Dr. Fetus

{{:{{{1}}} | {{{1}}} | {{{2}}} }}

**Dr. Fetus** is a Special unlockable passive item.

## Effects

* Tears are replaced with bombs that explode approximately one second after being fired.
	+ File:NoDLC Indicator.png Each bomb deals 3 times the character's normal tear damage.
	+ File: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.
	+ File:DLC Indicator.png In Afterbirth, many more synergies have been added.
* Dr. Fetus is one of the items that directly affect tear delay.

## Synergies

* 20/20: Shoots 2 bombs instead of 1 without decreased fire rate.
* Blood Clot: Bonus damage applies on every shot. Also turns bombs red.
* Bob's Bladder: Creep is left along the path that the bomb travels.
* Bobby-Bomb: Bombs slowly home in on enemies.
* File:DLC Indicator.png Bomber Boy: Bombs explode in a large cross pattern.
* Butt Bombs: Bombs confuse enemies, and deal minor damage to the entire room, regardless of impact.
* Chocolate Milk: Slightly increases fire rate; no effect on damage.
* File:DLC Indicator.png Cricket's Body: Bombs split into 4 tiny bombs.
* Fire Mind: Bombs leave behind a fire like Hot Bombs.
* File:DLC Indicator.png 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.
* File:DLC Indicator.png 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.
* Holy Light: No effect.
* File:DLC Indicator.png Host Hat: The item grants invincibility from explosions, preventing self-damage.
* File:DLC Indicator.png Hot Bombs: Bombs leave behind fire that damages enemies on contact after exploding.
* Homing Tears: Bombs home in on enemies.
* The Inner Eye: Shoots 3 bombs instead of 1, but decreases fire rate.
* 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 renders Isaac no longer immune to his own shots, also they will explode as soon as you shoot.
* The Ludovico Technique: Bomb can be controlled before exploding, similar to Epic Fetus.
* Monstro's Lung: Same effect as 20/20, except retains fire rate.
	+ File:DLC Indicator.png Shoots 6 bombs. The bombs detonate simultaneously.
* Mr. Mega: Significantly increases damage.
* Mutant Spider: Shoots 4 bombs instead of 1, but decreases fire rate
* Poison Tears: Poison effects will give bombs a flat +50 damage. This is guaranteed by Ipecac, Bob's Curse, and Scorpio, and can also proc from The Common Cold or Pinky Eye.
* Ouija Board: Bombs will become spectral and pass through objects just like spectral tears do.
* Polyphemus: Bombs increase in size and do increased damage.
	+ File:DLC Indicator.png Bombs become Mr. Mega bombs. After they explode, they leave behind a regular-sized bomb.
* Pyromaniac: Bomb explosions heal Isaac, granting infinite health as long as Isaac has more than one heart container.
* Remote Detonator: Bombs can be detonated early, making it easier to hit moving enemies.
* File:DLC Indicator.png Sad Bombs: Fires tears as normally placed Sad Bombs would. If this synergy is combined with Ipecac, the tears from the bomb become explosive, which Isaac is not immune to. Note: tears fired from previous Dr. Fetus bombs can collide with other Dr. Fetus bombs (can be negated with spectral tears).
* File:DLC Indicator.png Scatter Bombs: Each bomb splits into 2-4 small bombs, each of which is also affected by Isaac's bomb modifiers.
* File:DLC Indicator.png Serpent's Kiss: Causes your bombs to randomly be transformed into poison bombs.
* File:DLC Indicator.png Spoon Bender: The bombs are purple and act as if Isaac had Bobby-Bomb.
* File:DLC Indicator.png Tech X: A laser circle forms around the bomb and kills occasionally drop black hearts.
* File:DLC Indicator.pngThe Wiz: Shoots two bombs diagonally.
