A Brute Wyvern with long arms whose forearms and horn are covered in an explosive slime mold, that it has a symbiotic relationship with. ''4 Ultimate'' added the Raging Brachydios variant with a separate Icon, yet it does not have a separate name in-game from an ordinary Brachydios, much like the Savage Deviljho in ''3 Ultimate''. ''Explore'' features two variant, one that looks like [[Anime/NeonGenesisEvangelion Unit 01]] and another that has Ice powers.

A ''Smilodon''-like Pseudo Flying Wyvern that prowls the tundra. Sporting white scales, amber fangs, and wing-arms, Barioths tear through their enemies with body slams, tail swipes, and a breath attack that can encase any unfortunate traveler in snow. Strong and fast, Barioth is the frosty king of the snow lands as this monster hunts with a stern might. ''Portable 3rd'' introduces a yellow subspecies that prowls the deserts. ''World: Iceborne'' introduces a more rugged, ice-covered variant that creates ice to trap its enemies.

A volcano-dwelling Brute Wyvern covered in ores extracted from the rocks it eats. It attacks with slamming its massive jaw onto the ground (which can cause volcanic rocks to explode) and a few fire-elemental attacks. ''Portable 3rd'' introduces a Subspecies made of steel. ''Generations'' adds the deviant Crystalbeard Uragaan. A purple-and-orange Halloween-themed variant with a Jack-O-Lantern chin appears in ''Explore''.

A ''Smilodon''-like Pseudo Flying Wyvern that prowls the Tundra. Sporting white scales, amber fangs, and wing-arms, Barioths tear through their enemies with body slams, tail swipes, and a breath attack that can encase any unfortunate traveler in snow. ''Portable 3rd'' introduced a yellow subspecies that prowls the deserts. ''World: Iceborne'' introduces a more rugged, ice-covered variant that creates ice to slow down hunters.

A frightening and powerful Brute Wyvern (essentially the games' answer to Franchise/{{Godzilla}}). This [[{{Kaiju}} gigantic monster]] resembles a monstrous ''Tyrannosaurus rex'' and it can overpower most non-Elder Dragon monsters as it wanders from place to place. With a [[SuperStrength large muscular body]] covered with spikes, a face [[MoreTeethThanTheOsmondFamily full of sharp teeth]], deadly [[AntiMagic Dragon element breath attacks]] and a [[HorrorHunger ravenous appetite]] that ''never'' goes away, Deviljho instinctively causes fear, death and destruction wherever it goes. It only appears in High-Rank expeditions/quests... [[DropInNemesis whether you're hunting for one or not]]. ''3 Ultimate'' introduces a form that is perpetually hungry, sporting a Dragonblight haze over its head when angered and an even more ferocious battle style. ''Explore'' features a variant with no skin, much like the [[Manga/AttackOnTitan Colossal Titan]].

A large Brute Wyvern that's essentially the games' answer to Franchise/{{Godzilla}}. A {{Kaiju}} resembling a monstrous ''Tyrannosaurus rex'' with teeth and spikes all over, it wanders from place to place, devastating any place it goes to sate its hunger. Infamously strong and fast.

* DamageSpongeBoss: Alatreon's health in ''Iceborne'' stands tall at around 52,500 HP in solo play, scaling up to 118,150 HP with 3 or more hunters. To put in perspective, the only monsters that can surpass its durability are Safi'jiiva,[[note]]Has much less raw HP at 20,000 scaling up to 40,000, but is capable of frequently healing to full if you haven't depleted all its energy[[/note]] MR Kulve Taroth,[[note]]54,000 HP that scales up to 108,000, meaning it'll have more health when solo but less with a full party[[/note]] Arch-Tempered Velkhana,[[note]]57,600 HP that scales up to 138,240[[/note]] Ancient Leshen,[[note]]67,500 HP, but with no multiplayer scaling[[/note]], and Fatalis.[[note]]66,000 HP that scales up to 171,000[[/note]]. Additionally, elemental damage thresholds to whittle down Escaton Judgement's full power also become significantly higher in multiplayer, making it unwise to party up if not everyone can pull their weight in the frantic DPS check.

