The creator of Dragon Ball, one of the most influential and best-selling Japanese comics of all time, has died at 68.
Akira Toriyama succumbed to acute subdural hematoma, a type of bleeding near the brain, his studio said Friday.
Dragon Ball is hugely popular around the world and the comic series has also spawned cartoon and film versions.
Fans have paid tribute to Mr Toriyama for creating characters that have become a part of their childhood.
The Dragon Ball comic series debuted in 1984. It follows a boy named Son Goku in his quest to collect magical dragon balls to defend Earth against alien humanoids called Saiyans.
Mr Toriyama had uncompleted works at the time of his death.
He died on 1 March and only his family and very few friends attended his funeral, according to a statement from the Dragon Ball website.
Very sad to see him die. Loved the series.
