Arrokuda is a brown and tan fish Pokémon resembling a barracuda. It has two big black eyes and two small jaws pointing upward, the latter of which it is very proud of. It also has five fins scattered on its body; two pelvic fins, two anal fins, and one dorsal fin. The Pokémon has two red spots, one behind each jaw, as well as three white scales on each side of its body for a total of six. Arrokuda lastly has three back fins on its tail resembling a ship propeller, starting off tan in color, but having a brown coloring on the end.
Should Arrokuda see any movement near it, it will charge in a straight line using its sharp pointed jaws, though its movements tend to become sluggish when it eats too much, which is typically when Cramorant appear to swallow it up.
