Game info: Hit these sopping scoundrels while they're coated in water and they'll only teleport away. That's your cue to bring the magical heat; a Fire spell will evaporate that shield in no time. Don't get caught in their rain, or you'll come down with the extremely annoying cloud status.
Wiki info: The Water Core is a Pureblood Heartless that appears in Kingdom Hearts 0.2 Birth by Sleep -A fragmentary passage- and Kingdom Hearts III. They are first seen in groups, flooding rivers in Olympus. When defeating them the flooded rivers will decrease in size. They resemble the Flame Cores with a few differences. They have black bodies with blue water spikes dangling around them, small skinny wings with hands at the ends, and small blue veins on their heads. One of their attacks is consisting of covering themselves in water, which will help them teleport if attacking head on, only by using a fire spell will the shields go away and you can defeat them then.
