"OP" and "UP" are not terms defined by this wiki, but rather, by this wiki's users.

Anyway, many towers have a powerful fourth tier upgrade. The Temple and Technological Terror are both among the most powerful of upgrades. This is not to say other towers are not powerful. Many towers can achieve what others cannot. Super Wide Funnel Bloonchippers can dish large amounts of damage towards blimps, 4/x Snipers can stun BFBs and MOABs, yet both are useless against Pink rushes.

Ground Zero Ability has full map coverage and can single-handedly take on MOAB rushes (perhaps BFB rushes) but are pretty much useless against ZOMGs. Technological Terror's Bloon Annihliation Ability can dish out huge damage to blimps, yet has a smaller range than Ground Zero.

There are many other powerful towers (if I listed them here, the post would be very long), but all towers are powerful in their own respect.
