You'll never get out alive!
Don't go dreaming, don't go scheming
A man must test his mettle
In a crooked ol' world
Starving in the belly, starving in the belly
Starving in the belly of a whale!"
This, as denoted in The Hero with a Thousand Faces, is the conclusion of the Separation, the first phase of The Hero's Journey: "The hero, instead of conquering or conciliating the power of the threshold, is swallowed into the unknown, and would appear to have died." There is no turning back from this point. This is The Hero's point of no return where he resigns himself to the difficult task ahead. Forward march to the Road of Trials!
It may not be entirely pleasant there's a reason Campbell compares it with dying. It is often the moment of greatest personal danger for the hero. The Hero can move forward by defeating the Threshold Guardians, but also by being destroyed by them.
The Trope Maker Is Jonah of The Bible, who, having been called by God, flees from Him unsuccessfully aboard a ship, and, the ship subsequently being caught in a terrible and dangerous storm, finally surrenders to God's will by throwing himself overboard; here, a "great fish", at God's command, swallows him and stores him within its belly for three days, during which Jonah accepts God's original call, and after which he is spewed out onto land by the beast, again at God's command. There is a reason Campbell calls this step "The Belly of the Whale".

- The Eclipse and its aftermath serve as this in Berserk. His best friend turned betrayer and demon god, his comrades dead, and his lover gone insane, Guts accepts that nothing will ever be the same again and takes on the quest to slay apostles, even remarking to himself that he is going into the void all alone. It later turns out that setting out on a quest for revenge against Griffith was a mistake even worse than leaving Griffith behind, as it meant leaving Casca behind to deal with her trauma alone, as well as almost losing himself to his hatred for Griffith and the demons.
- In Fullmetal Alchemist Edward and Alphonse Elric burning down their childhood home marks this for them, as they declared that there was no turning back on their quest to get their original bodies back.

Jonathan decides to burn down his family's mansion in an attempt to destroy Dio, and this confrontation ends the more "grounded" arc of this part and leads into the more "bizarre" arc of Jonathan learning the ways of Hamon and Dio taking over a small town.
- One Step Backwards And Three Forwards opens with Hawkmoth winning, with reality being rewritten by the Wishes he and his followers make on the united Ladybug and Black Cat Miraculi. Marinette finds herself as one of the only ones left who recalls the way the world was before, with her only other ally being Felix Agreste — aka the original Adrien, who had his memories and mind split off from this world's Adrien as a result of Lila Wishing that Adrien was her trophy boyfriend. With life as they knew it dramatically altered, the pair begin a long battle to regain all the stolen Miraculi and set things right.
- Finding Nemo has an accidental example: Marlin and Dory are swallowed by a whale, which marks their final step in the journey to Australia (and a variant: instead of preceding the Road of Trials, it's the end of it, though not of Marlin's privations).
- In Loving Vincent, Armand Roulin is portrayed as a restless young man who wasn't fond of the late Vincent van Gogh and has no interest in taking an undelivered letter to Theo van Gogh. His father Joseph, the postmaster, manages to guilt him into it.

- Luke's is when he boards the Death Star.
- Rey's comes when she accepts her family is never coming back, and seeks out Luke to begin her training.
- The Matrix: After Neo swallows the red pill and awakes in his battery pod outside the matrix. The whole sequence is a very literal "rebirth" into his new world, with a naked, bald Neo covered in goop, breaking out of a translucent sac and being dumped down a chute, only to wake up disoriented and helpless in a hospital bed.

- In The Wheel of Time, Rand must enter a series of archways to learn the history of his true native people, the Aiel. If he stops or turns back at any point during this journey, he will never return.
- In Tad Williams's Memory, Sorrow and Thorn, Simon's first journey beneath the tunnels of the Hayholt on the heels of his mentor's Heroic Sacrifice is the point where his journey becomes irrevocable. It also includes the literal metaphor of being "swallowed up" by the earth, followed by his emergence, alone, starving, and companionless.
- In The Quest for Saint Camber, Kelson and Dhugal are swept away in a mudslide and washed into an underground cave system behind a waterfall. They follow the cavernous tunnels looking for an escape route and are forced to break into the tombs of the Servants of Saint Camber (who have been in hiding for two centuries due to the anti-Deryni persecutions) to escape. To avoid death sentences for despoiling the Servants' graves, Kelson must undergo a ritual trial called cruaidh-dheuchainn; he's sent naked into an underground chapel that has chemical fumes used to induce visions, and he must stay there overnight and report whether or not Camber visits him. After this, he's ready to return to his capital and face the task of taking his throne back from his cousin Conall.
