, the trees release countless leaves which drift toward the intruders, latch onto their flesh, and start sucking their blood. The trees can also lash out with sharp, sturdy branches.
  • In the second book of The Cleric Quintet, Cadderly is able to convince the elves to attempt the ancient and nearly forgotten ceremonies to awaken the trees so as to battle the orc invasion. Needless to say, the ceremony works. Unfortunately, the enemy quickly realizes that the trees are like siege towers, powerful and huge but also slow and flammable.
  • Though not really trees, and not mobile, amphistaff polyps in New Jedi Order are living creatures purpose-bred by Yuuzhan Vong shapers. They're (multi-)armed with flexible, blade-edged limbs, can spit venom, and eat just about anything. Their seeds/limbs are harvested by the Vong as personal weapons.
  • Alan Dean Foster's works:
    • In the Humanx Commonwealth series, several nasty variations of this trope populate Mid-World.
    • In the Spellsinger series, the giant mushrooms of the Muddletup Moors prey on travelers with an empathic attack, then absorb their nutrients as they decompose.
  • The first section of William Hope Hodgson's The Boats of the "Glen Carrig" involved a land full of prehensile-branched flesh-eating trees. H. P. Lovecraft himself called Hodgson a master of scary writing.
  • Due to the war with the faeries, the world of Bones of Faerie is filled with enchanted trees and plants that try to attack and kill humans.
  • David Drake has a thing about killer plants. The Jungle and Redliners both feature trees that will try to kill you in one way or another; in fact, there are several different ways a tree can kill in Redliners, including exploding to fling out armor-piercing spikes, spraying those who come too close with a fast-hardening (and acidic) sap, the bark turning out to be tentacles....
  • In Patricia A. McKillip's The Book of Atrix Wolfe, an oak tries to bury Talis underground.
  • One of the stories about Jakub Wędrowycz features sentient walnut trees. They can't move, but due to radiation from the Chernobyl incident their walnuts have mutated into brains, so they can communicate via Telepathy and Mind Control people, and intend to Take Over the World. They try to enslave the protagonist, but he slyly slips them some weedkiller, then comments that their plan was doomed to fail within a few months anyway — walnuts fall off in winter.
  • In Sergey Sukhinov's Castle on Venus (part of the 21st Century Chronicles series), there is a forest of alien trees on Venus, theorized to have being brought there by a comet. Some of these trees are able to uproot themselves and act as animals. They are not sentient, though. While they are non-carbon-based, they don't shy away from trying to consume humans. Sure, they spit them out after determining that we don't taste right, but it's usually too late for the poor victim. The trees are very aggressive and attempt to destroy any manmade structure, including the road that goes through the forest. One of the popular vacations on Venus is the safari, which involves seeing and, possibly, hunting some of the animal-trees.
  • The willow trees of Chronicles of the Kencyrath can move autonomously much like the Old English legend. They generally don't attack humans, but do cause a fair amount of collateral damage including one poor soul who has a willow wand try to root itself in his flesh.
  • Killer trees show up in several of the stories of Manly Wade Wellman. One Silver John novel, The Old Gods Waken, had the Man In The Oak, a kind of undead tree-spirit, as its main villain, along with a grove of literally bloodthirsty thorn vines. He also did several short stories that featured evil trees.
  • In Teresa Frohock's Miserere: An Autumn Tale, the Rosa.
  • Galaxy of Fear: Spore has an encounter with the vesuvague, a tree with mobile strangling vines.
  • In the fourth book of The Dresden Files, one of the villains sends a plant monster after Harry. He calls it a chlorofiend, because saying 'plant monster' sounds silly, but no one understands what he's talking about so he has to revert to calling it a plant monster. Murphy kills it with a chainsaw.
  • Lensman: Worsel the Velantian almost comes a-cropper from this fate in Galactic Patrol. Attacked by four tentacular beings and overwhelmed, he finds his telepathic command ability is useless. Lensman Kim Kinnison has exactly the same problem trying to save him, and resort is made to sharp objects. Authorial exposition clarifies the issue for the reader.
  • In The Underland Chronicles, lots of the plants in the Jungle are carnivorous.
  • In Poul Anderson's The Star Fox, humans trekking across an alien world find themselves in a forest that attacks. They hypothesize various evolutionary possibilities — though one admits they are trying to look for a naturalistic explanation.
  • In one of Mercedes Lackey's Tarma & Kethry stories, part of the Valdemar setting, when Tarma thinks about making a fire, a sapling pulls itself up by the roots and runs away. Tarma shudders to think what its great-grandmother might do to someone wanting to build a fire.
  • Likely the most powerful example of this trope, in Sean Williams's series The Books of the Cataclysm, the Big Bad is Yod, a tree-like god or Eldritch Abomination that inspired the myth of Yggdrasil the World Tree. Yod has almost completely consumed the universe and it is only in one single time-stream that Yod hasn't totally devoured the cosmos.
  • In The Iron Teeth web serial there are creatures known as mimics. Mimics disguise themselves as trees and prey on creatures that get too close. They're not actually moving trees though, they're somewhat like giant stick bugs or crabs that have symbiotic plants and leaves growing from them.
  • One of the alien species encountered in Eden Green is a parasitic vine that infests trees and attacks those who come near. The main character 'affectionately' nicknames them 'Whomping Willows'.
  • In The Traitor Son Cycle, one of the biggest villains, Thorn, has turned himself into an ambulatory tree that towers over even the tallest Wild creatures, has oodles of magic power and is hell-bent on destroying human civillization.
  • In Great North Road by Peter F. Hamilton, the bullwhip trees on the planet St. Libra have long, coiled up branches that can whip out and hit a person. The whole planet is also conscious and not too happy about humans being on it.
  • Solar Pons: "The Adventure of the Grice-Paterson Curse" features a creeper plant that is able to reach its vines through a window to strangle its victims.
