Chub is a boss that can appear in The Caves The Caves and the Added in Afterbirth Flooded Caves Flooded Caves.

Behavior[edit | edit source]

Chub moves randomly around the room in cardinal directions and can perform the following attacks:

  • Charges at Isaac whenever he lines up with one of her cardinal directions.
    • Chub eats any Bombs dropped in her path; stunning her for a moment before dealing considerable damage.
    • This attack does a full heart of damage under normal conditions.
  • Spawns a Charger.
    • Chub's charge attack can damage and kill any Chargers.

Champion Versions Needs to be unlocked[edit | edit source]

  • Cyan: 15% larger and slower than normal, with 25% more HP (437.5). Spawns Black-coloured Boils instead of Chargers. Despite the different color, they behave exactly like normal Boils.
  • Orange: 15% smaller and faster than normal, with 15% less HP (297.5). Spawns Spitties instead of Chargers.

Gallery[edit | edit source]

Notes[edit | edit source]

  • Chub is often paired with Chargers in the boss room.
  • When using 15►Dr. Fetus Dr. Fetus' bomb combined with a shot type that passes through enemies, Chub will not eat the bomb.
  • Each segment of Chub can be individually damaged, so a single piercing tear could hit Chub multiple times.
    • Added in Repentance Piercing shots no longer damage segmented enemies multiple times per attack.
  • Chub will eat Troll Bombs (such as those set by other bosses) just like bombs dropped by Isaac.
  • 15►Best Friend Best Friend can damage Chub if eaten, similar to a bomb.

Trivia[edit | edit source]

  • Chub appeared in the original Binding of Isaac.
    • Sometimes, in the original game, Chub would spawn with only two segments, preventing her from spawning anything.
  • Carrion Queen is the posthumous version of her, and C.H.A.D. is the alternate version.
  • She is the boss version of the Chargers.
  • Chub is one of three bosses to have its posthumous version in the same chapter, the other cases being Gemini having Blighted Ovum in chapter 1 and Polycephalus having Added in Afterbirth The Stain in chapter 2.
    • However, Chub doesn't appear in the same environment as Carrion Queen, who appears in The Catacombs The Catacombs while Chub appears in The Caves and the Added in Afterbirth Flooded Caves.
  • Chub is confirmed to be female.
  • Chub may also be a reference to the Dodongos from The Legend of Zelda, which Link had to toss bombs into their mouths to kill. This is supported by the Rules Card's display of "CHUB DISLIKES SMOKE", a reference to "DODONGO DISLIKES SMOKE" from the original Legend of Zelda.
  • Added in Afterbirth † The Matriarch is a boss from Booster Pack #5 that is simultaneously based of Chub, Fistula, and Fistuloid. When at low HP, she will split into Chub.
    • Unlike the usual pattern, if the Chub from The Matriarch eats a bomb, she'll spit it back at the player.
  • Chub is one of the four bosses that can be spawned by It Lives, the other three being Fistula (as of Repentance), Polycephalus and Teratoma.
  • Added in Afterbirth † Prior to Booster Pack #5, Chub could spawn Drowned Chargers if she was fought in the Added in Afterbirth Flooded Caves. This also applies to Added in Afterbirth The Stain.

Bugs[edit | edit source]
