Turbo Norimaki is Senbei's and Midori's first and only biological child. He is also a genius, far surpassing his father in intellect.
In Dr. Slump, Turbo is nearly killed by aliens and then revived by them, in the process of imbuing him with many super powers including teleportation, flight, technopathy, and telekinesis.
When Goku asks Senbei to repair the Dragon Radar, Turbo quickly fixes it with his psychic powers knowing his dad would not be able to fix it, and after Arale defeats General Blue and accidentally forgets to get the radar back, he makes a new one with the parts to Senbei's plane for Goku, using his powers. He also lifts the effects of General Blue's Look into my eyes! technique from Goku.
