C.H.A.D.

C.H.A.D. is a boss that can appear in the Caves and the Flooded Caves.

• C.H.A.D is much less common than his counterpart, spawning only 1/4th as often.
• C.H.A.D can spawn alongside 2 Boils or 2 Red Boom Flies.
• Each segment of C.H.A.D. can be individually damaged, so a single piercing tear could hit C.H.A.D. multiple times.
• Piercing shots no longer damage segmented enemies multiple times per attack.

• C.H.A.D. appeared in the original The Binding of Isaac.
• He is a rare alternative to Chub.
• C.H.A.D. is a cameo from Super Meat Boy, a game by Edmund McMillen.
• In Super Meat Boy, he is the boss of Chapter 2: The Hospital.
• When defeated in Super Meat Boy, C.H.A.D. would shrink to a smaller version of himself. Him getting smaller during the fight in Rebirth and the item Little C.H.A.D. are allusions to this.
• The name C.H.A.D. is a reference to the 1984 horror film C.H.U.D., confirmed by Edmund.
• Despite C.H.A.D. normally being speculated to stand for "Cute, Huge and Deadly," Edmund McMillen had confirmed that it doesn't stand for that phrase.
• When asked what it does stand for, Edmund jokingly replied that he can't legally say.
• C.H.A.D.'s secret for unlocking him says "In the Depths" even though he is found in The Caves.
