Moai Orb is the third boss of Gradius ReBirth. The boss's weak spot is a red orb which is located in the forehead of the giant Moai's head.

Attack Patterns

The boss will unleash a flurry of lasers, with little gaps to slip through. Afterwards, the orb will start to bounce around the area, creating thunder bolts. Moai heads will attack along with the orb. The orb will then return to the forehead of the giant moai head, repeating this process until you destroy it. Once defeated, the boss will scream while exploding while falling into space.


Overall,the boss isn't difficult as long as you have a few multiples when you fight it. It's recommended to have missiles and 2 speed upgrades.
