Chub is a boss found in The Caves and the Flooded Caves. Chub is a large maggot which will charge Isaac as well as spawn chargers to aid her.

Behavior[edit | edit source]

Chub charges at Isaac whenever in line of sight, dealing damage upon hit.
- Even after hitting Isaac, Chub will continue to charge until she hits a wall.
If Isaac drops a bomb in front of Chub when she's charging, she will eat the bomb, freezing in place with a terrified face (the same face in the death animation) and being dealt damage to after a small delay.
Chub will occasionally spawn Chargers, which will chase Isaac whenever in line of sight.

Orange: Smaller and faster than normal. Spawns Spitties instead of Chargers.
Blue: Larger and slower than normal. Spawns black Boils instead of Chargers.

Chub is often paired with Chargers in the boss room.
- She can also be paired with Drowned Chargers, even if she isn't in the Flooded Caves.
Sometimes, Chub can spawn with only two segments, preventing her from spawning anything.
When using 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 possibly hit Chub multiple times.
Chub will eat troll bombs (such as those set by other bosses) just like bombs dropped by Isaac.
If Chub spawns in the Flooded Caves, she can spawn Drowned Chargers.
Best Friend can damage Chub if eaten, similar to a bomb.

Carrion Queen is the posthumous version of her, and C.H.A.D. is the alternate version.
Chub is one of three bosses to have its posthumus version in the same chapter, the other cases being Gemini having Blighted Ovum in Chapter 1 and Polycephalus having The Stain in Chapter 2.
- However, Chub doesn't appear in the same environment as Carrion Queen, who appears in the Catacombs while Chub appears in The Caves and the Flooded Caves.
Chub appeared in the original Binding of Isaac.
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.
If you look closely at the death animation, you could see that Chub is crying bloody tears.
The Matriarch is a boss from Booster Pack #5 that is simultaneously based of Chub herself, 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 three bosses that can be spawned by It Lives, the other two being Polycephalus and Teratoma.

Bug! If Chub is killed while frozen by Mom's Contacts, only the part to receive the last shot will die.