* TurnsRed: Quite literally, as the red spots on its body will glow brightly and more prominently as it gets angrier.

** Inverted, in a sense. Apex monsters couldn't be knocked into a Wyvern Riding state period in base ''Rise'', until ''Sunbreak'' allowed Apex Zingore to do so under one very specific circumstance: [[spoiler:facing off against [[TheRival Amatsu]] in a Turf War, with Zingore's presence requiring Utsushi as a Follower]].

* AllYourPowersCombined: Subverted. Alatreon may have access to all elements except Water, but it cannot use them all at the same time; it may only use Dragon and Fire while on the ground and Ice and Electricity for a fixed while when flying. In ''Iceborne'', it gains the ability to use water at long last, though it's not so much water as it is dousing oil that ignites you when hit by Alatreon's fire attacks.

* DamageSpongeBoss: Alatreon's health in ''Iceborne'' stands tall at around 52,500 HP in solo play, scaling up to around 118,000 HP with a full hunting party. To put in perspective, only the Ancient Leshen and Fatalis surpasses it with around 60,000 HP (though it does not scale up with multiplayer) and 66/171,000 HP respectively. Additionally, elemental damage thresholds to whittle down Escaton Judgement's full power also become significantly higher in multiplayer, making it unwise to party up if not everyone can pull their weight in the frantic DPS check.

* MadeOfPlasticine: In ''Iceborne'', its horns have an ''absurdly'' low threshold for breaking them, possibly to compensate for Alatreon's [[LightningBruiser ferocity.]] In fact, they're so brittle that they'll just snap right off after slamming it into the wall with the Clutch Claw once or twice. Good thing, too, as those horns allow it to switch to the opposite element, rendering your weapon about as effective as a wet noodle if it's the same element.

* TakesOneToKillOne: Inverted in that the best element to take against Alatreon in ''Iceborne'' is the opposing one-- Fire against its Ice Active state and vice-versa. Observant hunters will notice that Alatreon will start in a given state depending on its quest, with Blazing Black Twilight and The Evening Star for Fire Active starts and Dawn of the Death Star for Ice Active starts. However, in order to stop Alatreon from swapping into the opposing active state and shutting down all of your elemental damage, you will need to break its horn while it is in Dragon Active state. Fortunately, Fire and Ice still do respectable damage to the monster when it is in Dragon Active.

* TacticalSuicideBoss: Once depowered, it will eventually go through a lengthy recharging process. This allots you a sizable window to wail on it (preferably its head, which may interrupt its charging) or, as of ''Iceborne'', slap it in the face a couple times with the Clutch Claw and toss it into a wall with a Flinch Shot.

** The Redhelm Arzuros. Arzuros used to be the ButtMonkey for the player base, but the Redhelm Arzuros is acknowledged by a significant portion of the player base as the toughest monster among the 10 deviant monsters, which are basically all [[BonusBoss Bonus Bosses]] on their own right.

* BonusBoss: Abyssal Lagiacrus is one of three monsters that does not need to be defeated to fight Hallowed Jhen Mohran.

* BonusBoss: Savage Deviljho does not need to be defeated to fight Hallowed Jhen Mohran.

* BonusBoss: Hallowed Jhen Mohran can only be encountered after defeating (slaying or capturing; repelling doesn't count) every large monster except Abyssal Lagiacrus, Lucent Nargacuga, and Savage Deviljho.

** From its debut and up through the various entries of the 4th generation Zinogre was part of the set of monsters with the distinction of being the only members of their class, Fanged Wyvern specifically in this case (the other being Nerscylla as the sole Temnoceran, until ''Rise'' added Rakna-Kadaki). ''World'' would go on to add several new monsters to the classification all at once, including two which would essentially split the makeup of Zinogre itself (Tobi-Kadachi gets its element typing while Odogaron gets its canine features and strength). ''Rise'' would also add Magnamalo to the list.

* DamnYouMuscleMemory: If you think that Brachydios will be just like every other Brute Wyvern and just charge at you until the Popo come home, you're in for a rude awakening as it comes at you with [[JustForPun dynamite punches]] with the level of finesse you'd expect from a boxer.
