Jacob and Esau are unlockable characters added in Antibirth. Both Jacob and Esau are controlled simultaneously, and they have separate items, trinkets, and health bars. If one of the two characters dies, the other will also die.

Both can hold active items: the active item key (SPACE) will use Jacob's item, and the card/pill use key (Q) will use Esau's item.

Both Jacob and Esau will automatically use all pills, cards, and runes they pick up.

Notes

• It is possible to take both items in double treasure rooms or boss room rewards with More Options by having Jacob and Esau each pick one up simultaneously.
• It is also possible to take 2 items from a Shop, even if you don't have the needed amount. Doing so will make your coins negative, but since the game cannot progress negative status for coins, they turn back. (Example: you have 27 coins, you get 2 items that are on full price (30 coins). Your coins will turn to -3 while still picking up the items, then they will revert back to 3)

• Key and Knife pieces are not shared between Jacob and Esau, so if the player intends to fight Mega Satan or enter the Corpse, you must pick up all the pieces with only one of the two brothers.
• Because cards, runes and pills are used the moment they are picked up, the player cannot hold onto these for future use. The card Suicide King is hard-coded not to appear while playing this character.
• It is possible to only move Jacob when you hold the drop trinket and pill button (CTRL on PC)
• Both Jacob and Esau's speed will always be the same, and both will get changes to the speed stat.
  • Libra can make the two have different speeds.
  • Picking up Goat Hoof doesn't cause different speeds, while discarding it does.
• It seems that if Money = Power is picked up by one of the characters the damage will be increased only when the coins are picked up by the character with the Money = Power item (needs further testing)
• To enter a Challenge Room or Boss Challenge Room, both Jacob and Esau must meet the health requirements.
• Infamy can trigger on both Jacob and Esau regardless of who picked it up.
• Flight can make Jacob & Esau more challenging, as only the character who picks up the flight item will be able to pass over obstacles.
• If one of the brothers has Dead Cat, when Jacob & Esau die, they will respawn with one red heart each.
• When respawning as a different character, Jacob & Esau's items will merge onto a single character.
  • This will not cause a Guppy transformation even if the brothers have three Guppy items between them.
  • The three Knife Pieces will assemble the full knife if the pieces were previously divided between the brothers.
  • If Esau had the Pony, this will grant the new character flight without taking up an active item slot.

Trivia

• Jacob & Esau are the twin sons of Isaac from the Book of Genesis. Esau is described as being "red all over" when he was born, hence why his skin is red in this game.
