| Mom's Heart|
Mom's Heart is the final boss in the second floor of the fourth chapter. Until It Lives is unlocked, Mom's Heart cannot be continued past unless a Devil Room or an Angel Room appears, which allow you to go to Sheol or The Cathedral, respectively. After being killed 11 times, Mom's Heart will be permanently replaced by It Lives.
Mom's Heart doesn't drop any items or pickups upon death besides hearts.
Behavior[edit | edit source]
Mom's Heart acts very differently from the original Binding of Isaac.
At the beginning of the fight, Mom's Heart will always be accompanied by two Eyes.
It has many different types of attacks, seeming to vary depending on the amount of remaining health. Many of the attacks are varying flurries of orbs that scatter across the room, which can be difficult to dodge. These orbs range from several orbs released in every direction while slowly rotating, to a fast moving line of projectiles released in four directions rotating moderately fast.
Mom's Heart also has an attack that shoots blood tears rapidly when it's ~40% lower on HP. Mom's Heart will also occasionally retreat upwards and launch blood shots diagonally forward in a spread, at which point it cannot be harmed and it will spawn various enemies. All of its attacks can hurt its own minions.
Enemies spawned by Mom's Heart are:Brimstone
|Tears are replaced by a laser beam that pierces through all enemies and obstacles in its path and deals high damage. Can only be fired after a short charge-up period.|
Upon defeat Mom's Heart fires a single ring of tears.
Notes[edit | edit source]

Trivia[edit | edit source]
- The music that plays during this fight is titled Ventricide. Ventricide is a made-up word formed from the word ventricle (one of the two larger chambers of the heart) and the suffix -cide, which denotes an act of killing. This theme is used in other tracks, such as Matricide, Hericide, and Infanticide.
- If Isaac gets hit by Mom's Heart's Brimstone attack, Mom's laugh can be heard.
- Mom's Heart can appear as a random boss in The Void, even after being replaced by It Lives in its regular chapter.
