Prospector

The Prospector is the fifth boss encountered in Iridion 3D.

Battle
The Prospector shoot bullets at the player with two outstretching arms. After a few seconds, it'll open the center of it, revealing its weakness. However, even with the weakness exposed, it'll still shoot at the player. Continuing to dodge the bullets and destroying its weakness, the Prospector is defeated, and the player will move on to the Iridion Home Base.

Trivia

 * This is the largest boss encountered in the game.
 * Strangely, this boss fight shares the same background as the Outer Space Asteroid Field stage. This also applies to the Cytector in Dogfight Above the Pacific Ocean.
