Binding of Isaac: Rebirth Wiki

Chub is a boss that can appear in the CavesCaves and the (except in Rebirth)Flooded CavesFlooded Caves.

Behavior[ | ]

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

  • Charges at Isaac whenever she lines up with one of her cardinal directions.
    • Chub eats any BombBombs dropped in her path; stunning her for a moment before dealing considerable damage.
  • Spawns a 1-2 ChargerCharger up to a maximum of 5 (occasionally 6 if she spawns 2 while there are 4 alive).
    • Chub's charge attack can damage and kill any Chargers.

Chub deals a whole heart of contact damage.

Champion Versions Needs to be unlocked[ | ]

Blue: 15% larger and slower than normal, with 25% more HP (437.5). Spawns (except in Repentance)Black/(in Repentance)Orange-coloured BoilBoils instead of Chargers. Despite the different color, they behave exactly like normal Boils. (Note that this actually looks green in-game, but internally it is labeled as blue. This is because yellow mixes with blue to cause green.)
Orange: 15% smaller and faster than normal, with 15% less HP (297.5). Spawns SpittySpitties instead of Chargers.

Notes[ | ]

  • Chub is often paired with Chargers in the boss room.
  • When using Collectible Dr. Fetus iconDr. 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.
    • (in Repentance) Piercing shots no longer damage segmented enemies multiple times per attack.
  • Chub will eat Troll BombTroll Bombs (such as those set by other bosses) just like bombs dropped by Isaac.
  • Collectible Best Friend iconBest Friend can damage Chub if eaten, similar to a bomb.
  • (in Repentance)Collectible Meat Cleaver iconMeat Cleaver can instantly kill Chub.
  • Chub can spawn without the last segment.

Trivia[ | ]

  • 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. This can also happen in Repentance.
  • Boss Carrion Queen ingameCarrion Queen is the posthumous version of her, and Boss C.H.A.D. ingameC.H.A.D. is the alternate version.
  • She is the boss version of the Chargers.
  • Chub is one of four bosses to have its posthumous version in the same chapter, the other cases being Boss Gemini ingameGemini having Boss Blighted Ovum ingameBlighted Ovum in chapter 1, (except in Rebirth) Boss Polycephalus ingamePolycephalus having Boss The Stain ingameThe Stain in chapter 2 (in Repentance) and the Boss Tuff Twins ingameTuff Twins having Boss The Shell ingameThe Shell in Chapter 2.5.
    • However, Chub doesn't appear in the same environment as Carrion Queen, who appears in the CatacombsCatacombs while Chub appears in The Caves and the (except in Rebirth) Flooded Caves.
  • Chub is female.[1]
  • 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.
  • (in Afterbirth † and Repentance) Boss The Matriarch ingameThe Matriarch is a boss from Booster Pack #5 that is simultaneously based on Chub, Boss Fistula ingameFistula, and FistuloidFistuloid. When at low HP, she will split into a medium-sized Fistula, two small Fistulas, a Fistuloid and 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 Boss It Lives ingameIt Lives, the other three being Fistula (as of Repentance), Polycephalus and Boss Teratoma ingameTeratoma.
  • (in Afterbirth † and Repentance) Prior to Booster Pack #5, Chub could spawn Drowned ChargerDrowned Chargers if she was fought in the Flooded CavesFlooded Caves. This also applies to Boss The Stain ingameThe Stain.
