Krookodile has a thick maroon-colored body, black back, and white stomach. It has five triangular spikes on its back: four around the middle of its back, and one large one at the beginning of its tail. Each of the smaller spikes on its back are linked to black, triangular spikes that reach around to its front, slightly overlapping its white stomach. The largest spike sits at the beginning of its long thick tail, which has three, thick, black stripes. The last stripe covers the tip of the tail. Its legs are very short and directly attached to its feet. The feet are wrapped in black and have three white claws facing forward. Krookodile's arms are short and thin with a black stripe around the elbow. Its long, thin fingers are each tipped with a white claw.
Its head is slightly pointed and contains a distinctive black membrane that surrounds both eyes. The outline of the membrane angles upward sharply, coming to points above the top of Krookodile's head. It uses this distinctive look to harshly intimidate opponents. Its eyes are very powerful, with variable focus, allowing it to see things at a great distance. Its other notable feature is its long snout, containing a black stripe around the bridge, and large pointed nostrils on the end. Four of its rear and two of its front teeth slightly overlap its lower jaw. Krookodile's jaws are extremely powerful, giving it the ability to crush object as large and durable as an automobile. These features are topped by Krookodile's extremely violent temper. It has been known to clamp down on any moving object, and will do everything it can to make sure its prey cannot escape.
