Liepard is a quadrupedal mammalian Pokémon that resembles various felines, namely a leopard, a leopard cat, and a black panther. Its body is long, slender, and lithe, with powerfully-built muscles. Its coat is mainly purple with small yellow rosettes speckling its back. Its undercoat, including its legs, chest, underbelly, and much of its face, are yellow. It has vivid pink "eyeshadow" around its slanted green eyes. Two long yellow whiskers protrude from either side of its face. Like Purrloin, its tail is somewhat hook shaped.
Liepard are nocturnal Pokémon. They are excellent hunters, stalking their prey silently at night, and swiftly striking from behind before their victims have a chance to react. They are very mysterious, seeming to vanish and appear unexpectedly. For example, they use their charm to cheat the opponents in order to heist their belongings. As a trainer's rare Pokémon, Liepard love boasting their talents by stunting their trainers. Sometimes they also make themselves as well-behaved "pets".
Liepard are skilled, swift hunters. They have powerful, limber muscles, and are very stealthy, sneaking about in utter silence at night.
