Toriyama admires Osamu Tezuka's "Astro Boy" and was impressed by Walt Disney's "One Hundred and One Dalmatians", which he remembers for its high-quality animation. Jackie Chan's early movies also had a noticeable influence on his stories, particularly Chan's martial arts comedy film "Drunken Master". Toriyama stated he was influenced by animator Toyoo Ashida and the anime television series adaptation of his own "Dragon Ball"; from which he learned that separating colors instead of blending them makes the art cleaner and coloring illustrations easier. It was Toriyama's sound effects in "Mysterious Rain Jack" that caught the eye of Kazuhiko Torishima, who explained that usually they are written in "katakana", but Toriyama used the Roman alphabet which he found refreshing. In his opinion, Torishima stated that Toriyama excels in black and white, utilizing black areas, as a result of not having had the money to buy screentone when he started drawing manga. He also described Toriyama as a master of convenience and "sloppy, but in a good way." For instance, in "Dragon Ball", destroying scenery in the environment and giving Super Saiyans blond hair were done in order to have less work in drawing and inking. Torishima claimed that Toriyama draws what he finds interesting and is not mindful of what his readers think.
