The announcement came on the day publishing house Hachette celebrated the sale of 350 million Asterix books around the world, making the diminutive hero one of France's biggest-selling exports.
"I've decided that there should be some continuity, and I want it to carry on for generations and generations," Uderzo told RTL radio.
Following the death of Goscinny in 1977, Uderzo took over both the writing and artwork for the comic book, drawing criticism from die-hard fans who felt his scripts lacked Goscinny's humour and irony.
The recent appearance of Asterix and his friends in a billboard advertising campaign for McDonald's also sparked outcry, with some accusing Uderzo of selling out the diminutive Gaul to capitalist invaders.
