Notes[]

  • Just like Mom and Mom's Heart, using The Bible The Bible or Added in RepentanceXV - The Devil? XV - The Devil? against It Lives will kill it instantly.
  • Added in Afterbirth Isaac can encounter It Lives in the nightmare boss wave of chapter 4 in Greed/Greedier mode even if it has not been unlocked.

Trivia[]

  • It Lives! appeared in the original The Binding of Isaac.
  • The music that plays during this fight is titled Ventricide.[1] Ventricide is a portmanteau formed from the word ventricle (chamber 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.
    • Ventricide could also be a junction of the prefix ventr-, which could denote "belly", "stomach", or "womb" with the suffix -cide.
  • It Lives, according to the developers, takes the shape of what Isaac looked like as a fetus.
  • According to Edmund McMillen, It Lives supposedly represents Isaac wishing that he were never born.
  • It Lives makes the same sounds as Mom's Heart.
    • Like Mom's Heart, if Isaac takes damage from It Lives' Brimstone Brimstone attack, Mom's laugh can be heard.
  • Despite being a major boss, It Lives doesn't belong to any Ending, instead, it opens up entrances to both Sheol Sheol and the Cathedral Cathedral, as well as Added in Afterbirth ??? ??? if beaten in under 30 minutes.
  • The unlock note for It Lives states "Your futures past awaits.", referencing Time Fcuk, another game by Edmund Mcmillen.
  • Removed in Repentance During the versus screen, It Lives' enemy/boss-spawning sound can be heard. It Lives is one of seven bosses that can be heard during the versus screen, the other six being Added in Afterbirth The Stain, Added in Afterbirth The Forsaken, Added in Afterbirth † Big Horn, Mom, Removed in Repentance Mom's Heart and Added in Repentance Mother.

Bugs[]

Bug Bug! Removed in Afterbirth † Sometimes, if the boss intro is skipped, the game will not teleport Isaac into the center of the bottom of the room, resulting in immediate contact damage with one of the Eyes or It Lives, depending on the direction of the room's entrance.
