- In-game Description

Bionic Boomerang is the 3rd upgrade on Path 2 of the Boomerang Monkey in Bloons TD Battles 2. It is almost identical to its BTD6 counterpart. it attacks much faster than an x2x boomerang monkey (every 0.238s), and does +2 damage against MOAB-class bloons.

It costs $1,450.

Summary
An all-round strong early-game tower that reliably hits spaced bloons, as well as grouped bloons when given Glaives. The extra MOAB damage is fairly small, and only really comes into play with Turbo Charge.

Tips

 * 2-3-0 is usually better for the much greater pierce, though 0-3-2 can be useful when going for 0-4-2 for better single-target DPS or just needing to pop Leads.
