Gaper

Gapers walk towards Isaac by the most direct route possible. They will actively path around obstacles and other enemies that block their path to Isaac. Upon death, they will usually transform into a Pacer or with a slightly lower chance a Gusher.

• When Head of the Keeper is picked up as Keeper, he will look similar to the Greed Gaper.
• The appearance of Cyclopias is reminiscent of the fatal birth defect of the same name, which is characterized by the failure of the embryonic prosencephalon to properly divide the orbit of the eyes into two cavities.
• A Stoney makes the same sound as a Large Champion Gaper.
• Frowning Gapers and Nulls don't make noises until they open their eyes.
• Greed Gapers are also known as Greedlings, a name given by a card of it from The Binding of Isaac: Four Souls, although it's seldom referred to as a "Greedling" by players.
• Gapers have among the most variations of any 'family' of monster.
• Blurbs spawned outside of Downpour will be skin-toned.
• Wraiths spawned in rooms without water will appear translucent.
• Blurbs, Deep Gapers, Wraiths, Rotten Gapers, and Twitchies originate from the Antibirth mod. In Antibirth, Deep Gapers were referred to as Tidal Gapers.
• Despite being a hybrid with a Trite, Twitchies aren't affected by Bursting Sack due to being categorized as a Gaper variant.
• 34 Dead Isaacs are specifically spawned in Mother's attack, referencing the 34 playable characters, implying that they are all dead. This makes sense, as all characters really are Isaac himself, whom we see suffocating in a chest in Ending 20.
• A Frowning Gaper figure can be seen in the screenshot for the starter house in Mewgenics, another game from Edmund McMillen.
