Dr. Fetus is a Special unlockable passive item.

Effects

  • Tears are replaced with bombs that explode approximately one second after being fired.
    • NoDLC Indicator.png Each bomb deals 3 times the character's normal tear damage.
    • DLC Indicator.png Each bomb deals 5 times the character's normal tear damage plus a flat 30 damage. The flat 30 is not affected by damage multipliers.

Notes

  • Dr. Fetus overrides multiple tear effect items but benefit from some (but not all) bomb-enhancing effects like Mr. Mega Mr. Mega .
    • DLC Indicator.png In Afterbirth, many more synergies have been added.
  • With Dr. Fetus, the range and shot speed stats both affect the velocity at which the bombs are fired out. Delay before explosion is not affected by either.
  • Dr. Fetus is one of the items that directly affect tear delay.

Synergies

  • 20/20 20/20 : Shoots 2 bombs instead of 1 without decreased fire rate.
  • Blood Clot Blood Clot : Bonus damage applies on every shot. Also turns bombs red.
  • DLC Indicator.png Bob's Bladder Bob's Bladder : Creep is left along the path that the bomb travels.
  • Bobby-Bomb Bobby-Bomb : Bombs slowly home in on enemies.
  • DLC Indicator.png Bomber Boy Bomber Boy : Bombs explode in a large cross pattern.
  • Butt Bombs Butt Bombs : Bombs confuse enemies, and deal minor damage to the entire room, regardless of impact.
  • Chocolate Milk Chocolate Milk : Slightly increases fire rate; no effect on damage.
  • DLC Indicator.png Cricket's Body Cricket's Body : Bombs split outwards into 4 tiny bombs, which detonate almost immediately.
  • Fire Mind Fire Mind : Bombs leave behind a fire like Hot Bombs Hot Bombs .
  • DLC Indicator.png Fruit Cake Fruit Cake : The random tear effects are instead applied on bomb explosion. Some of the normal effects are replaced with bomb-specific effects, like Glitter Bombs Glitter Bombs .
  • DLC Indicator.png Glitter Bombs Glitter Bombs : Each bomb fired has a chance of dropping a random consumable or trinket (rarer) after exploding. This synergy theoretically gives you an infinite supply of consumables.

  • DLC Indicator.png Host Hat Host Hat : The item grants invincibility from explosions, preventing self-damage.
  • DLC Indicator.png Hot Bombs Hot Bombs : Bombs leave behind fire that damages enemies on contact after exploding.

  • The Inner Eye The Inner Eye : Shoots 3 bombs instead of 1, but decreases fire rate.
  • Ipecac Ipecac : Isaac is immune to his own bomb shots (not explosives or placed bombs) and damage is massively increased, as the +40 damage from Ipecac is run through the damage multiplier of Dr. Fetus. Shots will also explode immediately on impact with enemies, rocks or walls. If this synergy is mixed with Sad Bomb, Isaac will remain immune to the bomb itself, but not to the explosive tears. Mixing this synergy with Monstro's Lung Monstro's Lung renders Isaac no longer immune to his own shots, also they will explode as soon as you shoot.

  • Monstro's Lung Monstro's Lung : Same effect as 20/20 20/20 , except retains fire rate.

  • Remote Detonator Remote Detonator : Bombs can be detonated early, making it easier to hit moving enemies.
