Sinker (Lilo & Stitch)

Experiment 602 A.K.A. Sinker is a shark-like alien that is part of the 600 series. Much like its successors he causes havoc and other forms of chaos and destruction; this little devil is capable of not only swimming at high speeds but also surviving underwater despite not having visible gills. The primary function of this aquatic menace is to sink ships with his massive dorsal fin making him basically the king of the seas. He will attack any ship that enters the water and it does not matter on how big the ship is his dorsal fin is capable of causing sufficient damage to split it in two. After capture and rehabilitation he now works as a stir fry cook.
