Hunter-X

The Hunter X is the most powerful of all the enemy ships found on various Gummi Missions in Kingdom Hearts II. The Hunter X is a relative of the Hunter, and only appears at the end of Mission 3 on Assault of the Dreadnought. It has multiple limbs which fire various shots at regular intervals, along with four Hunter X Bombs which fire waves of Power Shots.

Strategy
The Hunter X's series of attacks start with firing a multitude of Power Shots and Lasers at the Gummi Ship, followed by waves of normal shots which rotate around the screen counter-clockwise. After that, it fires a series of Blast Shots that hit everywhere but the middle of the screen, followed by left-to-right Blast Shots that start at the lower-left hand corner of the screen. Then it fires all shots at the same time, still avoiding the center of the screen. It then unleashes its most devastating attack, firing a + shaped Laser, then an X shaped one. This attack can destroy a Gummi Ship in one blow. This entire process repeats until the Hunter X gets low on HP. Then it fires everything in its arsenal randomly in a desperate attempt to destroy the Gummi Ship. If some of its limbs and the Hunter X Bombs are destroyed, some of its attacks (such as the Blast Shots) can be removed, and it makes defeating the Hunter X much easier.

When the Hunter X is defeated, it coughs up the last Original Blueprint, the Secret Model.

Trivia
Sharp-eyed players will note after the Hunter X is defeated, it releases a Heart, making it a Heartless.
