The Big One is a MilitaryMonkeycard in Bloons Card Storm. Instead of its attacks being controlled by the player, it automatically attacks a random Bloon on the opponent's side at the end of the player's turn. If given additional Ammo, it will use Ammo as many times as it can at the end of a turn. Only one copy of The Big One can be in the Collection.
The card artwork depicts a Dutch angle shot of The Big One firing a violent blast, causing a shockwave. The operator is blocking their ears behind a rock. Clouds surround the edges of the blast. The operator is absent when placed on the playing field.
The Big One is effective against bloons with high HP. Focus on getting rid of the weaker bloons, so the Big One won't have a chance to waste a shot on a weak bloon.
The Big One is one of the most space-efficient towers, dealing 160 damage per turn. Buffing it with Try this! will improve its effectiveness further, but beware a potential Return to Sender or other removal from the opponent.
Striker Jones' max passive ability also pairs well for The Big One. Ezili’s Totem also pairs well with it.
Due to its randomness, it is susceptible to Toxic Bloon's Monkey removal On Pop effect, and its high damage also makes it vulnerable to Buddy Bloon (only surpassed by, if scaled enough, some highly buffed scaling Monkeys like Spike-o-pult).
The 20 extra ATK added in Version 6.4 was added to combat the everso growing power creep of other Monkeys for the amount of downsides the Big One has.[1]
