The Binding of Isaac Wiki

Embryos are one of the weakest monsters and the Blastocyst's last stage type.

Behavior[]

Embryos hop around aimlessly, but can still deal contact damage. This enemy can spawn on any floor and is usually met in a room with a Blood Donation Machine.

Champion VariantWrath of the Lamb DLC[]

Eternal Embryo in its full-size shoots large rings of blood shots every time it jumps. Upon taking enough damage, it splits into 4 smaller Eternal Embryos that shoot less blood shots. Smaller Eternal Embryos, however, can only split into 2 even smaller ones, and they no longer shoot blood shots if they are smaller than half-sized ones.

A full-sized Eternal Embryo can split 4 times, for a total of 32 extremely small Eternal Embryos.

Trivia[]

  • An embryo is a multicellular diploid eukaryote in an early stage of embryogenesis, or development.
  • Embryos bear a strong resemblance to Spewer, the character of the game Spewer which was also created by Edmund McMillen.
  • Embryos use the same death sounds as Gooballs from the game World of Goo. The same applies to Babies, Angelic Babies, and Freds.
  • Embryos have a boss health meter due to them being the final stage of Blastocyst and therefore the game counts them as a boss, as confirmed by Edmund McMillen on his Tumblr.[1]
