Akira Toriyama was born in 1955 and became a manga artist at 23. Primarily known for his works in Weekly Shōnen Jump for works such as Dr. Slump, his biggest claim to fame would be Dragon Ball. First published in 1983, Dragon Ball would explode into a cultural phenomenon, spawning a massively popular multimedia franchise with multiple manga volumes, a successful long-running anime, several films, and a litany of merchandise. Dragon Ball has become one of the most influential mangas of all time and would also become a massive fixture in video games, with dozens of titles across a variety of platforms. 

Upcoming games based on Toryiama’s work include Dragon Ball: Sparking Zero, the next entry in the Budakai Tenkaichi series, and Sand Land, an action RPG launching on April 26 based on his 2000 manga. 

Toryiama would also lend his distinct art style to video games such as the Dragon Quest series, Chrono Trigger, and Blue Dragon. Six years ago, Game Informer editors current and former got together to talk about Toriyama’s influence on the game industry. You can watch that video here.

Game Informer extends its condolences to Toriyama’s family and loved ones.
