Disruptors are the deadliest and one of the dangerous enemies of the Battura fleet that appears in both Star Luster and Star Ixiom. Fortunately, you'll never deal with more than one of them (with one exception in Adventure mode), and only after the majority of the squadron is defeated. They're the strongest offensively and defensively. The fact that they are slow is no help. That just means they will have greater opportunity to fire at you as you get closer to them, and their shots are entirely destructive. One shot from a purple Disruptor will completely destroy Gaia! Constant motion is highly advised when you attempt to take these on. Standing still is an invitation for annihilation. The Big Disruptor is the predecessor to the original Disruptors.
