Straight from Konami, and confirming what the Counter from the pack is supposed to be. (Hint, it’s B.E.S. related)

Uria, Lord of Searing Flames
D.D. Crow
Downerd Magician
Lyna the Light Charmer
House Duston
Boss Rush
Skyscraper
Magic Planter
Tornado Wall
Counter (B.E.S. Shield)

The Counter lists the shield as a Weak Point, in true Gradius fashion
