Lucky Luke is a Belgian comics series created by Belgian cartoonist Maurice De Bevere, better known as Morris, and for one period written by René Goscinny. Set in the American Old West, it stars the titular character, Lucky Luke, the cowboy known to "shoot faster than his shadow". His name is inspired by that of Luciano Locarno, an Italian American sheriff who lived between 1860 and 1940. Along with The Adventures of Tintin and Asterix, Lucky Luke is one of the most popular and best-selling comic-book series in continental Europe. About half of the series' adventures have been translated into English. Lucky Luke comics have been translated into 23 languages, including many European languages, some African and Asian languages.

Metal Walker, known as Bakusou Senki Metal Walker GB: Kotetsu no Yuujou (爆走戦記 メタルウォーカーGB 鋼鉄の友情, lit. "Roaring Chronicle Metal Walker GB: Steel Friendship") in Japan, is a role-playing video game for the Game Boy Color, developed and published by Capcom. Many critics likened the game to the Pokémon series, but praised the game's unique qualities. In Japan, the game inspired merchandise based on the Metal Walker robots. Metal Walker's battles are unique from other games in the genre due to their billiard-style nature. Players move their Metal Walkers across the battlefield by hitting them into items, walls, or enemy Metal Walkers.
