A Kelpie is a sea creature that lives in oceans. It is a shape-shifting monster that takes the power of any magical creature on which it feeds.
It looks like a huge fish-man with green scales, fins on its back, its head, and its arms and legs, and it also has yellow eyes.
This creature is very aggressive against people and magical creatures. It will attack and bite anyone and it seems to know who Jake is and wants to take his powers. When it was captured, it was in chains and it was muzzled.
Shape-shifting/Transformation: The Kelpie feeds so it can assume the form or shape or powers of whatever magical creatures or non magical creature on which it feeds. When it feeds it drains the creatures essence and sends the creatures soul into total darkness.
Fangs/Canine-teeth: The Kelpie has sharp teeth that can bite creatures. It prefers to bite the neck so it would be easier and quicker to drain a magical creatures abilities and form although it keeps its voice while assuming another form.
Super-Strength: The Kelpie while in its regular form possess inhuman strength, speed and reflexes it is a formidable foe and strong enough to take down a dragon. This is why it is one of the most dangerous sea creatures in the magical world.
Strategic ability: Kelpie prefers a stealthy approach when coming into contact with a powerful magical creature such as a dragon. It also finds a way to strike from the inside and make sure the target does not have a clue that it is being hunted.
