First page of the bestiary

The bestiary is a new addition to The Binding of Isaac: Afterbirth † that is accessible through the "Stats" menu. The Bestiary shows information and statistics on all encountered monsters and bosses except for some alternate forms of some enemies.

It shows the number of times an enemy has been encountered, how much health it has, how much damage it has done to Isaac, how many times it's been killed, and how many times it has killed Isaac.

Because Repentance added a lot of new enemies, the whole page layout was reworked, requiring this page to be separate from the Afterbirth † Bestiary (ab+).


  • The order of the monsters starts with Rebirth enemies, then Afterbirth enemies, then Afterbirth †, and finally Repentance enemies.
  • Encountering a boss while fighting Delirium does not count towards the bestiary.
  • Seeded and challenge runs will affect bestiary entries, including whether an enemy has been found at least once or not, meaning that regardless of whether achievements are disabled or not, bestiary entries will still be updated.
    • This also means that enemies spawned using the developer console will be counted as well.
  • While fighting Hush, the Blue Boil will count as an encounter but the Blue Gaper will not. A Blue Gaper must be found on its own to be marked as an encounter.


These are the monsters on each of the bestiary's pages.

Unlockable Achievements[]

  • Sin collector
    Added in Afterbirth † Sin collector - Collect every entry in the Bestiary (bugged v190 - Mobs that don't exist in the bestiary are being counted. This allows Sin Collector to be unlocked without a complete bestiary).



Bug Bug! The Bestiary is bugged with bosses that have multiple parts (such as Larry Jr., Pin, The Hollow, and so forth).
Bug Bug! The Sin Collector achievement can be obtained without a full Bestiary. It requires about 5-8 entries less than what is actually featured.
