Perla Meralda appears to have a combination of other Core's attacks. At first, Perla Meralda will use four lasers, similar to Big Core MK I. It will fire this pattern 4 times before moving to the center of the screen. Next, it will engage its two large lasers it has to trap the player in an area (like Big Core MK III), which it will move around the screen. As it does this, it will also be firing missiles which will head up or down through the barricaded area, similar to Covered Core's missiles.
After this, it will deactivate its lasers, and go back to firing 4 lasers again. After four more volleys, it will head to the center of the screen once again, charge up its lasers, and rapid fire with them while moving left across the screen. After that, it will restart its attack pattern. Perla Meralda can apparently have its large lasers destroyed, and will stop moving if this happens.
- The term Perla Meralda comes from the spanish word "Perla Esmeralda" which means "Pearl Emerald", seems that Konami's people mistranslated the name.
