Each area has its own battle theme, sometimes named after a monster hunted there. Third Generation
- Tremble of the Sea and Land (Lagiacrus) forms the greater part of Tri's intro, and with all the hunting you do in the Deserted Island/Moga Woods over the course of the game, you will be hearing it a lot.
- The theme for the Flooded Forest, Trap of the Muddy Stream (Gobul), is a heavily Jaws-inspired theme perfect for battles that usually end up underwater sooner or later.
- Subzero White Knight (Barioth) plays in the Frozen Tundra, a mix of ethereal chimes and pounding drums. Just watch out of the Saber-toothed Dragon-Cat trying to eviscerate you. You first encounter this theme while fighting Gigginox, but it's equally fitting as Gigginox's fighting style is also wild and chaotic, sometimes involving thrashing about, which is what makes the piano so fitting.
- Sound of the Great Mountain (Agnaktor), the theme for the Volcano. A truly exceptional theme for the most heated battles in Tri.
- Golden Reminiscence (Kecha Wacha), the battle theme for Ancestral Steppe. It serves as an amazing introduction for one of the first bosses in the game that isn't Great Jaggi, but the bombastic brass fits any monster using its theme just as well.
- Predator of Darkness (Nerscylla), the theme for the Sunken Hollow. A very dark theme befitting of a frightening area that is full of giant cobwebs and dangling Gypceros corpses and is home to the Nerscylla. It well underscores the first major trial that hunters in the Gathering Hall must face: Hunting a Nerscylla in the Sunken Hollow for a promotion to HR 2.
- Fangs Lurking on the Surface of Ice (Zamtrios), the theme for the Frozen Seaway. With its haunting string instruments and Jaws-like feel, not only does it fit an area that's filled with freezing water, it's a perfect match for Zamtrios in every aspect of its fight. From Zamtrios swimming beneath the ice, to bouncing and rolling around while inflated, it's exactly the song you'd expect a giant shark frog to have. A shame it's one of the most underused songs in the series.note
- The fourth generation's Arena theme has a medieval feel with a somber, yet determined tune, perfect for the many uphill fights that take place within it.
- Not quite an area theme, considering it only plays in town, but Determination! is an amazing song that only plays in one period of time during the game - during the Low Rank Caravan missions when your main Palico has run off on his own to hunt down Gore Magala, and you have to save the brave kitty along with the Ace Cadet and Ace Lancer.
- MHX's new Arena theme, which is an almost western sounding orchestra remix of "Mark of a Hero", the series' main theme.
Unique Battle Music is usually reserved for Elder Dragons, but there are a few that have their own themes. First Generation
- Lao-Shan Lung. In game Lao-Shan Lungs are absolutely massive, yet despite their "Elder Dragon" classification, you only ever fight juveniles. You are supposed to defend a town and make your stand at a specially designed fort, and are fully expected to repel it with the fort intact.
- Kushala Daora. A rather unique Monster in that it constantly has a wind "aura" that is difficult to get through without being blown back. Appears in jungles, mountains, and even towns,and capable of conjuring violent storms alongside their appearances. Fortunately, their "auras" can be weakened when poisoned. Then there's a new theme Kushala Daora receives in Monster Hunter Freedom Unite which is even more dramatic.
- Shen Gaoren. A literal Giant Enemy Crab, and is fought in similar conditions as Lao-Shan Lung. It usually wears the skull of a Lao like a hermit crab as well, and is comparable in height when it fully stands up on its legs.
- Yama Tsukami. The closest the series can get without fully incorporating the Cthulhu deity itself. A floating octopus overgrown with moss and wood that can even summon the swarms of Great Thunderbugs that nest on it. It is acknowledged in game as the oldest living monster.
- Chameleos. An Elder Dragon capable of staying invisible for an extended period of time unless enraged, then this music starts playing. Chameleos is also notorious for stealing often valuable items from hunters with its sticky tounge.
- White Fatalis. A fully mature Fatalis, and requires a hunter to have exceptional timing and skill if they expect to come out on top. One of the few monnsters in the entire series to have a legitimate one hit knock out attack. Can summon red lightning storms as well as periodically shoot an electricity ball from its mouth.
- Nargacuga. The flagship monster of Monster Hunter Freedom Unite. A bat/panther like version of Tigrex, but not as physically strong. Instead, it is insanely fast, and its tail slam can often be a One-Hit KO move for unprepared hunters.
- Ukanlos. Calls the icy mountains its home, and can not only burrow through ice and rock quickly thanks to its shovel chin, it even has command over its element. Should a hunter be able to avoid its speed, power, and ice beams, they will find that weapons made from its materials are some of, if not the strongest in the entire series.
- Teostra and Lunastra. The horns and drums give this song a powerful and savage, yet regal vibe, perfect for fire-breathing dragon lions.
- Moonquake ~ Ceadeus. A heavy tribal drum-beat backing ominous chanting in a made-up language. It underscores the intensity of the fight and the majestic nature of the monster, who lives up to a name that basically evokes "sea god".
- Jhen Mohran is a gigantic, naturally armored, sand-swimming Elder Dragon. Due to the speed it swims at as well as the fact that the sand of the Great Desert you fight him in is dangerous, you are required to travel by boat. A boat fitted with harpoons, cannons, and a giant gong. The music (titled "He Who Rides The Sea Of Sand") really emphasises the danger of the situation as well as the general awesomeness of the fight.
