Crystal Lize is the fourth stage of Metal Black.
The journey continues further into the Earth-Jupiter wormhole, The Black Fly encounters another alternate dimension filled with rock formations and bizarre mineral-based life-forms.
The boss of this level is a living missile called Amazo.
- The Ocean Sunfish Captain seen on Stage 2 returns. Is very similar to Heat Arrow from Super Darius II and its the precursor of Odious Trident from Darius Gaiden.
- The "Newalone Picking Worm" resembles a small version of Driosawm from Darius II.
- Altough Amazo is somehow based on an Ammodytes dubius, it is the precursor of Titanic Lance (an Orthocerida) from Darius Gaiden.