- Cleanly marked in Harry Potter and the Philosopher's Stone: when Harry is on the Hogwarts Express, he thinks, "He didn't know where he was going... but it had to be better than what he was leaving behind."
- In the Whateley Universe, it's the moment when Ayla Goodkind leaves the 'normal' world and rides into Superhero School Whateley Academy. Given that 'Goodkind' means 'mutant-hating enemy' in this world, it's pretty much like someone named Hitler going to a university in Jerusalem.
- In Neverwhere, the Ordeal that Richard goes through. Other characters note that he seems more mature after passing it.
- In The Lord of the Rings: When the Fellowship enters Moria, and when Frodo agrees to be the ringbearer for the Fellowship's journey at the council of Elrond.
- In The Count of Monte Cristo, Edmond Dantès is initially a benign, trusting, and naive young man with a happy future ahead of him. Then he's falsely imprisoned. He initially hopes that he'll receive justice and return to his friends. But after four years, he realizes that he'll never be released. This is the trope-point where there is no going back to his old life, only ahead... It initially drives him to despair and a suicide attempt. But the unexpected arrival of a fellow prisoner, the remarkable Abbe Faria, turns his thoughts in a new direction, toward escape and revenge. This also marks a change in Dantès's character.
- Halfway through Pact, Blake Thorburn, the viewpoint character, has his connections to the outside world eaten by a demon, causing him to become an Unperson and trapping him in the Drains, where he's forced to confront hard truths about himself and his life, ultimately emerging more supernatural creature than human.
- In Below, Brenish and Raden fall off a cliff during a battle, leaving them in an uncharted part of the ruins with only a rough idea how to reunite with their party. Brenish is effectively on his own for the first time, having to put his knowledge to the test and even taking a lead role in combat because of Raden's injury.
- In Out of the Dark, Dracula has given the hostile aliens every opportunity to leave and stop killing humans. Finally, when the aliens decide to just wipe out the entire human race, he's had enough, turns a bunch of soldiers into vampires and assaults the alien fleet.
- Buck Rogers in the 25th Century: In the TV cut of movie pilot, there is a epilogue where Buck is clearly still coming to terms with losing everythng he knew due to being a 500 year old Human Popsicle. Dr. Huer and Wilma offers Buck a position at the Earth Defense Directorate. Buck, feeling that he is hopelessly out of date, is reluctant to join and continues to mope around during the first part of the first episode of the TV series proper. Buck is curious about Earth's latest Big Bad threat but he is politely denied any details, of course, since it's Classified Information. As this was coming from Dr. Huer and Wilma (Red Pill, Blue Pill and the fact that they even bothered to inform him at all), it was made to sound much more like a second Call to Adventure, however, since Buck was still Desperately Looking for a Purpose in Life. At that point, Buck realizes that he must join if he's to have any real purpose.
- The Biblical story of Jonah in the belly of the whale, where Jonah had no choice but to accept God's plans for him (although the Hebrew word used in the Old Testament is fish "דג" NOT whale "לִוְיָתָן").
- The Odyssey: The Belly of the Whale for Odysseus is pretty much the moment Agamemnon drafts him into the Trojan War; his life goes downhill from there for the next TWENTY YEARS (10 at war with Troy, 10 trying to get home but with a sizable chunk of time on Calypso's island). Looking at the events of the Odyssey, the moment of hubris in which infuriates Poseidon would probably count.
- Final Fantasy IV: Cecil is shipwrecked and washed up, all alone, near Mysidia, a city he had attacked and plundered before the start of the game. He has no choice now but to walk the road of atonement.
- In Baten Kaitos, after the first big Wham Episode, Xelha finds herself locked up alone in the Imperial Fortress. It's only with the help of the Guardian Spirit that she escapes. And more literally, Baten Kaitos is a star in the Cetus constellation. Yes, it is the belly of the whale.
- In The Legend of Zelda series, this is often done both as part of the beginning of the game, and when the first act is done and the second act starts in an event called the "mid-game plot twist."
- In The Legend of Zelda: A Link to the Past, this comes when he rescues Zelda from Agahnim and becomes a fugitive. Later, it comes again when Agahnim has re-captured Zelda and Link goes to confront him, only to be sent to the Dark World at the end of their encounter.
