Maru Maru is made up of four small, circular craft, which can combine into one much larger ship.
The large ship is invincible but the smaller craft can be destroyed.
These four craft rotate around the screen and quickly come together to form the large ship.
This ship will rebound around the boss area with great speed and care must be taken to avoid it.
Whilst this is happening, minor enemies will occasionally spawn and fly vertically between the floor and ceiling, giving you an extra obstacle to deal with.
Eventually the large ship will break apart and you can press on the attack again.
When all four craft are destroyed, you will have to take on Striker
- With the popular theory that Gradius ReBirth is based off Nemesis GB, it is generally believed that this Sub Boss was used as a the basis for the Moai Orb boss.
