Dark Dirigible Titan (D.D.T.)/Strategies

Typically, one of the best towers to counter the D.D.T. is the Spike Factory, perferably upgraded 4/2 to get the most out of it. 3/2 also does the trick, but 4/2 ensures a victory (provided that the length of the stage is at least a medium length). It's advised to place this tower near or at the end to give it time to lay down the spiked balls/mines. The 2/3 Spike Factory is also usable, but it would be better off placed close to the end of the track, with towers nearby to pop the ceramics.

Another good one is the Monkey Apprentice upgraded to 2/3 or 2/4 (Disciple/Master of Fire) placed where the path loops or curves sharply to give it massive popping power. 2 or 3 of these are needed to get rid of the D.D.T, not counting the 6 Ceramic bloon children that it spawns. A few 3/2 or 4/2 (Disciple/Master of Air, Master preferred) Monkey Apprentices can also be placed near the end to send the ceramics back to be popped, though do be wary as the ceramics can regrow and overwhelm an unprepared defense.

The Temple of the Monkey God and Monkey Village upgraded to 4/2 costs a lot, if not too much. Dart Monkeys do little damage, so they're not useful, as well as the fact that they would have to be influenced by an M.I.B or upgraded to 4/x for them to even damage the D.D.T. Dartling Guns that are upgraded to x/2, well-controlled, and sufficient in numbers can do the trick. Sniper Monkeys upgraded 4/2 are very useful, if not essential. The cost is high, but the benefits are also high.

The possibilities expand once the Radar Scanner and (optional) Monkey Intelligence Bureau are unlocked. Then, the best towers would be the fastest firing towers. One option is Super Monkeys with Plasma Vision. Ninja Monkeys upgraded 4/2 would do lots of damage, but the 2/4 allows for the sabatoge ability, cutting the speed of D.D.T.s in half, giving a better chance to destroy the D.D.T before it or its children leak. Note that the Ability works regardless of the Monkey Village, it only affects whether it can do damage to the D.D.T.

Note that attacking is one thing, while actually doing damage is being able to attack and also damaging it.