  • In The Green Knowe Chronicles, the ancient tree Green Noah that stands on the grounds of Green Knowe was afflicted by a gypsy curse which caused it to be possessed by a demon, allowing it to sometimes prowl around at night in search of victims (including, supposedly, the witch who cursed it). It almost gets its leafy limbs on protagonist Tolly until Divine Intervention causes it to be struck by a bolt of lightning and destroyed.
  • In Sarah Douglas's The Wayfarer Redemption, to eradicate the monstrocities and madmen unleashed by the Timekeeper Demons, the heroes use female Banes who became living trees to smash them while resurrected Icarii archers pepper them from the air with an unlimited supply of arrows.
  • In the second Time Out Of Time book, "The Telling Stone", during the battle at the Travelers' Market against Balor and his forces, the trees rise up from their resting places and come to the marketeers' aid.
  • Short and Shivery: The titular character in "Crooker Waits" turns out to be a sapient yew tree, which attacks the hero as he tries to make a midnight trip to his sick mother. Luckily for the hero, the plants he receives from three old women fend it off and ultimately kill it before it can finish him off.
  • The Plant That Ate Dirty Socks: While not a tree, Jason's plant (grown from one of the titular plant's seeds) is pretty hostile at times, to the point where it actually attacks people who get within range. Fortunately, Norman is able to tame it.
  • In The Edge Chronicles, Bloodoak trees catch passerbys with their vines and drop them into the mouth they have on top.
  • In Tinker, the carnivorous and mobile black willow trees are one of the apex predators of the Elfhome ecosystem.

    Live-Action TV 
  • In one episode of The Adventures of Sinbad, the heroes faced deadly trees which had the ability to walk.
  • An episode of Angel had a demon tree that would capture people with its vines and drain their body fluids.
  • The MC Bat Commander and Eaglebones Falconhawk find themselves trying to tie a ribbon to the top branch of a tree in The Aquabats! Super Show! episode "Uberchaun!". The tree comes to life and attacks them; eventually Eaglebones summons The Dude to tie the ribbon, and the tree becomes dormant.
  • Doctor Who:
  • The Haven episode "Roots" had trees that extend their roots like tentacles to tear people apart. They were animated by The Power of Hate between the feuding Keegan and Novelli families, and revert to normal when they make peace.
  • In Legends of the Hidden Temple (a Nickelodeon Game Show), the "Dark Forest" room had trees with face-like holes and arm-like branches. Contestants had to reach inside them to find the key to the next room, but were warned that they might be possessed by the spirit of a Temple Guard. Needless to say, "might" meant pretty much always, and it was blind luck whether or not the contestant picked the right tree to avoid being grabbed.
  • The Hitcher has an "evil tree" minion in 1 episode of The Mighty Boosh.
  • An early Saturday Night Live skit, "The Killer Christmas Trees", played like a horror movie - opens with Garrett Morris singing an a capella "O Tannembaum" while a fir tree skulks up behind him, and impales him through the chest.
  • A mild version appears in an episode of Star Trek: Voyager where it's played for laughs. Captain Janeway buys an alien plant without realising it's prehensile. "I went to water it and it GRABBED me!" — causing fans to quip that the plant was getting more action than Chakotay ever did.
  • The X-Files: "Schizogeny" appeared to involve trees killing people. However, this being The X-Files, a fair amount of what was going on and why is left up to the viewer.

  • Forest King by 3 Inches of Blood.
  • The Maples screaming "OPPRESSION!" at the uncaring Oaks, in the Rush song The Trees.
  • The cover of Iron Maiden's Fear of the Dark has Eddie as a tree monster.
  • Brentalfloss' "Final Fantasy With Lyrics" includes the following line, set to an image of an oak with Brent's face:
    Draw your sword and stick it in trees that have human features!

    Myths & Religion 
  • English folklore has the rhyme "Elm do brood, and oak do hate, but the willow walks when you travel late". Oak coppices were thought to be full of Oakmen, vengeful fairies who fed travellers poisonous fungi. Willows were thought to uproot themselves after dark, to walk behind travellers and mutter.
  • In Welsh mythology there's the story of Cad Goddeu (The Battle of the Trees), in which the enchanter Gwydion animated the trees of the forest to serve as his army. There's a poem about it in The Book of Taliesin.
  • In Japanese folklore, the jubokko is a youkai created when a tree grows on the site of a battlefield where massive casualties were suffered. Having gained sentience and a taste for human blood from the blood-soaked soil, the jubokko grabs anyone who gets too close and drains them of their blood, leaving the body to be pecked at by scavenging birds.

  • The Raven of The Adventure Zone: Balance uses the Gaia Sash to create aggressive vines, poisonous thorns, and, at one point, a Treant called Trent.

    Print Media 
  • In 1874, New York World reporter Edmund Spencer released an article about an allegedly-carnivorous tree from Madagascar, to which a native tribe sacrificed women in exchange for a narcotic nectar. Although solidly debunked some years later, subsequent periodicals and authors kept right on repeating accounts of the "Man-Eating Tree of Madagascar" until at least 1932, long after it was verified that both the tree and the tribe had never existed: Spencer'd made up the story by exaggerating the characteristics of the familiar Venus fly trap.

    Pro Wrestling 
  • Marutambo, the one branched tree of Kaiju Big Battel. He's more so a man who was horribly mutated into a nearly indestructible bark monster.

    Tabletop Games 
  • Dungeons & Dragons:
    • The adventure "The Wandering Trees" in Dragon magazine #57.
    • Monsters: treants, quickwoods, hangman trees, etc. These can get really creepy, like the Death's Head Tree, which resembles a willow that sprouts screaming, biting human heads as fruit (each of which is the head of one of its victims) and the Seedroach, whose "seeds" are animated cockroach-like constructs of woods that sting living beings and turn them into new Seedroach trees.
