	Something wicked this way comes!

The Frail is a boss added in Afterbirth that can appear in all environments of Chapter 2. It is the posthumous version of Pin.

Behavior[edit | edit source]

In the first phase, The Frail's attacks are identical to Pin’s. However, the Frail moves faster. Upon running out of health, The Frail becomes skeletal, beginning the second phase.
In the second phase, The Frail has three attacks:
- Jumps out of the ground at Isaac, firing four tears from the last section of its body that each split into four more tears that either travel diagonally or straight.
- Sticks its head out of the ground, then fires a rotating Brimstone
  Tears are replaced by a laser beam that pierces through all enemies and obstacles in its path and deals high damage. Can only be fired after a short charge-up period.
  laser at Isaac.
  - Alternatively he will turn to Isaac to fire a quick, non-moving Brimstone laser 2 times before stopping.
- Sticks its tail out of the ground, then fires a burst of spectral tears in all directions which leave small puddles of white slowing Creep where they land.

Despite The Frail being an invertebrate, or an animal lacking a skeleton of bones, its second phase is skeletal.
The definition of the word frail is weak and delicate, which explains its rotting body and depressed look in The Frail's first phase.

Bug!

If The Frail is under the effects of

in mid-air, its jump will be stopped and it will fall.
