Trivia[ | ]

  • In the Hebrew Bible, the name Abaddon is used as a reference to a bottomless pit, often appearing alongside the place of the dead (which is known as Sheol), meaning the land of the dead. The actual Hebrew word Abaddon (אבדון - pronounced avadon) means "doom".
  • Abaddon is the Hebrew equivalent of Apollyon.
  • In the New Testament's Book of Revelation, an angel called Abaddon is written as the king of an army of locusts; his name is first transcribed in Greek (Revelation 9:11 – "whose name in Hebrew Abaddon").
  • Abaddon also shares its name with a level from Edmund's previous game Super Meat Boy.

Bugs[ | ]

Bug Bug! (in Rebirth and Afterbirth) If Character Keeper iconKeeper picks up Abaddon, it will remove all of his Coin Hearts but will not kill him until he picks up an item.
(in Afterbirth †) This still applies if Abaddon is acquired via the Debug Console, but not if the item is picked up normally.