    • Another enemy, the Wolf-In-Sheep's-Clothing, only looks like a tree stump with a rabbit sitting on it... but if you get too close to it, it will grab you and try to eat you.
    • Something in the soil of Ravenloft turns all plant-creatures that grow there into homicidal killers, even if they'd otherwise be good guys. There are vampiric undead treants there.
    • Eberron is a setting where all the NPCs are of relatively low-level, so that the player characters are the ones who kick ass and take names. The most powerful NPC in the setting? A level 20 druid who's an awakened tree.
    • Someone once jokingly mentioned a Treant Ninja. But think about that for a moment. In its home turf, you're looking at a huge, deadly, practically invisible creature that can kill you one by one without anyone knowing what it is. Basically, The Blair Witch Project.
    • The deadliest example of this trope in D&D is probably the odic, a tree-possessing evil spirit so powerful that you can lose levels just by getting close to it.
    • From Dragon #123: a Coconut Ent. So, <Bonk!> the movement rate isn't a big issue anymore.
    • "Heroes of the Feywild" features the Hamadryad as a player character race. They're basically standard Dryads that are (for one reason or another) no longer bound to a specific tree, but still have the "plant person" look. An earlier book also released the "Wildkin", although that's more along the lines of "when shrub-elves attack".
    • Ironthorns are trees about the size of an apple tree, with leafless branches resembling nothing so much as a tangle of vines or tentacles covered with poisonous thorns. When a passing creature gets too close, the ironthorn snatches it with its branches and impales it on its thorns to feed off of the body.
  • Warhammer: The Wood Elves of Athel Loren have access to a number of such creatures in their armies:
    • Dryads disguise themselves as beautiful human or elven women until an enemy comes close, then shift back to their true forms as terrifying tree monsters and tear them limb from limb.
    • Tree-kin are created from the souls of dead Elves fashioning hulking bodies from dead wood and gnarled beaches, and march alongside their living kin in times of war.
    • Treemen, which are pretty much the same thing as Tolkien's ents, are created when powerful spirits merge permanently with living trees and are among the mightiest creatures in Athel Loren, living only to protect it and to bring terrible vengeance on anyone who would threaten or despoil their woods.
  • Warhammer: Age of Sigmar: The Treemen from above are now clan-leaders of an entire faction of tree-folk called the Sylvaneth. Aside from the Treelords, Tree Revenants, Dryads, and other tree-people, they also have about six different ways to spawn forests on the battlefield, which react violently to non-Sylvaneth interlopers and even more violently to magic cast near them. Oh, and they can be moved around by Sylvaneth magic, taking anyone within the forest along for the ride.
  • Warhammer 40,000:
    • The Spiker (seed turns you into another one) and Brainleaf (spikes you and you turn into a zombie) are both horrifying, but non-sentient. This hasn't stopped at least one account in the lore of the Imperium seeding an Ork world with the things to keep the planet unusable.
    • Feculent Gnarlmaws are hideous, twisted trees with fang-lined mouths running vertically down their short, stocky trunks and only a few gnarled, leafless branches hung with bronze bells and spouting clusters of tube-like tentacles. They mostly grow in Nurgle's garden of plagues, but germinate in the physical world when an area becomes particularly corrupted by daemonic pollution.
    • There are several other deadly plants in the 40K galaxy, some typical carnivorous plants, others more unusual. The official website has a nice article about them, complete with rules for using them in games.
  • Dragon Dice has the Treefolk, an entire race/army of sentient, mobile trees and their Naiad and Dryad allies, animated by Mother Nature as a last ditch effort against the forces of Death.
  • Mage Knight miniatures has the Tanglewood Spirit, and later, the Oak Warrior and Oak Mage. If moving trees are scary, how about a tree that casts spells?
  • "Century Trees" in Deadlands: Lost Colony inhabit the Toxic Jungle on the planet Banshee. They're mobile, they're named for their height (over 100 feet tall!) instead of their age, and they don't like you.
  • Poisonwood trees in Talislanta. They don't attack, but don't touch these things if you value your life. Don't get shot with a poisonwood arrow either.
  • The Star Wars tabletop RPG introduces Darth Rivan, Sith Lord and sentient plant.
  • Legend of the Five Rings has the Morei no Oni, a tree-shaped demon. By themselves, they aren't that tough: they can't move, and their attacks are neither fast, nor accurate, nor particularly damaging. However, they drop seeds that look like grains of rice, and if anyone accidentally eats one, the seed will eat that person from the inside out and eventually sprout as a new Morei no Oni from the corpse. And supposedly the forces of evil like to slip these seeds into bags of otherwise good rice. Enjoy your dinner.
  • Gamma World features numerous post-apocalyptic varieties, both as attacking monsters, and a racial option during character generation.
  • GURPS Fantasy Bestiary: Fairy thorn trees shoot volleys of envenomed thorns at anyone who walks by them, inflicting their targets with a variety of psychological malaises such as selfish egotism or intense jealousy of others. It's not know why they go through the trouble of doing this, although some speculate that they remember when trees covered the land before humans came along with axes and fire and resent humanity's advance.



    Video Games 
  • Gryphon Knight Epic: One of the enemies you face is a giant mobile tree. One of its attacks is to extend its arms out and cover it with spikes.
  • Pokémon gives us Exeggutor, Shiftry, Tropius, Snover, Abomasnow, and Trevenant. When you have an entire type of Mon devoted to plants there's bound to be a lot of these. Interestingly enough, Sudowoodo looks like this, but is actually a tree mimic made of rock. The weirdest yet may be the Ultra Beast Xurkitree, which acts very similarly to (and slightly resembles) a walking tree, yet is a living collection of electrical wires and zipties.
  • The Carnivorous Trees in Phantasy Star IV, which are also a Puzzle Boss.
  • The Living Forest in Mortal Kombat had talking trees that were (falsely) rumored to be able to eat the players as a special fatality. Midway took care of this oversight in their later MK games.
