Gunner Wall is the 2nd boss of final stage from Gradius Gaiden before the Heavy Ducker. It is a upgraded version of Demos from Gradius II. Just like the predecessor with a giant core and the the wall side to create guarding the Player to processing.
The Gunner Wall will attack with the multiple lasers and release more drones to attack you. After a while, it will charge at you then fire a small wave of lasers in Straight to trap you until it moves back and repeats the cycle all over again. It's easy when you use the Vic Viper or Falchion Beta.
- This type of Gunwall lacks hatches, unlike Demos in Gradius II. It contain fighters inside his hatch.
- Its attack patterns were inspired on the boss Black Heart from Battle Garegga.
