Darius, Darius Plus, Darius Alpha, Super Darius and Super Darius II

This fight is very similar to Iron Hammer with the biggest difference being that its weakspot (its mouth) is only vulnerable when it attacks. Its attacks consist of small laser shots from it pectoral (lower) fin, four separate thick laser shot from its dorsal (upper) fin and single fireballs from its mouth (this is the only time you can damage it by shooting at its mouth before it closes it)

All his attacks besides the fireball attack are triggered when you are positioned in front of the bodypart that launches that certain attack. Hopefully, both fins can be destroyed to neutralize the attacks, leaving only the fireball attack to deal with.

Weak point(s)

The main weak point of Keen Bayonet, like most Darius Battleships is his mouth, that can be exposed only when K.B. attacks. You can disarm K.B by destroying his upper and lower fins.