  • One of the bosses of House of the Dead 3, the Sun, is a large carnivorous tree with Combat Tentacles and human faces adorned on its body.
  • EarthBound:
    • The infamous Territorial Oaks, and their Palette Swap Hostile Elder Oaks. These, by the way, explode when you kill them. At the level you first encounter them, you usually survive only if you can press buttons fast enough to exit battle before your health meter runs out. Because of this, it's best to only fight them when they come in singles and, if other monsters are with it, to take it down last so that the damage doesn't count down for long before victory is declared, stopping the drain. And to make matters worse, they carry 1/128 items as well. Hope you enjoy pain, collectors!
    • There's also the Woodoh of the prequel, Mother 1, and the Tree and Tender Loving Tree of the sequel, Mother 3. Most of them explode as well.
  • Brigandine includes a man who's been sorta absorbed into the roots of a tree.
  • Whispy Woods from Kirby. Kirby Super Star introduces Twin Woods, which is basically two Whispys at once, and Kirby 64 adds mobile saplings named Whispy Woods Jr. Kirby Mass Attack introduces many relatives of Whispy Woods as enemies, namely Little Woods, Wicky Woods, Tower Woods, Floaty Woods, Wobbly Woods, and... Stumpee. Kirby: Triple Deluxe has Flowery Woods, a flower transformed by Taranza into a tree. Kirby and the Rainbow Curse has Whispy Woods take on a claymation form. Kirby: Planet Robobot has Clanky Woods, a roboticized Whispy Woods. Kirby Star Allies has Yggy Woods, an elderly cherry tree resembling Whispy Woods, and Parallel Woods, a counterpart of Whispy Woods from Another Dimension.
  • The Devouring Earth in City of Heroes have animated trees (Bladegrass, Razorvine, Deathblossom) and big animated mushrooms (Fungoids, Deathcaps) among their ranks.
  • King's Quest:
    • King's Quest IV: The Perils of Rosella had several screens' worth of the Type-1 variant, which would grab and kill you if you got too close to them.
    • Mask of Eternity also has the Mandragor Trees, monsters found in the swamp that turn to regular trees upon beating them. They're immobile, but if you come too close, they'll attack you with their roots. And they can't be hurt by ranged weapons, which they will laugh off; the laughter is horrific.
  • Suikoden IV had a giant killer tree for a final boss.
  • La Pucelle had an overpowered demon tree for a boss. You can choose to go the easy way by going to a separate room to weaken it, or you can take the hard way and beat it down as it is. The hard way earns you a neat equipment at the end of the chapter.
  • The Elder Scrolls:
    • The series has Spriggans, which are particularly tree-like Plant People. They have a Gaia's Vengeance tilt and are known as "Nature's Guardians." Depending on the game, they either must be killed three times before they'll stay dead or they come with a rapid Healing Factor that kicks in when they are near death. One of their favored methods of attack is to blend in with surrounding trees and plants, then ambush their unaware targets. They appear in Daggerfall, Morrowind's Bloodmoon expansion, Oblivion, Skyrim, and Online.
    • The Hist, a race of ancient, sentient, and possibly omniscient trees native to the Black Marsh subvert this trope. Though sentient and capable of communicating with each other and the Argonians, who worship them, they are otherwise entirely tree-like - stationary and defenseless on their own. However, they can incite the Argonians to attack on their behalf.
  • Bloodline Champions has a bloodline called the Thorn, which are more or less monster trees.
  • Age of Mythology had a god power that animated trees well-suited to tearing buildings up.
  • Shin Megami Tensei: Strange Journey has Yggdrasil as having a Game-Breaker ability to manipulate time. Unfortunately, the people he stole it from are time travellers, and they eventually get it back, setting a Stable Time Loop in motion in which he always loses with the help of a Future Badass. Namely, you.
  • One of the first major enemies in Golden Sun is King Tret, who normally isn't that hostile. Unfortunately, a Psynergy crystal impacted his trunk, giving him a vicious Split Personality that turns everyone within range into trees. Once that persona is under control (i.e. the heroes beat the sap out of it in a Boss Battle) and his injuries are healed, Tret gets his old self back.
  • A common enemy, the Killer Tree, in Dragon Quest.
  • WarCraft:
    • Treants and the larger Ancients in WarCraft III are guardians of nature and common allies of the Night Elves (the latter type serve as buildings and can be uprooted to fight or relocate the base).
    • The basic treants can be summoned from trees by the Keeper of the Grove hero. Neutral treants come in several varieties (all mobile, one poisonous, and one doubly prehensile as it can cause roots to erupt from the ground to immobilize and damage an enemy), all of them evil.
    • In World of Warcraft, Balance druids can summon treants to fight for them, while Restoration Druids can become treants without any offensive capabilities but improved healing.
    • Treants are generic fighting machines in Warcraft, but in Defense of the Ancients: All-Stars there is a Treant Protector which is a hero with one of the best strength ratings in the game — a tree that not only attacks, but causes the woods around him to attack also.
  • In League of Legends, Maokai the Twisted Treant is a tree brought to life by magic. His animation was not of his will, however, and more or less wants to find a way to return to his roots, so to say. There's also Ivern, the Green Father, though he's very unlikely to attack anyone if he doesn't have a very good reason; most of the danger he poses comes from his friends, which include his teammates and a giant stone golem called Daisy.
  • Final Fantasy Mystic Quest:
    • Early on, a boss is disguised as a tree.
    • Later on in the game is the King of the Forest, a giant tree that can walk and talk. The King is good, in fact you must go inside him and destroy the monsters poisoning him.
    • Not to mention the various tree-shaped regular enemies. The first, Mad Plant, is fond of putting the heroes into full-nelson holds. Yes, really.
  • The enchanted dead trees near Draynor Manor in RuneScape, and also in the Haunted Woods area; both places are controlled (or were controlled, in the case of the former) by Vampyres. This may or may not be a coincidence.
