Multiple towers can be OP in certain rounds and situations.

For instance, the Ninja Monkey performs as a good tower for the first several rounds, due to the fact that it can pop multiple bloons at once and detect bloons with the camo status, even without upgrades, making it a good starter tower. In the next few rounds, upgrading it to 3/1 or even 3/2 will make it even better. It can distract bloons, throw two shurikens at once and do other nice things.

Next, I could say that the Super Monkey itself at later rounds is actually pretty OP when upgraded to the max temple with all sacrifices. It can easily demolish any bloon in no time (I'm not sure if it can kill DDTs, though), making one tower already enough to destroy a heck a lot of bloons.

Another tower that is OP (and very useful) in later rounds is the Spike Factory. Where to start? Anyway, these towers are very useful and OP in multiple ways:
 * The Spike Factory can automatically produce its road spikes without any problem. This can (heavily) reduce the use of Road Spikes.
 * Its special ability covers the entire path of the track. This ability can be useful if there are tons and tons of bloons all over the path.
 * This is the best tower that can encounter the most infamous bloon: the DDT, well, only if it has White Hot Spikes or if it is under an x/2 Monkey Village.

To me, the most 2 OP towers IMO are the Monkey Village and the Banana Farm. Despite both towers usually not being able to attack bloons (except for 4/x Monkey Village), the Monkey Village can actually buff the towers in its radius in certain ways, and even lower their costs, making this a very valuable and useful tower. While the Banana Farm can never attack no matter what upgrade, it can give the player extra money from the tower's bananas. This is especially useful for the CT mode from Bloons Monkey City, as it is actually much harder to get money from that mode in later rounds without them.
