WATER Element colosus.
Conqueror of all oceans, the name Pearlena also was given when the colossus is in human form. Her necklace transform her into a destructive colossus. The Pearl on her chest creates a magical waterfall and form a whirlpool which absorb near by objects into the Abyss.
I got the idea from sea turtles, prawns, crab and rock fish.
