The Big Airship of Doom, or simply known as BAD, is a type of MOAB-Class Bloon in Bloons TD 6 and the strongest non-Boss Bloon in the game. In standard gameplay, it first appears on Round 100 or Round 99 in Alternate Bloons Rounds. BADs have the same speed and size as ZOMGs. It is immune to all forms of blowback, knockback, and slowing (including being stunned). When popped, it releases two ZOMGs and three DDTs.
Although the BAD normally has 55,760 RBE (98,360 when Fortified), the health of all MOAB-Class Bloons increases with each round after round 81, so its actual RBE on round 100 is 67,200 (133,280 when Fortified, as seen in Alternate Bloons Rounds).
