Belly Mouth

GET IN MAH BELLAY!

A classic trope, the "belly mouth" or "bellymaw" is where a creature/character/machine actually has a mouth directly outside from its place in the body. Sometimes it's disguised and well hidden, other times it's used as an intimidation tool, or sign to state that the character in question is a Villainous Glutton, a Big Eater or somewhere in between when regarding the consumption of vast quantities in (usually) organic material, even going so far as to make it out to be a horrifying monster, or from time to time, a comical character.

Note: In some cases, the belly mouth is actually a symbiotic creature, or has a mind of its own, that uses the host's body to get about, while adding an additional passage to the stomach via which more consumables can enter.

For a much more Freudian, disturbing variation on the "mouth in the wrong place" theme, see Vagina Dentata.

Compare Cephalothorax, where the only mouth the creature has is, technically, on its belly.

Sub-Trope of Too Many Mouths.

  • The Gurren Lagann, although this is because the chest and abdomen areas of the combined mech are Gurren's "face" when separated.

  • In Digimon Fusion, Splashmon's quadrupedal water tiger form comprises the quadrupedal lower half of GrandGeneramon, a centauroid mashup of the Seven Death Generals. The placement of the humanoid upper body above it turns what was once Splashmon's regular mouth into a belly-mouth relative to GrandGeneramon's already bizarre body plan. It still has the water-based Breath Weapon, too.
  • Revivemon of Digimon Universe: App Monsters is a black dragon with a belly-face that conceals a cannon in its mouth. It's ambiguous as to whether or not it's just part of his armor since it's made of the same metallic material as the rest of his body.

• A few demons have this in 3×3 Eyes: notable cases include Zhou Gui in his One-Winged Angel form (the "mouth" in this case being a black-hole like gateway to the Subspace lined with fangs), and the Hyoma Clan Warrior Prince Galga, who seems to have a knack for forming a whole dragon head and neck from his abdomen and use it to chew and char his enemies. On the other side, Coco has a massive fanged mouth on his chest, but doesn't appear to be functional.
• Azi Dahaka, one half of the Big Bad Duumvirate in Future Card Buddyfight's first and third seasons, has a face where his chest should be, complete with a fang-filled maw on his abdomen.

  [Spider-guy crawls off, revealing himself to be a separate creature]
  Cephalothorax: Yeah! Weirdo!
• The Snapping Turks in Yellow Submarine.

The vamp was dubbed the "Mouth-Bitch" during production and was infamous for how gruesome it was, so much so that Quentin Tarantino reportedly refused to go near it. It was designed this way as a tribute to The Thing (1982) in reference to the scene mentioned below, only with the more lethal and gruesome function of biting off and devouring the victim's head.
• Professor Ragnar gets one at the climax of Ghoulies III: Ghoulies Go to College! when the dark magic gets a hold on him.

• Vaka-Waka from Mixels, though with the twist that each are their own personality and person. Despite the fact both of them have the ability to eat standardly, Waka, the stomach mouth, is forced to handle the digestion and "output", which isn't good when Vaka eats things like fish heads or battery acid...

Video Games

• Dracula's final form in Castlevania: Bloodlines is a winged demon with wings, fangs, horns, and a second mouth, not in his belly, but his crotch.
• Bishamon of Darkstalkers series. The mouth in question actually belongs to the armor he wears, not to him, but since he's possessed by the armor, it fits.
• The Fallen from Devil May Cry 3: Dante's Awakening normally appear to be angels with six wings; two on their back, outstretched, two covering (or acting as) their legs, and two acting as arms, the latter wings hold a divine sword and act as a shield, protecting the Fallen from attacks. You can break their shield-wings to reveal a grotesque belly mouth, which, aside from looking pretty horrifying, also serves as the angel's weak spot.
• Goliath from Devil May Cry 5 can suck anything close to him into the mouth on his stomach and spit out a huge fire storm or magical fire balls in return.
• Ghom, the Lord of Gluttony and one of the Act III bosses from Diablo III sports such a mouth, which is much larger than his actual mouth on top. This guy takes being a Big Eater to truly nightmarish degrees, such that it is implied that captured soldiers were either eaten by Ghom or fed to others to fatten them up before they were eaten by Ghom.
• The One-Winged Angel form of Necrosaro/Death Psaro, the final boss in Dragon Quest IV, which looks a bit similar to Satannish above.

