Bionic Boomer

"This tower replaces its arm with a super strong bionic arm. The Bionic Boomer throws boomerangs twice as fast."

- Official description in BTD5

 is the third upgrade on the second path for the Boomerang Thrower that made its debut in Bloons TD 5. Although the description states it fires twice as fast, it actually shoots much faster. In BTD5, it actually fires around 3.2x as fast as a non-upgraded Boomerang Thrower and 4x faster with the Glaive Thrower upgrade. The upgrade makes the tower shoot a nearly constant stream of projectiles, shredding the Bloons away. Although this upgrade "diminishes" the need for the Boomerang Thrower's need to be placed near an elliptical curve, the tower will still do much better if it's placed near one. It costs $1360 (Easy), $1600 (Medium), $1730 (Hard), $1920 (Impoppable).

Tips
Compared to its counterpart the Bionic Boomer is more reliable in terms of defense and is far stronger against regrow bloons while Glaive Richochet is useful at weakening large group of bloons outside of its range, however its very weak against regrow bloons causing a regen farm if unnasisted.

Its advised to place Bionic Boomer on place where it can cover multiple if not most of the track to maximize its fast throwing speed and moderate pierce.

BTD6
In BTD6, it returns as Bionic Boomerang.