  • The Holy Sapling boss of Magical Starsign is a gigantic tree monster that covers a good portion of both DS screens. Its main attacks are inhaling one party member (it has a face), gnawing on him or her, then spitting them out; and growing buds that bloom into flowers, then launching the petals at you. When you defeat it, it becomes a passive Man-Eating Flower.
  • Final Fantasy:
    • About halfway through the game, Final Fantasy V's Exdeath, a powerful wizard who is the epitome of the Evil Overlord archetype, is revealed to be an evil tree. (More specifically, a tree that had had so many evil spirits sealed inside it that it became sentient—and evil—itself.)
    • Also, many of the games have minor enemies that are trees or tree-shaped: the Treants from Final Fantasy IV, or the Dryad species from Final Fantasy Tactics.
    • There is also Exodus (who is based off of Exdeath) in Final Fantasy XII and Final Fantasy Tactics Advance, who appears as a summon monster.
    • Final Fantasy IX has the living avatar of the Iifa Tree, Soulcage, as a particularly nasty boss. Those who try to attempt the logically obvious "Kill It with Fire" will be unpleasantly surprised.
    • Not quite this, but Final Fantasy X has the Guado race, who are humanoid, but are molded in a way that makes them resemble trees (long arms, bushy hair, wide shoulders and thin hips, etc.). They retroactively resemble Elder Scrolls Spriggans. They also live among giant trees.
    • Malboros, recurring monsters in several Final Fantasy iterations, resemble giant trees with tentacles and huge toothy mouths. Frequently they rank among the toughest non-boss opponents in the game.
    • Sephirot the Fiend in Final Fantasy XIV has the backstory of being the world's very first sacred tree. Five thousand years ago, a tree-like race that worshiped the tree prayed for salvation from the invading Allagan Empire, which caused the tree to become a six armed demon able to wield the power of nature and grow to colossal heights.
  • Touhou has the Saigyou Ayakashi from Perfect Cherry Blossom, a demonic cherry tree. We never do actually get to see it in action because it is magically sealed by the body of its final boss, Yuyuko Saigyouji, and you spend the game preventing this seal from breaking; however, it is known to have killed many, many humans in the past. It's saying something about Touhou when a tree is one of the few truly evil beings in the entire series.
  • Taken to ridiculous heights in the side-scrolling mecha game, Xardion. The first area of the last level involves bomb lobbing flying/hopping trees trying to kill you once you land as you make your way to the planet's core. This is obviously the beginning of the Mind Screw section.
  • Aggressive plants are a fairly common enemy in Guild Wars, ranging from small but annoying seed-things to full-blown mobile trees, often with spellcasting ability.
  • Corrupted trees in Ōkami pelt you with rotten fruit.
  • In Quest for Glory I, there is a Dryad who is very protective of the forest, and if you kill or threaten the local wildlife, she'll transform you into one of the local wildlife.
  • There's a miniboss in Wario World aptly called Tree Freak who is exactly one of these dangerous, semi sentient trees and is fought three times in one of the levels.
  • In a side story of Tsukihime, it is revealed that one of the 27 Dead Apostle Ancestors is a forest that absorbed the blood of an Ancestor that Arcueid killed. It was named after the former Ancestor and became known as the "Forest of Einnashe". The entire forest gained sentience and was known to wander around, swallowing entire towns in its wake and tempting people to enter with rumors of an immortality-giving fruit tree. Being an entire forest, not much could be done about it for all of 800 years. That is, until Satsujinki came along...problem solved.
  • In Illbleed, one of the boss monsters is a demonic tree that's taken over a lumber mill. Amusingly enough, when you first get to the boss it's undergoing repairs. Apparently, even in an Amusement Park of Doom attractions sometimes break down.
  • The Legend of Zelda:
    • The Legend of Zelda: Ocarina of Time has you enter the Great Deku Tree as the first dungeon, who is the god of the Kokiri and a talking tree. He doesn't attack you, though the many Deku Babas and Scrubs will, presumably as a result of Ganondorf's death curse on him.
    • In The Legend of Zelda: A Link to the Past, some of the trees in the Dark World would spit bombs at you if you bumped into them... and then talk to you as if nothing happened afterwards.
  • Wizardry VII: Crusaders of the Dark Savant had hostile trees as one of its less common enemy types, though they were largely unremarkable save for the spell-casting Halloweeches. One optional sequence in the game involves the party being assaulted by seemingly half the forest in several waves of attackers.
  • Kingdom of Loathing: During October 2009, thanks to the weird in-game calendar, Arrrbor Day (an in-game holiday where pirates plant trees, hence the multiple r's) was just a few days away from the real-world Halloween. Thus "Arborween" was born: the Arrrboretum became the Shivering Timbers, with Halloween-themed trees (pumpkin trees, toilet-papered trees, the Underworld Tree, etc).
  • Sort of happens in Overlord; the Elven hero Oberon, consumed by Sloth, has merged with a giant tree, which animates in order to attack the... er... "hero".
  • The trees that inhabit Xen in the last levels of Half-Life, which attack anything that moves near it and, thanks to Good Bad Bugs, can be used to kill one of the ridiculously tough Gargantuas. It is speculated that the massive, impossible-to-kill Tentacles that are encountered in several portions of the game is its mature form.
  • The first Ape Escape has... er... vehicular trees in the forested levels that certain monkeys operate, initiating a small boss fight. The Trees are rooted to the spot, and could be avoided by staying outside the range of its flailing branches.
  • Dragon Age has sylvans, which are trees possessed by demons and spirits. They tend to lie in wait until someone passes by them, at which point they move to attack. The vast majority are mad, violent creatures that can cause sharp branches to erupt through the ground and impale smaller beings. A rare few seem benevolent and don't mean any harm to others.
