Neo Big Core is a drastic modification of Big Core MK I. It is the fake last boss of the boss rush in Gradius Gaiden. It is barely similar to Big Core MK I, with the only similar features being moving up and down, its core number, and shooting four shots. The death animation consists of many mini-nukes exploding. The boss equipped with Funnel/Drone weaponry on higher loops, making it a drastic fight.
Neo Big Core's initial attack is shooting four cube-like lasers in front. However, the top and bottom shot bend at a slight angle. While doing this, it also moves up and down at various speeds. It will sometimes rapid fire the four shot and move up and down very fast as though in a frenzy. After some time, it will come close and release a wide beam that covers 1/3 of the screen about 2 seconds after it's released.
At higher difficulties/loops, it also releases drones up and down that shoot lasers. Occasionally, it will release a mini-nuke bomb in front that explodes with a big radius. Also, every once in a while it will attempt to ram you and while it returns to the other side of the screen, releases several mini-nuke bombs that aim at you and explode.
