In the Sonic the Hedgehog series, there are arguably a few references to Dragon Ball. Both the Chaos Emeralds and Super Sonic are nods to Toriyama's work. (Super Sonic is debatable, however, as the 'golden warrior' is a common Japanese legend and where Toriayama got his original inspiration for the Super Saiya-jin design.) According to the Japanese strategy guide for Sonic Jam, the special stages in Sonic the Hedgehog 3 and Sonic & Knuckles were inspired by King Kai's planet. The Jewel Radar, which bears a strong visual and functional resemblance to the Dragon Radar, is mentioned in the Sonic the Hedgehog 3 Japanese manual and appears in Sonic Riders.