- In The Legend of Zelda: Ocarina of Time, when the Great Deku Tree dies and Link must leave the forest, and later when Link is sealed in the Sacred Realm for a seven-year coma, only to awaken to a Crapsack World in which the first thing he sees is a ReDead.
- In The Legend of Zelda: The Wind Waker, when the pirates first drop Link off at the Forsaken Fortress. Arguably it's immediately after his defeat at the Forsaken Fortress. When he's sent to the fortress, he's still an overconfident kid. After he was tossed into the ocean and rescued, THAT was when he wised up to what he really needed to do. The mid-game twist occurs when Link first encounters Ganondorf with the Master Sword, only to find that it has lost its power.
- In The Legend of Zelda: Twilight Princess, when Link finds himself turned into a wolf and locked in the twilit Hyrule Castle. The mid-game twist occurs when Zant blindsides Link and takes the Fused Shadows they worked hard to get.
- In The Legend of Zelda: Majora's Mask, after the Happy Mask Salesman has taught him the Song of Healing and given him his quest.
- In The Legend of Zelda: Skyward Sword, when Link finally makes the jump from the safety of The Sky to the desolate Surface below.
- Played with interestingly in The Legend of Zelda: Breath of the Wild, where this part of the story actually happens before the game proper. As told by one of the flashbacks, Link nearly died defending Zelda from the corrupted Guardians, but right after he collapsed, the Master Sword's spirit, Fi, told Zelda to take him to the Shrine of Resurrection where he would be healed over the course of a century. However, the healing process caused him to lose his memory, thus necessitating him to restore it.
- Kingdom Hearts:
- Sora does this twice. Once in the sub-journey that is the first game, when he separates his heart from his body, and again and more fitting of the trope in his series-long character arc when his heart is shattered entirely and he has to put it back together and heal before he gets another chance to pass the official Hero's Test Yen Sid was giving.
- Sora arguably had a couple of these moments in the first game. The first was when his homeworld was destroyed and he more or less washed up on Traverse Town. The second happens when he loses the Keyblade as well as Donald and Goofy to Riku, forcing him to rely on his own strength and tenacity for the first time since starting his journey rather than using the Keyblade as a handicap.
- The initiation ritual for a Liir joining the Black Swimmers in Sword of the Stars fits this to a tee. First, he goes through what is basically a funeral, where his loved ones circle him, sing to him, and touch him one last time. After he is handed over to the Black Swimmers, his lungs are filled with the oxygenated fluid that Liir warships use instead of atmosphere. To the recruit, this is very much like drowning, and indeed the first day of training is called "Drowning Day". After he has been reborn, not as a Liir, but as a Black Swimmer, he will undergo his military training.
- In Super Robot Wars Alpha and OG, Campbellian Hero archetype Ryusei Date's symbolic death and rebirth comes when he and the rest of the SRX team are forced to use their dangerous, untested Combining Mecha in the middle of battle and re-emerge as the gigantic Super Robot X.
- Cave Story has a memorable case. After the reasonably light-hearted adventuring through Grasstown and the Sand Zone, Quote sees Toroko die in front of him, and is cast into the Labyrinth by Misery.
- Assassin's Creed: Revelations is this for Desmond Miles. He has fallen into a comatose state after being forced to kill Lucy Stillman, and the only way for him to ever wake up is to relive Altaïr Ibn-La'Ahad and Ezio Auditore's memories until there's nothing left for him to relive, as well as coming to terms with his troubled past, the fact he is an Assassin and the role he has to play.
- In Gunnerkrigg Court, this moment comes in chapter 7, when Antimony sees Robot S13 on the bridge and rushes out to help, knowing that she'll get in trouble for it. She then gets pushed off the bridge and spends the night trapped in the gorge.
- In Tower of God, the secret plot of Headon and Yu Hansung requires Twenty-Fifth Bam to disappear from the face of the earth and the eyes of King Jahad. Apparently, it was most effective when he was killed by the person he was looking up to and searching for just when everybody thought it would be just fine. Not only is this a staged death, it is the final sladgehammer stroke that destroys Bam's innocence and replaces it with emotional emptiness.
- Avatar: The Last Airbender: In "The Southern Air Temple", after Zuko's attack on the Southern Water Tribe forced Aang to accept his identity as the Avatar, Aang realizes "I really am the last Airbender," and he becomes aware of the danger of the Avatar State.
- 70 years later in The Legend of Korra, Aang's successor Korra manages to escape some Threshold Guardians (the Order of the White Lotus) and conciliate others (Lin Bei Fong and Tenzin) and finds herself firmly set in Republic City of Adventure.
