Turbo Norimaki is Senbei and Midori's first biological child. He is a genius, even surpassing his father.
He was killed by aliens and then revived by them, in the process imbuing him with many super powers including teleportation, flight, and telekinesis.
When Goku asked Senbei to fix the Dragon Radar, Turbo quickly fixed it with his psychic powers knowing his dad wouldn't be able to fix it. Arale defeated General Blue and accidentally forgot to get the radar back. He makes a new one with the parts to Senbei's plane for Goku using his powers. He also undid General Blue's telekinesis on Goku.
- Many generic babies shown in Dragon Ball are of the exact same character design as Turbo.
- "Turbo" was also the name of Akira Toriyama's dog, at the time.
