Kappa

Kappas are a race of beings that hail from Japan, but are now spread worldwide.

Appearance
Kappas basically look like humanoid turtle/frog hybrids, with muddy, brownish-green, scaly skin, a beak-like nose/mouth, fangs, claws, a shell on their backs, webbed hands and feet, greenish eyes, and a ring of hair on top of their heads. However, they have two characteristics that separate them from other species. First, they have a very fishy odor. Second, they have an indentation on top of their heads, called a sara, which is usually filled with water. When the kappa is on land, they usually have a metal cap covering their sara.

Behavior
Kappas tend to live in rivers, streams, lakes, and ponds. They also tend to be loners until they find a mate. Then, and only then, does a kappa live with another. Kappa tend to be mischievous, and love pulling good pranks, however, like the tanuki, they will never do a prank that they think will be emotionally or physically harmful to the victim.

Powers

 * Enhanced agility: Kappas are able to go from one movement to another effortlessly, allowing them to effectively dodge attacks, swing from things, do backflips, and numerous other gymnastic, athletic, and martial implements with little effort.
 * Enhanced bite: Kappas, due to their turtle-like beak and fangs, possess a powerful bite.
 * Enhanced durability: Kappa are able to withstand numerous blows of internal or external assaults.
 * Enhanced endurance: Kappas are able to survive with little to no energy for an extended amount of time.
 * Enhanced jump: Kappas are able to achieve rocket-like jumps, while having hassle-free landings.
 * Enhanced lung capacity: Kappas have tremendous lung capacity, and are able to use oxygen very efficiently.
 * Enhanced strength: Kappas are able to exert a great amount of strength from their muscles.
 * Speed swimming: Kappas are able to swim at incredible speeds, regardless of water resistance.
 * Night vision: Kappas are able to see clearly and easily in low-light conditions and/or complete darkness.
 * Shell: Kappas are able to use the shells on their backs and fronts as effective shields, and are able to pull their arms, legs, and heads into their shells as well.
 * Claws: Kappas are able to use their claws as effective weapons.
 * Aquatic respiration: Kappas are able to breathe both water and air, similarly to merfolk.

Weaknesses

 * Sara: When kappas are on land, their greatest weakness is the sara on top of his/her head. This is because the sara is filled with liquid, and if the liquid is spilled, the kappa will become weak and, if enough is spilled, paralyzed.
