Newton's first law of boss battles: it's not dead if it's not hemorrhaging from every part of its body.
"Far below, life-laden shadows pulse to the unrelenting rhythm of a beating heart."
Every once in a while, video game characters (and rarely non-video game characters) somehow get into a "Fantastic Voyage" Plot inside a giant monster, usually to kill said giant monster from within. As we all know, the heart is the Weak Point for many a creature (i.e. for those who have it), so the logical course is to go straight there.
Naturally, the heart (whether organic or a mechanical replacement still serving to keep the creature alive) is often made into a boss, usually unable to move from its location but somehow armed with an endless supply of Mooks as a line of defense. It may also sometimes have weaponry itself, such as using veins as Combat Tentacles or firing projectile attacks. Either way, the fight only ends when the heart itself is destroyed.
Part of Evil Is Visceral. A subtrope both of Attack on the Heart and Horrifying Heart, and a specific type of Boss Battle. Organic Sister Trope to Reactor Boss. Will usually involve Womb Level as a prerequisite. Compare Belly of the Boss, where the boss specifically swallows the player character and they have to fight it from the inside out, usually in the mouth or stomach.

Gaming Examples
Action
- Altered Beast: Guardian of the Realms: "Dreamscape", the fourteenth stage of the game, features a giant heart as its final boss. The heart is made up of five pieces that attack one at a time, each one shooting pellet-like things at the player character until the segment is destroyed.
- Chaos Heat: A mutation strain outbreak in a Tokyo bio-research facility wiped out all the staff and infests the place with mutants, requiring Rick (the player character) to spend the entire game battling infected civilians and mutated monstrosities while trying to seek the core responsible for the incident. He eventually faces the Mutant Core Final Boss in the lab's center who assumes a trio of forms to fight Rick — firstly a giant Faceless Eye, then a humanoid Bishōnen Line, and finally a giant, floating, beating heart surrounded by Combat Tentacles.
- Splatterhouse: The Womb Level has a beating heart at the end, with a Kaizo Trap of acidic blood that bursts out when you kill it.

The second phase of the fight takes place in the chamber where Gaia's heart is housed, and while the main boss in the room is actually Zeus and the minions he summons, Kratos still has to whittle down the health of both he and Gaia's heart before impaling them simultaneously, killing Gaia and shattering her body as a result, while leaving a still-living Zeus for him to finish off in the final phase of the fight.

Fighting Games

- The Caribbean
(an RPG made in the Warcraft III editor): One boss fight is against a Monster Whale (actually a Mosasaurus) that swallows the ship as soon as it gets close.

- Diablo III: Downplayed with the Sin Hearts (the Heart of the Damned and the Heart of the Cursed), which the Nephalem has to destroy in order to shut down Azmodan's invasion in the third act.

- The Elder Scrolls III: Morrowind: The end boss is actually two: the invulnerable Big Bad Dagoth Ur who relentlessly attacks you, and an Artifact of Doom called the Heart of Lorkhan, the heart of a dead god, which you have to destroy to kill the Big Bad (since it acts as an Immortality Inducer for him).
- Grandia II: While the Heart of Valmar has a distinct effect on one very plot-important character, the heroes never get a chance to take it on as an arc boss like the other body parts. Instead, the Heart is fought inside Valmar as the end of a Boss Rush sequence just before you face off against the Core of Valmar.
- Paper Mario 64: Inverted with Tubba Blubba, who is invincible until you find and defeat his heart which is hidden elsewhere, forcing it to return to his body. Tubba himself then proves to be weaker than a normal enemy in the fight that follows.

The boss battle itself has said Nexus spawn lots of enemies of all classes barring Harvesters and sub-bosses, and the idea is to first deplete the regenerating shield protecting the Nexus and then damage it in the short time between the shield's destruction and its regeneration. Rinse and repeat until it explodes.
- Shadow Warrior 3: The Final Boss of the game is the Evildoing Dragon's own heart. When protagonist Lo Wang enters the dragon after every single other plan failed, he travels through the innards of the Dragon until he reaches the heart. Said heart is a tentacle-based Stationary Boss flunkied by several Youkai of different classes, and the boss battle is a typical "shoot the weak points to hit the health bar" battle. The heart also attacks alongside the Youkai. When the battle is over, a cutscene plays with Wang stabbing Hoji's mask with his Katana straight in the Dragon's heart, splitting it in two and ending the threat for good.

It is unprotected though, with its only "protection" being its container, presumably because of What Could Possibly Go Wrong? mentality.
