Contrary to popular belief, Toriyama DID have a role in anime-only material on Dragon Ball Z (1989). He created Bardock and Pikkon, and it was his idea to have Yamcha as a baseball player.
He often carried out crossovers between his works "Dragon Ball" and "Dr Slump". In Dragon Ball (1986), Dr's Slump's home Penguin Village appears for a few episodes in the General Blue saga. Likewise, Arale Norimaki, Dr Slump's daughter, makes a few cameo appearances throughout the Dragon Ball saga; in a similar manner, when Toriyama started a new "Dr Slump" series following the end of "Dragon Ball", Goku made a cameo appearance.
Is friends with Eiichiro Oda, who credits Toriyama as an influence on his manga "One Piece". The two worked together on a crossover called "Cross Epoch", where both "Dragon Ball" and "One Piece" characters had to get to a tea party (but a series of misadventures kept getting in their way).
Has a son, Sasuke (born April 1987) & a girl (October 1990).
His "Dragon Ball" manga extended only up to the end of the DBZ series and the third anime series Dragon Ball GT (1996), was an original work (and thus considered by some fans to be non-canon); however, Toriyama was involved in that series by supervising its production, although this was limited.
His "Dragon Ball" protagonist Son Goku was voted in a 2009 poll by Mania.com as the most iconic anime hero of all time.
He planned to end "Dragon Ball" with the Frieza saga (where Goku faces Frieza, the destroyer of his planet), but his publishers persuaded him to carry on the saga to include the Android, Cell and Buu sagas.
He claims not to plan his stories in the long-term.
In Japan, May 9 is officially known as Goku Day, after his hero Goku (May 9, or 5-9, can be written in Japanese as as "go"-"ku").
Personal Quotes (3)
About Drunken Master (1978): If I hadn't seen this movie, I would never have come up with Dragonball.
His favourite "Dragonball" character: I believe mine would be Piccolo. He was the first character in my manga where I was like, "He has a scary face, but he's so cool!" It really is cliché when bad guys turn into good guys, but it just feels great drawing it!
About Blue Dragon (2007): "This may be my final anime, I'm a little worried (about it). There's incredible pressure, but at the same time, there's a sense of accomplishment - that it's worth doing. Blue Dragon will be a masterpiece, not simply because I'm working hard on it, but because the staff is expecting nothing less."
