Masuda noted Lucario's name as one of the most difficult to create, due to an effort to make it appealing to both Japanese and American audiences. Lucario is a canid-like Pokémon partly based on Anubis, the jackalheaded god of death from Egyptian mythology that is a bipedal digitigrade with finger-like digits on its forepaws. Its chest and the exterior of its wrists each feature a single, white spike. It also has a large snout and ears, red irises with vertical slit pupils, an "hourglass"-shaped figure with leering thighs significantly thicker than the rest of its body, iron rings incorporated into its shoulders and waist, and a raccoon's "mask" that loosely resembles a khakkhara with four small dreadlock-like appendages on the back of its head that are used to sense Aura. The coloration of Lucario's fur is predominantly blue and black, although its torso features buff-colored fur slightly shaggier than the rest of its body. When it opens its mouth wide enough, sharp fangs can be seen. Appearances In the video games Lucario's debut and video game appearance is in Pokémon Mystery Dungeon: Blue Rescue Team and Red Rescue Team, though it only appears as a Statue Cameo when the player gets 15,000 points and the Lucario rank (the highest rank in the game). It then appeared in Pokémon Diamond and Pearl, where its pre-evolved form, Riolu, can be obtained as an egg from Riley. Riolu evolves into Lucario when it reaches a sufficiently high level of happiness. Lucario is used by notable trainers Maylene, the third Sinnoh Gym Leader; a tag team partner known as Riley; Cynthia, Sinnoh's Elite Four Champion; and by Bruno, an Elite Four member of Johto. In Pokémon Mystery Dungeon Lucario is perceived as the greatest rescue leader of all time, and his adventures have become legendary. After reaching a certain number of points, a Lucario statue will be displayed outside the rescue base. While the player never meets Lucario, Alakazam tells the player that his goal is to become closer to Lucario's greatness. Lucario can be found and befriended in Lost Wilderness dungeon in Pokémon Mystery Dungeon Explorers of Time and Darkness, but it has no particular main role. However, in Pokémon Mystery Dungeon Explorers of Sky and Pokémon Super Mystery Dungeon, its pre-evolution form Riolu may be played as the main character or be chosen as the partner Pokémon.
