History VideoGame / MonsterHunter3Tri

** In the context of the original ''Monster Hunter Tri'', the monsters Bullfango, Anteka and Nargacuga return (their overall return already happened in ''Portable 3rd''). The latter monster is also accompained by the still-recent Green subspecies (also of ''Portable 3rd'' fame), and also gains a new Rare Species (Lucent) for G Rank.

* ADogNamedPerro: One of the supporting characters intruduced in this expansion is a Felyne who helps the Argosy Captain called Neko (Means Cat). Yes, the clarification encased by the parentheses is part of his name. He also makes an appearance in ''VideoGame/MonsterHunter4 Ultimate'' and both versions of ''VideoGame/MonsterHunterGenerations'', alongside the aforementioned Argosy Captain.

* CastingAShadow: Deviljho is an enormous Brute Wyvern that looks similar to a ''Tyrannosaurus Rex''. When it gets angry, its blood begins boiling (which is reflected in several parts of its skin glowing red) and proceeds to expel a wide Dragon-elemental breath that reduces the victim's attack affinity, which leads to a lower chance of giving critical damage (or even the side effect of inflicting ''less'' damage of their attacks had no affinity to begin with); from ''3 Ultimate'' onwards, this breath nullifies elemental powers instead, as do all other Dragonblight-inflicting attacks.

** The expansion also introduces Stygian Zinogre, a subspecies of Zinogre which trades the ShockAndAwe attributes of its cousin for Dragon-powered dark energy, thanks to its diet of Dracophage bugs. The energy balls it throws from its chest double as a HomingProjectile, hovering for a couple seconds before aiming at the hunter(s). A unique trait is that Strygian Zinogre is actually ''immune'' to the negative effects of the Dragon element, unlike the majority of monsters (including Deviljho and ''Elder Dragons'') that have it but are also paradoxically weak against it.

** Gobul is an enormous Leviathan modeled like an AlluringAnglerfish that is adapted to fight underwater as well as on land, and has a wide array of attacks (such as paralizying opponents with its spikes or stunning nearby hunters and small monsters with an intense flash from its lamp); however, the only water-based attack is has is creating an enormous suction torrent while swimming to swallow preys and inflict serious damage to the hunters caught with it

* AlluringAnglerfish: The Gobul is largely modeled after actual anglerfish, most notably having a large lantern dangling off the front of its hit. Although it fits the trope, it interestingly does not use its lantern as the lure. Instead, it burrows itself into the soil and lures cow-sized herbivores in by disguising its catfish-like barbels as plants, and then it proceeds to swallow them whole with its enormous mouth (it will also casually inhale small schools of fish if they group around it). The lantern, meanwhile, is just used to blind its enemies with bright flashes.

* FastballSpecial: The Deviljho combines this with GrievousHarmWithABody when it picks up a smaller monster such as the Great Jagras or a Kulu-ya-Ku; it chews on the monster for a bit, slinging it around in its jaws like a rag doll, then hucks the monster at you with incredible speed, which hurts both unfortunate parties a ''lot.''

* {{Superboss}}: Hallowed Jhen Mohran is only accessible after the player slays or captures every single large monster (including previous Elder Dragons like regular Jhen Mohran and Alatreon) except Savage Deviljho, Lucent Nargacuga and Abyssal Lagiacrus (which happen to be Bonus Bosses on their own; as Savage Deviljho can only be fought in quests with unstable environments or alternatively through a DLC quest, Lucent Nargacuga is unlocked after reaching HR 40, and Abyssal Lagiacrus is unlocked after reaching HR 70).