• Harmful Park have a the giant King boss, whose bulging belly has a smiley face that tries flattening itself on your player characters.
• The Big Bad of Holy Umbrella has one of these. During his short stint as a playable character, you can shoot powerful flame attacks from it. Exaggerated by the final boss, who not only sports one, but his body is made entirely out of interlocked metallic faces.
• Half-Life
  • The series's regular zombies have their torsos ripped open. They are known to stuff food into their chest "mouths".
  • The more mutated gonome zombies from Opposing Force as well.
• The Ducky Goose and Drak Quack Dream Eaters in Kingdom Hearts 3D [Dream Drop Distance] have a very prominent one, from which they generate various party toys and fireworks to attack with. The former's Japanese name (Haraguchi Ahiru) even translates literally into "belly mouth duck". However, the way their heads hang back limply when they run, coupled with the suspiciously eye-like markings above their belly mouths can make one question whether or not they're really just Waddling Heads with a fake head on top.
• King Dedede gets one during the second phase of his boss fight in Kirby's Dream Land 3, courtesy of being being possessed by Dark Matter. Besides an attack where he uses said mouth to try and bite you, he can also reveal an eye to shoot dark pellets at you. This returns in a similar fashion in Kirby 64: The Crystal Shards, though thanks to Dedede being a miniboss this time around, it's much less dangerous.
  • This trope made a surprise (and rather darker) return in Kirby: Triple Deluxe, where Shadow Dedede uses it. This time around there's no getting chased and avoiding being eaten, though in exchange the dark energy fired is much more powerful, sometimes ranging into full Bullet Hell. Not only that, but whenever the jaw opens, what seems to be blood flies out.
  • And then King D-Mind uses it in a similar manner to that of Shadow Dedede listed above in Team Kirby Clash Deluxe and Super Kirby Clash, though without the blood this time. But then it's exaggerated when he Turns Red: The belly grows to massive proportions and reveals Dark Mind's giant eyeball form inside, and also flies around trying to bite the Kirbies before floating to the top of the screen and firing lasers from the eye.
• In Jiu Xiao you fight a giant headless demon whose face is located in the belly.
• The Chocobo/Earth Eater monsters in Lightning Returns: Final Fantasy XIII have one. They use it to unleash their strongest attacks, though their weak spot is also concealed within it.

