Berserker-G is Gandrayda mimicking a Berserker Knight. It is the first form Gandrayda will shapeshift into, and is fought like a normal Berserker Knight, by firing back the Phazon orbs it unleashes at Samus to destroy the Phazite armor it is wearing and reach its weak point. When Gandrayda is dying, the Berserker Knight is one of the forms she shapeshifts into before Dark Samus absorbs her.
