Behavior[edit | edit source]
Phase 1[edit | edit source]
The Frail in its first phase has 100 HP like Pin and behaves identically; burrows into the ground before performing the following attacks:
- Jumps out of the ground towards Isaac and burrowing back into the ground at the end of the jump.
- Occasionally fires 4 projectiles diagonally from the last section of its body when exiting the ground and/or when burrowing back into the ground.
- Partially emerges out of the ground to fire a red
Ipecac shot at Isaac before returning underground.
- After doing this attack, The Frail will always jump out of the same spot it entered.
Phase 2[edit | edit source]
Upon its HP being depleted, The Frail's appearance becomes skeletal. It now has 200 HP and performs the following attacks:
- Jumps out of the ground towards Isaac, firing 4 diagonal projectiles from the last section of its body that each split into 4 more projectiles in either cardinal or diagonal directions. Burrows back into the ground at the end of the jump.
- Partially emerges head-first and:
- Fires a
Brimstone laser at Isaac rotating to follow his movements.
- Fires a quick, non-moving Brimstone laser at Isaac 2 times before stopping.
- After performing any of these attacks, The Frail will always jump out of the same spot it entered.
- Fires a
- Partially emerges tail-first and fires a burst of white projectiles in all directions which leave small puddles of slowing White Creep where they land.
- After performing this attack, The Frail will always jump out of the same spot it entered.

Trivia[edit | edit source]
- It is the posthumous version of Pin.
- 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.
- The main body of The Frail's battle sprite is heavily based on Larry Jr.'s battle sprite.
- The Black Champion's behavior of starting from the second phase might be a bug since this version of the boss is set to have 30% more HP (260) in its first phase. Spawning the black champion via the Debug Console displays a glimpse of the boss in its first phase, before being instantly replaced with the second phase, ignoring the amount of HP set in the game files.
The Frail can be found in
The Void, even before being unlocked.
- It is the boss version of the
Pasties.
