Ever since Dragon Ball‘s serialization in Weekly Shōnen Jump ended in 1995, the series has been included or parodied to some extent in numerous other manga series. This is largely due to the series’ significant impact and influence on the then up-and-coming manga artists, such as Ei’ichirō Oda. Some artists have even created entire crossover chapters between their own series and Dragon Ball, often including significant collaborative input from Akira Toriyama himself.
