Grand Kai Character Facts

Grand Kai oversees the four Kais, North Kai, West Kai, South Kai and East Kai, who rule over the four quadrants of the universe. 
Grand Kai is considerably stronger than the other Kais and is known to be the greatest fighter in the four galaxies. Even though he is the teacher of the greatest warriors in the universe, Grand Kai (much like North Kai and Master Roshi) is more of a sweet and a kind grandfatherly figure than a traditional disciplinarian. 
Paying no heed to respectful-but-cold formality, he lovingly treats his social-inferiors as equals and dotes on them as if they were his own grandchildren.