  • Age of Wonders: Shadow Magic Elves got a Treeman. "Concealment" there means that if this wall-crushing behemoth stands in a forest, foes will not see it until it's one step away.
  • Mega Man 2: While Wood Man is a robot, he's certainly walking-tree-themed.
  • The fourth stage of Gun Nac was the Wood stage, so one of these naturally appeared as the boss.
  • Battle for Wesnoth brings us Woses, similar to Tolkien's Ents in personality, but more like Huorns in appearance. They're easy to hit, but pretty tough (if vulnerable to fire), can hide in forests to potentially ambush enemy units that stray close, and they regenerate.
  • Hashi of The Black Heart, especially when using his ultimate ability.
  • Gaia in Grandia evolves into a bug/tree hybrid in the end.
  • Ancient Domains of Mystery has an entire level crammed with extremely tough walking trees. It's possible to get through the level slowly by waiting for them to move at random and fighting the few hostile ones... or by just smashing your way through it with brute force. Using fire attacks (which they are weak to) will make ALL the trees attack you.
  • Patapon 3 has Treants, who normally don't move, but, if you try to use fire weapons on it, it will wake up and start flinging fireballs at your army. And if it happens to be a rainy day, they will gain HUGE amounts of health back.
  • Throughout the Thief series, the Pagans often uses tree-like creatures to guard various locations.
  • Super Mario Bros.:
  • The boss of the first world of Athena.
  • Ryuji, the penultimate boss of Ar Tonelico 2.
  • In Crystal Castles, the enemies included walking trees.
  • The Lord of the Rings Online has plenty of trees that will gladly uproot themselves and whale on you if you piss them off. All of them are Signature-level or worse.
  • The Battle for Middle-Earth: The Fangorn and Isengard missions of the first game (both campaign). Ents (including the Treebeard hero unit) can also be trained as Rohan units in the first game, and as Elven units in the second.
  • LEGO The Lord of the Rings uses the Ents as well. You play as Treebeard (well, technically, Merry or Pippin sitting on Treebeard) in two levels, one where they first find him and head towards Isengard, and another where the Ents smash Saruman's machinery.
  • In Dark Souls, Darkroot Garden has plenty of Demonic Foliage, and they sometimes like to hide in the ground to ambush you. There are also the sort-of mobile (they can rotate) Possessed Trees, but they're just their to be cut down to open up paths.
  • In Science Girls!, most of the enemies look like plants, and there's a Treeman boss. Subverted in that they're not biologically plants.
  • In Minecraft, the Creepers are mottled green, have multiple legs but no arms, and according to Word Of God their hide feels like leaves. This makes them strongly resemble mobile, explosive plants. Notch has said that, were they real, their texture would be "crunchy, like dried leaves", basically meaning they're supposed to be concussive walking topiaries.
  • Legend of Mana: At least one enemy is in the form of a walking tree, and the last boss is the Super-Powered Evil Side of the Mana Goddess, the spirit of the Mana Tree.
  • Subverted in Diablo III: The Wood Wraiths are actually fully mobile beasts who have evolved to look like trees and foliage in order to ambush prey and, in fact, have nothing to do with plants.
  • Amagon has a Devil Tree as the boss of Zone 2.
  • There are a couple of different (but similar looking trees) in Shining the Holy Ark. You're walking long and suddenly the ground rumbles and a tree will grow in front of your face in the matter of seconds. It'll then proceed to attack you...for some reason.
  • Little Nemo: The Dream Master has Stumper, a tree stump that is trying to kill you. Oddly, it turns up in several underground areas.
  • Command & Conquer: Tiberian Dawn has Blossom Trees. While harmless on their own, they emit gasses that create Tiberium crystals, which are incredibly toxic to all forms of life on the planet.
  • Whroon, the Forest boss in Death Smiles.
  • Silent Assault has a fire-breathing tree as its penultimate boss.
  • In Hocus Pocus, the bosses at the end of Episode 2. They are mobile and you can easily get cornered if you're not careful. And touching them means instant death.
  • An old arcade game called Crystal Castles had enemies called "Nasty Trees" (which got more ornery as you progressed from level to level).
  • An enemy in ActRaiser's first level.
  • Realm of the Mad God has the Ent Ancient and Ent God.
  • Impossamole has Bark, the boss of the Amazon Jungle.
  • Atelier Meruru: The Apprentice of Arland has the Spirit Guardian of the Forest of Ent.
  • The Dendroid Guards and Soldiers of Heroes of Might and Magic. Slow, but strong, and their attacks leave their victims rooted in place
  • Don't Starve:
    • If you cut down too many evergreen trees, there's a chance that a nearby tree will become a ferocious Treeguard, monster shaped like a humanoid tree that will then try to kill you. Fortunately, planting new trees may cause a Treeguard to stop attacking you. Similarly, the Shipwrecked DLC includes Palm Treeguards, which spawn when you cut down palm trees and will try to kill you until you pacify them by planting coconuts to make more palm trees.
    • There's a similar mechanic with the Birchnut Trees. When you cut them down, there's a chance a nearby birchnut will "awaken" and become a Poison Birchnut Tree, an otherwise normal deciduous tree with purple leaves, a giant maw in their canopy, and a single eye perched on thin branches at their top. Unlike Treeguards, Poison Birchnuts are immobile, and attack by sending out waves of Birchnutters (small, mobile and aggressive nut-like creatures) and by attacking through the ground with their flexible roots. Like Treeguards, you can placate by planting Birchnuts to make new saplings, or by waiting a day or so until they calm down and turn back into normal Birchnut Trees.
  • These come in multiple flavors in Meteos: The civilization on Planet Wuud, which consists of trees, and the civilization on Planet Florias, who are flowers. The inhabitants of Anasaze are likely cacti. Of course, since these are all different planets, they overlap with Plant Aliens too.
  • Quest 64 and Quest: Brian's Journey both have a Treant. The former has a demonic looking tree, with a simple attack involving throwing around blades of wind. The latter looks more like a lively tree with lots of leaves, and attacks with some deadly rocks.
