%%* ''VideoGame/{{Athena}}'': The boss of the first world.

%%* ''VideoGame/TheBlackHeart'': Hashi, especially when using his [[OneHitKill ultimate]] [[ManEatingPlant ability]].

* ''Franchise/MortalKombat'': The Living Foresth has talking trees that were ([[UrbanLegendOfZelda falsely]]) rumored to be able to eat the players as a special [[FinishingMove fatality]]. Creator/{{Midway|Games}} took care of this oversight in their later MK games.

* The second-to-last boss of ''VideoGame/DemonFront'', a giant tree monster called "Devil Heart", who can drop [[DeathFromAbove projectiles from above]] the players in increasingly massive quantities as the battle continues. It can also summon ManEatingPlant mooks as backup, including oversized Venus flytraps that chomps on the player, and flowers that spits bullets.

* ''Webcomic/SomethingPositive'': The [[http://www.somethingpositive.net/sp05042002.shtml Redneck Trees]] combine the Rape Trees from ''Franchise/EvilDead'' with the hillbilly rapists from ''Film/{{Deliverance}}'' with horrifying results.

* Not a tree, but similarly massive and sturdy when compared to other freshwater flora: The giant water lily of South America is an aggressive slow-motion attacker of ''other plants'', whirling its heavily-spiked stalks and buds to batter aside floating water-lettuce and clear space for said buds to unfurl. As its huge circular pads unroll, more spikes on the mega-leaves' undersides stab nearby floating plants or shove them whole underwater, inexorably excluding rival vegetation from the big plant's territory. Once established at the water's surface, its giant pads cut off light to any bottom-growing plants and algae nearby, leaving the victorious lily without competitors. Speed up footage of this happening, and you'll swear you're watching a furious BotanicalAbomination at work.

* ''Fanfic/AFrozenFlower'': When Till and Orchid run away from Grimes and his group, as well as Olive and Otto, they are attacked by the living vines that invade Sector 21 at nighttime. One knocks out Till and renders her unconscious, while another traps Orchid for a brief while before she frees herself by using sparks of her ''lambero'' energy.

As its huge circular pads unroll, more spikes on the mega-leaves' undersides stab nearby floating plants or shove them whole underwater, inexorably excluding smaller vegetation from the bigger plant's territory. Once established at the water's surface, its giant pads cut off light to any bottom-growing plants and algae nearby, leaving the victorious lily without competitors. Speed up footage of this happening, and you'll swear you're watching a furious BotanicalAbomination at work.

* ''Film/MenInBlack'': The plot of the ExpandedUniverse 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!).

* ''VideoGame/{{Stellaris}}'': Apart from the possibility of a hostile empire or marauder horde using the tree portraits, there's also a possible event for a newly colonized world. In this event, trees migrate across the globe wrecking structures. This can be counteracted by burning the trees to the ground or creating a chemical formula to dissuade them. The latter option has the trees eventually figure out how to avoid your colony permanently, adding modifiers to social research but blocking off a district.

%%* ''VideoGame/ArTonelico2'': Ryuji, the penultimate boss.

* ''WebOriginal/{{Mortasheen}}'': There are a few, like the body-horror-inflicting [[http://www.bogleech.com/mortasheen/willoweird.htm Willoweird]] and the [[OurZombiesAreDifferent mostly-zombie-tissue]] [[http://www.bogleech.com/mortasheen/wormroot.htm Wormroot]].

* ''Fanfic/PrettyCureMiraiSpark'': The sentient Rage Tree, whose fruits give rise to the MonsterOfTheWeek and which feeds off of liquid despair.

** ''Manga/SteelBallRun'': Sugar Mountain's Stand takes the form of a tree and imposes a dangerous effect of being absorbed into it if anyone is unable to fulfill the use of the items they were given or try to escape with deception.
** ''Manga/JoJolion'': Downplayed with The Gingko Trees. The trees aren't fully sentient or malicious since their Stand ability only works by creating a pathway with their leaves and sending any person [[TeleportInterdiction to a location instantly]]. But this provides some cons in the area to use the trees to trick nearby civilians for extortion money.

* In ''Manga/{{Naruto}}'' [[spoiler:the original form of the Ten-Tails]] is the WorldTree. [[spoiler: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 FinalBattle.]]

* ''Manga/SplatterFilm'', a short manga by Creator/JunjiIto, features one of these. The characters become addicted to some strange "honey", only for each 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.

* ''VideoGame/DragonQuest'': Killer Trees are common enemies.

* ''[[https://www.fimfiction.net/story/534583/i-dont-want-to-be-a-tree-anymore I Don't Want to Be a Tree Anymore]]'': The trees of the Everfree Forest are aware, capable of communication, and live lives dominated by absolute hatred of everything else -- the birds and squirrels that eat their seeds, the larger animals that break and bruise them with their passage, the traitors growing in parks and orchards in civilized lands were once forest, and ''especially'' the ponies that turned vast primordial wildernesses into pastoral fields. This is an impotent hatred for the most part... but, if sufficiently motivated, they can slowly begin to move...

* In ''Fanfic/OpeningDangerousGates'', a demon possesses a redwood tree and terrorizes a forest. It also spawns smaller, mobile tree demons.

* In the ''Literature/JuniperSawfeather'' novel ''Whisper of the Woods'', Ronnie makes fun of the idea that a {{treant}} is anything other than an ordinary tree. The tree gets revenge by creating a ladder of thorns to lure him into climbing twenty feet up. Then it stabs him with the thorns, knocks him to the ground with a branch, and kicks him away with its roots. Ronnie survives with multiple broken bones and a concussion.

* 'Literature/TheIllearthWar'' 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.

* ''WesternAnimation/SamuraiJack'': Aku is not a tree per se, so much as he is an EldritchAbomination 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 [[ReducedToDust Aku disintegrates him.]]

* ''LightNovel/UndefeatedBahamutChronicle'': Yggdrasil, 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 [[HealingFactor regeneration]], [[AdaptiveAbility adapting to resist any attack and grow even stronger]], [[CannibalismSuperpower eating Drag-Rides to incorporate their weapons for its own use]], and [[PuppeteerParasite 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.
