Toriyama was commissioned to illustrate the characters and monsters for the first "Dragon Quest" video game (1986) in order to separate it from other role-playing games of the time. He has since worked on every title in the series. For each game Yuji Horii first sends rough sketches of the characters with their background information to Toriyama, who then re-draws them. Lastly, Horii approves the finished work. Toriyama explained in 1995 that for video games, because the sprites are so small, as long as they have a distinguishing feature so people can tell which character it is, he can make complex designs without concern of having to reproduce it like he usually would in manga. Besides the character and monster designs, Toriyama also does the games' packaging art and, for "Dragon Quest VIII", the boats and ships. In 2016, Toriyama revealed that because of the series' established time period and setting, his artistic options are limited, which makes every iteration harder to design for than the last. The series' Slime character, which has become a sort of mascot for the franchise, is considered to be one of the most recognizable figures in gaming.
