Ripjaws

Ripjaws is a Pisciss Volann from the planet Piscciss.

Appearance
Ripjaws appears shares a number of traits of Earth aquatic life, alligators, eels, anglerfish and sharks. He has shark teeth, has a tail like a mermaid when underwater, and has a phosphorescent light on his head. He is able to breathe underwater, and is usually the best alien for to use in defeating water-based villains. Ripjaws can swim at high speeds with amazing agility, and can also withstand amazing pressure. His luminescent angler allows him to see in dark areas. Ripjaws can breathe on land depending on its age.

Abilities
Ripjaws uses his claw-tipped fins and razor-sharp teeth to attack enemies with strength superior to a person. Similar to a snake's eating habits, Ripjaws can unhinge his lower jaw to swallow large objects in a single bite. He can transform his legs into a tail when he's underwater, by bringing both of his legs underneath the black loincloth coming down.

Weaknesses
Ripjaws's greatest weakness is his inability to stay out of water from too long, requiring water to keep him from dehydrating. As a result, Ben often takes action by claiming nearby water sources (e.g. hosepipes). Ripjaws has a pair of webbed feet inside his tail, which can temporarily keep him on land for a few minutes. There is a suit that allows Ripjaws to walk on land. The device covers the gills on his neck giving it water. With this Ripjaws can walk on land not worrying about the need of water and dehydrating.
