Skorupi is an over-sized, blue scorpion-like Pokémon. Its claws and tail have been swapped, giving it two stingers and a claw tail. The miniature jaws, claws, and tail claws are white. Its arms are attached directly to its head, close to its turquoise eyes. A pointed marking joins its eyes. The head, arms, two tail segments, and all four legs are light blue, while the body, tail end, and other two tail segments are dark blue. It buries itself in sand and lies in wait for unsuspecting prey, and grips prey with its tail claws, injecting poison; it will then hold on until the poison takes effect. Skorupi is found in deserts and dry areas like Reversal Mountain, though it can be found in marshy areas such as the Great Marsh.
