Engine of Darkness

The B-666 Bloonian Shadow Generator, or more commonly known as the Engine of Darkness, is an immensely-powerful shield generator that is capable of shielding the entirety of the Bloonian System from Monkey detection and Sun God attack. It appears in Bloons: Insurgency and BTD7: Planet of the Apes.

First construction

Mechanism
The Engine of Darkness harnesses dark energy and Bloptonite to construct a massive force field of shadow that can cover an entire solar system. All forms of radiation coming in and out of the force field are completely dissipated as they move through the edge of the shield, save for gamma radiation which is 99.9% dissipated, allowing only 0.01% to escape, which is virtually untraceable. Moreover, the space within the shield is filled with Bloptonite particles which can quickly incapacitate and kill any Bloptonians within the shield, preventing an attack from the Sun Gods and their Avatars.

Trivia

 * Inspired by the shield generator stationed on Endor that protected the Death Star II from attack in Star Wars Episode VI - Return of the Jedi.
