The Forgotten It's complicated
Added in Afterbirth †

The Forgotten is a secret character added in Booster Pack #5 that resembles a Bony. He cannot fire regular tears, and instead has a bone club that can be swung as a melee weapon or charged to be thrown.

The Forgotten cannot acquire regular heart containers. Any regular heart containers acquired will be turned into bone hearts, and any soul or black hearts will be given to The Soul. The Forgotten and The Soul share a health bar, so each form has a maximum of 6 hearts instead of the regular 12.

The Soul

Pressing the swap key (CTRL on PC / R2 on PS4 / RT on Xbox / ZR on Switch) will switch control to The Soul, a blue ghost chained to The Forgotten who fires spectral tears and flies.

While controlling The Soul, The Forgotten cannot take damage, blocks all normal shots that touch it, and attracts shots in a small <1 tile radius. If The Soul dies, the run will end.


  • The Forgotten's bone club deals 3× his damage when swung and 1.5× his damage when thrown.
  • The Forgotten's bone club passes through walls, obstacles, and enemies.
  • The Forgotten cannot take deals with the Devil as he only has bone hearts, but The Soul can with its soul hearts. If a deal would kill The Soul, quickly switching to The Forgotten will keep him alive.
    • If The Soul has no Hearts, switching to The Soul is disabled until another Soul or Black Heart is acquired.
    • Losing red hearts inside bone heart containers does not count as red heart damage for devil deal chances, but breaking bone heart containers does.
    • Added in Repentance The Forgotten can take devil deals at the cost of Bone Hearts, equally to normal Red Hearts.
      • Added in Repentance As such, it is possible to softlock the game by taking a deal that would kill The Forgotten and switching to The Soul.
        • Added in Repentance It may be possible to avoid this softlock with Added in RepentanceBirthright Birthright, since going through doorways as The Soul doesn't reset control to The Forgotten.
  • The Forgotten's melee attack can collect pickups and open chests.
  • Crow Heart Crow Heart prevents The Forgotten from losing bone heart containers as long as it still has red health.
  • The shot speed and tear height stats have no effect on The Forgotten's melee attack or bone toss.
  • The range stat increases how far away from The Forgotten the melee attack's arcs appear. It doesn't affect the bone toss.
  • Items that increase character size increase the range of the melee attack. Items that decrease character size have no effect on the range of the melee attack.
  • To switch between two pills/cards, press the swap key twice quickly.
  • Picking up health upgrades as The Soul will convert them into soul hearts, just like ??? ???. It's generally advisable to pick up health as The Forgotten, since bone hearts are much rarer.
  • Removed in RepentanceUnidentified pills are more safely consumed in Soul form, as a Hematemesis pill can be very detrimental for The Forgotten but has no negative effect when consumed as The Soul.
    • Health Down pills are converted to Health Up for both forms, but the empty bone heart gained may be risky for retaining Devil Room chances.
    • Added in Repentance Health Down pills aren't converted to Health Up anymore.
  • Added in Repentance With Added in RepentanceBirthright Birthright, the player can leave The Forgotten's body in a room and move to a different room with The Soul. When the player switches control back to The Forgotten, The Soul instantly teleports back to the other room where the body was left in.
    • Added in Repentance This makes it possible to enter and leave Curse Rooms entirely without taking damage - leave the body outside of the Curse Room, go into the Curse Room as The Soul, then switch control to leave.
    • Added in Repentance This behavior can possibly complicate things at the Rotgut fight - after the player defeats the third phase of the boss as The Soul and is ejected back into the boss room, switching control back to The Forgotten will teleport the player back into the third phase of the fight, with that phase of the boss having respawned.
  • In Co-Op mode, if The Forgotten dies, their ghost baby will wield the bone club instead of firing tears.

Unlocking The Forgotten

The Lamb must have been defeated previously before The Forgotten can be unlocked, and unlocking The Forgotten can be done in both Normal and Hard difficulty. Having The Negative The Negative unlocked is recommended.

  1. First, start a new unseeded run as any character. Defeat the first floor's boss within 1 minute. If done correctly, Mom will yell and the sound of running footsteps will play, then a large shadow of a shovel handle will loom over the floor of the starting room. Bombing anywhere in the starting room will spawn the Broken Shovel Broken Shovel. Initially the shovel piece behaves like a pickup, laying on the floor, and turns into an active collectible only when touched for the first time.
    • Holding the Broken Shovel will cause Mom to continually try to stomp Isaac. Using the Broken Shovel will stop the stomping for the current room, or the current wave of a multi-wave room such as the Boss Rush.
      • The stomps won't happen in the Mom fight.
      • Removed in Repentance Stomps count as explosions, soPyromaniac Pyromaniac orHost Hat Host Hat provide immunity to them.
      • Stomps break rocks and damage enemies. If the player has Gnawed Leaf Gnawed Leaf and a lot of patience, the stomps will eventually clear rooms.
      • Stomps will open secret rooms.
    • On XL floors, only the last boss must be defeated. The Emperor Card allows the first boss to be skipped.
    • Once the Broken Shovel is picked up, it must not be replaced by another active item. If it is on an item pedestal when Isaac leaves the room, it will disappear.
    • If playing in Co-op, Mom will only target the player with the Broken Shovel. If this character dies, the stomps will stop, and if they are resurrected, the stomps continue. If you beat Mom while the character holding the Broken Shovel is dead, the Boss Rush door is closed and the Womb entrance is sealed. If you have a card/pill/item that allows for teleportation, returning to Boss Room fixes this bug.
  2. Next, clear Boss Rush. This will grant the second piece of the Broken Shovel Broken Shovel, completing Mom's Shovel Mom's Shovel.
    • The Broken Shovel must be held when the boss rush is beaten. Otherwise, only a normal boss rush completion item will drop.
    • After defeating Mom, if it is unlocked onlyThe Negative The Negative will spawn, otherwise a standard boss item will spawn.
    • If The Negative The Negative is not unlocked you must use a Sacrifice Room to proceed to Dark Room Dark Room, you are not guaranteed to be able to do this on every run.
    • The normal 20-minute time limit to reach Boss Rush does not apply. The hole to after Mom will be sealed until the Boss Rush is completed.
    • After Mom's Shovel is acquired, Mom's feet will stop attempting to stomp Isaac.
  3. Finally, a single Grave Room with a dirt patch in its center will appear in the Dark Room Dark Room. Using Mom's Shovel while standing on the dirt patch unlocks The Forgotten.
    • If the Grave Room is exited before the soul reaches the top of the screen, The Forgotten may not unlock.
    • Holding Mom's Shovel prevents the beam of light to the Cathedral from appearing, forcing Isaac into the trapdoor to Sheol Sheol.
    • If stuck, confused, or frustrated, check theBroken Shovel Broken Shovel page for tips and help.
