Krookodile is a large, bulky reptilian crocodile-like Pokémon. Its body is mainly brick-red in color, and covered in black stripes with pointed ends; it has a round gray belly. It has considerably large and razor-sharp teeth and claws. Around its eyes, there is a black patch resembling a bandit's mask, or a stylized pair of sunglasses. It somewhat resembles the dinosaur Baryonyx or Tyrannosaurus rex.
Krookodile has the highest base stat total of any non-legendary Ground-type Pokémon released in the Fifth Generation (509), edging out Excadrill's 508 base stat total by one point. Not counting Hydreigon among Dark-types, Krookodile is in-turn only edged out by Zoroark in terms of base stat totals by one point (510).
Despite being named Krookodile, it is actually modeled after the Gavial, a species related to the crocodile. This is also reflected in its Japanese name, which is a combination of Waru, form the word warui, meaning bad, and Vial, from Gavial. It also somewhat resembles the dinosaur Baryonyx or Tyrannosaurus rex.
Krookodile's English name is derived from a corruption of the word "crook" (a villainous person), and "crocodile".
