Isaac's Mom is the boss found in The Depths II and is the final boss for the game's prologue. She is told to sacrifice her son by the voice of God.

Behavior[edit | edit source]

Mom's fight takes place in the entirety of the room. Four Boss Room doors will emerge on all four sides of the room, and Mom can attack from any of these doors. She can stomp on Isaac, which is telegraphed by a growing shadow and her screaming. All of her attacks will deal a full heart of damage. She can only be hurt by hitting her directly when she exposes her foot, eye, flesh, or hand.

Standing too close to the doors will result in Mom striking with her hand. If the player isn't in reach and she isn't using her foot stomp attack, a piece of flesh will bulge from the doors and spawn various enemies. Occasionally, she may stick her eye out of the door, which is harmless and vulnerable to being attacked by Isaac.

Mom's stomp attack can damage nearby enemies and destroy obstacles, but the foot itself does no contact damage.

The Bible[edit | edit source]

Champion Variants[edit | edit source]

  • Blue: This variant summons more often and only summons various types of enemies added in the Wrath of The Lamb expansion for the original game, including Big Spiders, Trites, Buttlickers, and Keepers.
  • Red: This variant does not summon at all, and instead constantly uses her foot stomp. Her eyes can shoot three blood shots at the player when they emerge and she uses her hand much more often.

Notes[edit | edit source]

  • Using The High Priestess card during the fight with Mom will result in Isaac being stomped instead of the enemy with the highest health.
  • Mom's stomp attack counts as a bomb; this means Isaac can be immune to it with Pyromaniac or DLC Indicator.pngHost Hat.
    • With Pyromaniac, Isaac can be healed when stomped.
    • Red Mom is nearly impossible to lose against with Pyromaniac or DLC Indicator.pngHost Hat.
  • Mom cannot damage herself with her stomp attack.
  • Midas' Touch causes Mom's foot to be turned into gold before it lands, giving the player ample time to move out of the way and place bombs or otherwise.
  • After Mom's foot touches the ground, it is safe to touch no matter what; as opposed to dealing touch damage, it is purely explosive.
  • DLC Indicator.png Mom can now spawn some of the new DLC monsters such as Dank Globins due to the Monster Variants of the original enemies.
  • The Polaroid is always to the left and The Negative is always to the right.

Unlockable Achievements[edit | edit source]

  • The Womb The Womb - Defeat Mom for the 1st time.

  • Purist Purist - Defeat Mom for the first time.
  • SPEED! DLC Indicator.png SPEED! - Defeat Mom for the 1st time.

Gallery[edit | edit source]

Trivia[edit | edit source]

  • Mom is the only boss in the game to have a unique design for her name in the Versus screen.
  • In the original game, Mom's leg dealt a full heart of contact damage.
