Ripjaws is the Omnitrix MK10's DNA sample of a Piscciss Volann from the planet Piscciss.
In The New Omniverse, Ripjaws has his original appearance, except that his eyes are green, he now has arm and neck braces, his antenna light is green, he has a big fin on his back and his tail is now bigger. He speaks in a higher, garbled voice, slightly similar to how a person sounds underwater.
16 year old Ripjaws now has a belt in place of the strap. The Omnitrix MK10 symbol is on his belt.
Ripjaws is strong and is able to lift more than his own weight. He can also easily punch a hole in a dock.
Ripjaws is highly agile and dexterous.
Ripjaws' large jaws and sharp teeth have proven to be his most deadly weapon, being able to shred even metal from submarines. He also possesses sharp claws that can damage metal.
Ripjaws is able to breathe underwater, as well as swim at high speeds with amazing agility. He has great endurance and can withstand strong water pressure, meaning he possesses the nature of abyssal aquatic life, hence his blank eyes and the anglerfish light in his forehead, which can serve as a light in dark areas.
Ripjaws displays the distinctive feature of turning his legs into a fish's tail and vice-versa, giving him a merman-like appearance, while outside the water environment, he displays a loincloth with a similar pattern to his tail (implying the loincloth wraps around his legs, fusing with it and becoming the tail). While his legs are formed into a tail, Ripjaws can swim very well at great speeds.
Ripjaws is able to fit a mass supply of objects in his mouth, as shown in Gone Fishin'.
Ripjaws' greatest weakness is his inability to stay out of water for too long, requiring it to keep him from dehydrating. However, he needs it less in Omniverse, since Piscciss Volanns do not rely on water as much as they get older.