• My Singing Monsters has Whaill, the plasma quad with not only 5 mouths on its face and hands, but an extra one on its belly. If one listens to their song for too long, they can begin to tear apart the fabric of space time.
• Pokémon has four:
  • Pokémon Ruby and Sapphire introduced Metagross, though this is more a consequence of its body type. Its Pokédex entry in Sapphire and some later games state that it eats its prey using the large mouth on its stomach.
  • Pokémon Diamond and Pearl introduced Dusknoir, the evolution of Dusclops. According to its Pokédex entry, the mouth leads to the Underworld. It uses it as its actual mouth, given that its "regular" head has no mouth.
  • Pokémon Sun and Moon introduced the Ultra Beast Guzzlord (UB-05 Glutton), which has a small, cone-shaped head mounted on a body with a huge maw and two eyes accompanied by eyebrow-like protrusions. Like Dusknoir, it uses its main belly mouth as its actual mouth.
  • Pokémon Sword and Shield introduced Mr. Rime, the evolution of the Galarian variant of Mr. Mime. It is based on tap dancers, but for a bizarre, inexplicable design choice its actual face is on its torso, and the face on its head remains expressionless. Somehow, it is both creepy as hell and adorable.
• The Gnaar of the Serious Sam series are monsters without a head, containing a big eye and mouth on its torso.
• Mondu, final boss of Genesis "fighting" game Slaughter Sport has a whole face on his ample gut. It can speak (in the game's intro) and flick its tongue as an attack.
• Nightmare from the Soul Series has a mid-section completely compromised of a mouth and teeth.
• Some creatures in Spore
  • An example is seen here with this creation. This creature has mouths and faces all over its body (tail, belly, legs, feet, etc...) which can even detach, including on its belly, and these developed minds of their own. After the small human head was crushed by the feet, it could be considered a Cephalothorax as its only head was on its belly. However, faces formed on the belly mouth’s belly.
• Subnautica: The Shadow Leviathan in Below Zero has a glowing blue mouth on its belly, and uses its centipede-like legs to capture prey (including the player) and drag them inside to be digested alive.
• Super Ghouls 'n' Ghosts: In stage 6, bosses Asutaroto, Nebiroth, and Sardius(the final boss) all have belly mouths. The former two spit out fire while the latter spits out platforms for Arthur to stand on in order to attack Sardius. Mid-boss Astaroth in Ghouls 'n Ghosts also has eyes on his torso and a mouth on his abdomen. Astaroth actually has this in every single appearance of his, and he is also the most recurring antagonist.
• The Belly Juju from Tak 2: The Staff of Dreams. Also, the Belly Mouth is competent, can speak, and demands candy as payment for help. Meanwhile, his actual head is...less so.
• Tekken 5 boss Jinpachi Mishima, in his Devil mode.
• Tech Romancer final boss Goldibus has this in his second form. Which is ironic, since there's no mouth on his actual head. (Interestingly enough, both Jinpachi and Goldibus share the same voice actor, Chikao Ōtsuka)
• The eponymous character in the fighting game Tongue Of The Fatman has one of these.
• Twin Caliber have a giant zombie boss in the Sinister Subway who doesn't have a head, but it does have a giant mouth in it's torso. Which it will try to chew you with.
• Trillion: God of Destruction: It's largely more of a design choice, but Perpell, the Overlord of Gluttony, has one on her dress. Fittingly, she is also a Big Eater.
  • The titular monster has one in all of its forms, and it uses it to fire lasers in its first/titan form. In its true form, it appears as a young woman, much like Perpell. There is a reason for this.
• In Undertale, two of the monsters — Froggit and Knight Knight — have entire faces, complete with mouths, on their abdomens.
• Deltarune features the Spades King, a boss with a mouth belly full of sharp teeth and a spades tongue which he utilizes in his attacks.

  • In The Burning Crusade, fiends such as Omor the Unscarred have a face with a gaping mouth on their chest. Some of them can breathe fire from it.
  • In the Warlords of Draenor version of Hellfire Citadel, the boss Gorefiend possesses this. Part of the fight's mechanic is he'll devour the souls of members of the party, who can then help weaken him from the inside.
• One of the bosses you fight in Dark Souls is the Gaping Dragon, a corrupted glutton whose insatiable appetite has, among other things, caused its entire upper torso to split in half vertically and become an immense snapping mouth.

• In Toukiden, the large Oni Jollox and its palette swap Edax are mountainous humanoid gluttons that have a gaping maw on their bellies that's usually closed. When the Oni is enraged, this mouth opens and the creature bounces along on the ground like an enormous Pac-Man with trailing tentacles.
• In Avencast: Rise of the Mage, the Wolgath are hulking four-armed Mighty Glaciers with Vacuum Mouths protruding from their stomachs, which draw victims into striking range of their massive axes.

• Wonder Boy III: The Dragon's Trap has the Final Boss, the Vampire Dragon, with a second head on his belly. It's as vulnerable as any other dragon's regular head.
• In Warframe, this is Grendel's whole theme. He can use his first ability to absorb enemies into the maw on his gut, then use his second to convert them into a party-wide buff or his third to turn them into a projectile.
