Berial is the boss of stage 6 in Gradius IV.
Berial attacks by firing beams from its weak point, the eye and creates option-like eyes that also fires beams. When you defeat Berial, the eye remains. It grows into Zelos Force. Zelos will fire two volleys of beams before self-destructing. Lots of Gradius players hate that especially when they've got hit a bunch of times, but a good strategy to avoid that is as soon as Zelos fires his beams push pause to see where they're going then unpause when you see them.
Berial is one of the very few Organic Fortress guardians that actively move to attack the player. The only other guardian that's capable of doing this is Abadon's second form.