- Deviljho. Deviljho made its debut in the more recent Monster Hunter Tri, yet has quickly earned infamy as one of the most disastrous things that can occur on a hunt. Can easily wipe out an entire group single handedly, has more HP than the final Elder Dragon in the game it starred in, and his theme even overrides the current battle music. Not to mention it directly rips off The Rite of Spring in some parts. The theme song is a reliable way to tell if the Deviljho has invaded your area, because it has priority over all other BGM.
- Zinogre. The flagship monster for Monster Hunter Portable 3rd, and it is essentially a lightning wolf dragon. This is also the first track in the series to use guitar, which instead of sounding out of place, adds even more to the overall intensity of the song and the fight against the monster itself. It's so good that there is a metal version and swing jazz version.
- Alatreon is the second theme to get the electric guitar treatment, and rightly so. Majesty, despair and urgency mark the song's movements as you challenge the very embodiment of elemental chaos in the form of the Brilliant Darkness itself.
- From 3 Ultimate/Tri G, we have the Japanese title monster, Brachydios's theme "Brave Icon". The music has the appropriate swelling intensity and epicness of a monster that can kill you by blowing you up. And just like Zinogre, it has a metal arrangement and swing jazz arrangement.
- Also from Monster Hunter 3 Ultimate is the game's final boss, Dire Miralis. In-game, the Dire Miralis is known as "the devil prophesied to destroy the world," with a theme to match.
- All of these themes pale in comparison to Amatsumagatsuchi's from Monster Hunter Portable 3rd. The first part of the song is quite eerie, and fits the majesty of the monster quite well. But once things get serious in the middle of the storm, the theme trades its ominous nature for an epic composition befitting the Heaven's Catastrophe.
- Tigrex gets a re-orchestrated theme in Monster Hunter 4 that truly captures just how savage and powerful it is.
- Gore Magala gets a sinister sounding theme in the 4th generation.
- Seregios gets an even more ominous theme than his predecessor.
- The end-game boss battle theme is definitely amazing, giving a perfect sense of finality, matching with the climactic showdown with Shagaru Magara, Gore Magala's adult form. Just the kind of final battle theme that screams your desire to eradicate Shagaru Magala off the face of the planet.
- The Apex Monster battle theme is a dark and ominous song that matches the extreme power these monsters possess.
- The first fight against Dalamadur is both an epic and terrifying boss theme, fitting for an abomination of an Elder Dragon who rains down meteors for a hobby.
- Gogmazios' two themes. Yes, the same Gogmazios that embodies the series' Nightmare Fuel, right down to the battle themes.
- Dinovaldo/Glavenus's theme is music for a good brawl, which befits a showdown with a temperamental dinosaur with a sword for a tail.
- Raizekusu/Astalos's theme. Electrifying, aggressive and straightforward; it helps you understand very quickly that the Raizex is out for your blood.
- Gamuto/Gammoth's theme. The Gamuto and its theme have a lot in common; they're rare exceptions. While most themes in the series are perfect battle tunes, conjure up feelings of majesty, or instill dread, few of them sound like an epic undertaking. Most monsters are far cries from what we would see in reality, but the Gamuto's a colossal woolly mammoth, nothing fancy. If you went back in time and hunted a woolly mammoth, this is the theme that'd certainly play.
- Tamamitsune/Mizutsune's theme certainly qualifies as well. The Japanese instruments do an excellent job in conveying the magnificent and elegant aura of this fox-shaped Leviathan; they also set the tone for what is going to be not only a battle, but a dance between enemies. It's art in combat form.
- Osutogaroa's Second Phase. The first phase theme invokes a feeling of uncertainty, which is proper considering you're fighting a monster made of BONES. The second phase? A massively heroic orchestral piece that defines the series; learning about a monster that eats EVERYTHING and going to fight it anyway because you're a goddamn Monster Hunter, you eat monsters bigger than Osutogaroa for breakfast.
- Raviente. Currently the largest known monster in the Monster Hunter series, found exclusively in Monster Hunter Frontier. The picture in the video gives an idea of what a hunter should expect in terms of size.
- Dhisufiroa's theme, which was recently updated to accommodate a new Limit Break he gains after you technically defeat him once during the battle. The theme truly emphasizes Dhisufiroa's raw power and makes for an epic Final Battle.
- Midogaron's theme is intense and intimidating, perfect for the battle with the fire wolf monster in the Volcano.
- Unknown (Black Flying Wyvern). This theme really conveys a You May Panic Now sentiment, as you fight a monster which looks like a demonized Rathian and which has access to incredibly powerful attacks.
- Shantiyen gets four different tracks for each stage of its fight, and all of them are memorable, but special mention has to go to the final track that plays after it downs your ship. In truth, Shantiyen is just is ticked at you for intruding on its territory, but the frantic percussion section and swelling vocals will make it seem like the fate of the world hinges on every swing of your sword.
- Varusaburosu. A piercing flute presiding over heavy percussion and drums, occasional forays into just ominous pounding, strings, and a subtle rattling sound that rears its head throughout the piece come together to basically say, "Get ready to rumble."