  • Terraria has Everscream, Mourning Wood, Splinterlings, Plantera and various jungle/fungus related enemies.
  • Dante's Inferno has an area called the Wood of the Suicides. In it, a number of trees drop fruit that produce an area attack when they hit the ground, the effect of which on Dante is to cause him to try to kill himself unless the player mashes a button enough. Its effect on enemies is to stun and damage them. There are often points to attack to make them stop, though, and after you find out that one is Dante's mother, Dante gained the ability to use the fruit himself.
  • In the Civilization IV mod Fall from Heaven, the Ljosalfar have "March of the Trees" as their World Spell (a powerful single-use ability). All forest tiles within the faction's borders (those unoccupied by enemy units) are transformed into Treants (10 strength) for 5 turns. After that time, they turn back into forests wherever they are located. Only really useful if the faction is getting invaded, and you lack defensive units.
  • Fantasy Life has enemies that are basically walking trees in Elderwood and Tortuga Archipelgo.
  • Ryzom has an entire species of creature devoted to this trope, called "Intelligent Plants". Attack or otherwise mess with one, and they won't hesitate to kill you with their magic (as the Matis learned the hard way when they experimented on one such plant, the Slaveni).
  • In Kult: Heretic Kingdoms, tree-based enemies can be fought in the forest. Unlike a lot of examples, these are more tree-stumps than full trees.
  • In Gems of War, one of the troops associated with the Forest of Thorns is the Treant, a walking, talking tree. One of them is the main antagonist of the Forest of Thorns quest line, having been corrupted.
  • The first stage boss in the Genesis version of Castle of Illusion is a living log that jumps out of the tree it's resting in and rolls towards you. The Master System version just has a tree as the first boss. The remake adds an explanation of sorts; the narrator refers to this boss as the "Grumpy Old Oak"; so apparently it was attacking Mickey either just because it was a grouch, or because Mickey woke it up or something.
  • In Dark Souls III, the Curse-Rotted Greatwood is a huge tree that the locals once used as a garbage disposal for curses. The curses gave the tree unnatural life. The pale arm that bursts out of the tree midway through the fight implies that something is incubating in it.
  • In early pre-release versions of Dwarf Fortress, treants were planned to be units available to elves for warfare, but were eventually relegated to being fictional in-universe (showing up in artwork), and later removed entirely. The base game still has grimelings, being described as something like Swamp Thing (though still a flesh-and-blood creature in the actual code). Treants are occasionally seen in Game Mods though, which tends to go about as well as expected given magma is the universal dwarven problem-solver. Unless the modder plans for that and makes them able to survive being immolated.
  • Grover from SMITE and Paladins is a treant who is the mount of the god Sylvanus in the former game and an axe-throwing support champion in the latter game.
  • While many tree based plants exist in the Plants vs. Zombies series, the shooter games play with this trope more.
    • In Garden Warfare 2, two boss plants Big Stump and Giga Torchwood. The former has a club as a weapon and the latter a Gatling flame gun attached to his arm. Giga Torchwood is able to set things on fire while Big Stump just beats up zombies up close. Torchwood was later condensed into a playable character class filling the role as The Juggernaut.
    • The zombie campaign plot in Battle For Neighborville revolves around an invasive plant species (Dreadwood) that started overgrowing Z-Tech factory and destroying it in the process. It makes active attempt to fight the player off.
      • In the same game, the Acorn class has the ability to transform into an Oak tree. Oak is based off the Torchwood class in the last game.Endless Legend's Wild Walkers can make the Tenei Walker units, which are basically giant ent-like tree creatures that serve well as tough front-line troops. Like all other Wild Walker units, Tenei Walkers get even stronger when fighting in forests.
  • The first boss of Kameo: Elements of Power is one of these. He's named as Old Malwood.
  • Magamandra, the Ostracized Vile Tree from Ys VIII: Lacrimosa of Dana.
  • Cursed Stumps in The Legend Of Pirates Online are rare but powerful enemies that can only be found in the deepest forests or the most deserted islands of the Caribbean.

    Web Comics 
  • The Order of the Stick:
    • Durkon and the rest of the dwarves have a racial fear of trees. (Why else would Thor's lightning strike them all the time?) His fear is justified when he meets an evil druid with a small army of trees. His whole species hates trees to the point where they launch WARS against them. It's considered a major crisis when a tree root manages to break through the walls of the underground homes.
      Durkon: Just one tree has Colossal size, natural armor, damage reduction, hundreds o' hit points, and enough limbs ta make a dozen or more attacks per round.
    • Thor himself, on the other hand, finds this phobia ridiculous; he kept hitting trees with lightning because that's what lightning does, and the dwarves came to believe there had to be a good reason Thor was doing that. That being said, he's not shy about using the fact that dwarves war with trees to loophole around the "dies with honor" restriction of the dwarven afterlife.
      Hel: Infection! She's mine!
      Thor: From a splinter she got while fighting an elm!
      Hel: Trees are inanimate plants, you buffoon!
      Thor: Bravery knows no limits!

  • Doug: Roger scares Doug with a story of punching trees in the forest.
  • One DuckTales (1987) episode seems to turn the Macbeth subversion on its head. When Scrooge goes to an island to retrieve a lost play of the Shakespeare-analog of the world, he's attacked by animated trees, among other dangers inspired by Shakespeare plays. They're actors in tree suits, of course, pledged with defending the lost play, which is actually quite horrible.
  • Family Guy. Stay away from the Candy Tree.
    Candy Tree: He's right to caution you. I feed on children.
