Background
Disrupt first appeared in Gradius 3 AC, as the first sub-boss of stage 10. He went on to reprise this role in Gradius 3 SNES, where he was the first sub-boss of stage 9. In both appearances he had three cores with four barriers each, and several laser cannons. He also had four hatches, two of which spawned Duckers, while the other two spawned flying enemies.
Attack Pattern
Disrupts' attack patter is simple, he fires his cannons while periodically releasing enemies from it's hatches. In Gradius 3 AC, though, there was a moving floor and cieling, limiting your movements. The hatches could not be destroyed as well. His SNES incarnation had no moving walls, and the hatches could be destroyed as well, making him defenseless, and you could destroy him at your leasure.
