The Bazillions are a set of four laser guns that was created by an ancient super-civilization with the power to destroy the molecular bonds of their targets. They were also powered with the power of Inferno by Rodin before he gave them to Bayonetta and Jeanne.

In game description
"Four guns created by an unknown super-civilization. Powered by an energy source known as Bazillionium, the deep crimson flash from the guns instantly break down the molecular bonds within its target. Able to discern the intent of its user, it is said that these strange, miraculous guns have the power to open a portal to another dimension. Thanks to Rodin, the guns have also gained demonic powers, making them an incredible threat to the denizens of Paradiso."