  • In the made-for-TV Felix the Cat cartoon "The Professor's Instant Changer", Professor disguises himself as a tree using his Instant Changer device. Felix gets annoyed at the tree disguise and unwittingly whacks professor with a wooden stake, which allows Felix to reclaim his Magic Bag—but also prompts Professor (still disguised as a tree) to chase after him. Felix tries to counter him by turning his Bag into a buzzsaw, but Professor counteracts this by turning the tree disguise into a boulder, which quickly wears out the buzzsaw. Felix counters this in turn by lighting dynamite by the "boulder", with the explosion hurling Professor back to his lab.
  • In The Grim Adventures of Billy & Mandy, the Taking Tree in Billy's yard. It steals items and will only give them back if they give it something better in return. It takes Billy and requires an extremely rare baseball card in return.

  • The Redwoods from Inhumanoids are sentient trees who give assistance to the heroes every so often. Meanwhile, one of the primary antagonists is Tendril, a kaiju-sized shambling mess of vines that can grow clones of himself.
  • One of these shows up on Jimmy Two-Shoes, which Jimmy nearly... relieves himself on during a Potty Emergency.
  • One villain from Krypto the Superdog brings every tree in the city to life, hoping they will follow this trope. The scheme falls apart for two reasons: one) the trees actually appreciate the humans that take care of them, and 2) they are trees. They don't like moving around much and prefer being rooted to the ground.
  • The Laughing Tree from Little Bear was a scary tree that grabbed people and wouldn't let them go unless they made him laugh.

  • Robot Chicken:
  • Aku, the main villain of Samurai Jack, is not a tree per se, so much as he is an Eldritch Abomination that came FROM a cursed tree. In his most common form, his body makes wooden creaking and crackling noises whenever he moves, and his body language in general tends to be very stiff. The Scotsman even calls Aku a "tree-ogre" in Season 5 just before Aku disintegrates him.
  • In the Sealab 2021 episode "Isla de Chupacabra", one of these eats Stormy at the end of the episode. Considering the island also has the Chupacabras, the talking venomous hanging tree cobras, and presumably other horrors, it's an excellent example of a Death Island.
  • The Simpsons mentions that trees cannot defend themselves, except for the Mexican Fighting Tree, of course.
  • In one episode of The Smurfs, Gargamel gets what he thinks is a good idea, using magic to bring the Great Oak to life in order to ask it where the Smurf Village is. Then he gets a bad idea, making it angry. Then he gets an even worse idea, doing the same thing to every other tree in the forest. Suffice to say, the chaos that ensues requires Mother Nature herself to fix.

    Real Life 
  • The manchineel: word of caution — try not to shelter from rain under this lovely looking windbreak of a tree. Blisters are the start of your problems. These were once used as a form of slow execution method: tie offender to one's trunk and watch them slowly die painfully of the various toxins. The conquistadore Juan Ponce de Leon was killed by a dart covered in machineel poison; humans have always had an unfortunate but natural tendency to weaponize natural toxins that can be harvested.
  • The Sandbox Tree. It is a poisonous tree. Its bark is covered with spikes. It grows up to 100 feet. Its sap is highly poisonous and corrosive. Its fruits are rather large and explode when mature, catapulting its razor-sharp claw-like corrosive-poison-laced seeds in a 300 feet radius with a loud bang. So, essentially, this tree has a 100m wide "Instant Death" Radius. If it could walk, it would enslave mankind.
  • Y'ever get a papercut? They can attack you even after they've been cut down.
  • When the death rate in New Guinea is broken down by cause, tree-related accidents come at the top of the list. This is mainly from people either climbing coconut trees to harvest the fruit and falling. However, a surprising number of injuries and deaths are from people napping or walking beneath coconut trees and having a ripe coconut fall on their heads. The trees can get up to 25 to 30 meters high, and the nuts can weigh up to two kilos. The impact force from a heavy coconut falling from one of the taller trees can easily crack a skull, and sometimes is fatal.
  • Durian trees, found in Thailand, Malaysia and Indonesia, are even worse: They potentially grow taller than coconut trees, have even heavier fruit which are covered in Spikes of Doom. A falling durian packs enough punch to straight up murder cows. Also, to add insult to injury, they stink to high heaven.
  • The New World version is Brazil nuts. They're big and notoriously tough-shelled.
  • In a less tropical version of the coconut example, you have the sugar pine. It produces enormous pine cones known unsubtly as "widowmaker" cones. Stand beneath them at your own peril.
  • In the Land Down Under, there's eucalyptus trees which are Made of Explodium. What happens that the oil-rich Eucalyptus tree combined with the hot outback sun and a spark in the wrong place can combine to make the tree combust. They don't need to explode to kill you: several subspecies of eucalyptus also known has Gum (or alternatively, widow-makers) have a tendency to shed potentially rather large branches, even on a completely still day. For some of these species, the bigger branches tend to weigh in at a good 15 or so pounds, so one landing on your head from 10 or so feet is a good way to meet your maker.
  • Statistically speaking, you're about ten times as likely to die from falling coconuts as from shark attacks.
  • More a bush than a tree, but the tumbleweeds that add local color to movie Westerns can actually be rather dangerous, as they can grow to the size of an ATV and are covered in sharp edges and thorns. In drought years when they tend to flourish, large swarms of wind-blown tumblers have caused drivers to crash by covering their windshields, and their dry, bristling branches are highly flammable, meaning if one gets blown through a campfire it can bounce along for miles, setting the countryside ablaze.
  • Another native of the Land Down Under is the Gympie Gympie Tree, which looks deceptively harmless. If you so much as brush up against any part of this plant- the stem, the fruit, even the leaves- you will immediately struck with some of the the worst pain you could ever possibly experience. This is because the plant is coated in very fine hairs tipped with silica pods that easily penetrate human skin, releasing a potent, pain-inducing compound. The pain from this is so intense that it's killed humans, dogs, and even horses either through shock or pain-induced suicide. This pain can last for months or even years, recurring from even the slightest touch or motion. And did we mention the Gympie Gympie sheds its hairs constantly, and they can be carried by the wind into your eyes and nose?
