Astra is the Host for the Angel Protocol, The Angel Protocol, referred to as "The Angel", is a program that naturally mutated in AI. Although similar to the Absolute Solver, the Angel mutated as a counter to it, without human intervention.

Unlike The Solver, The Angel disguises itself with its own body, instead of using others as hosts. It will occasionally integrate itself into a drone's code, but only when necessary. It rarely stays in the code. It's original state is more of a ghostly composure rather than flesh. Because of this, it might seem glitchy and distorted to some drones, more commonly with drones infected by The Solver.

The Angel's abilities are very similar to the Solver's, although using creation commands like "string" instead of [null].
