Kibito serves as the Supreme Kai's most trusted aide and personal bodyguard. His name comes from the Japanese word for "attendant," which pretty much sums up his role—he's been helping out the Supreme Kais since way back.
He's notably tall; Gohan even calls him "big guy" when they meet. Beyond just being physically imposing, Kibito's got some serious magical abilities in his toolkit, including Instantaneous Movement and healing powers, which made him invaluable to the Supreme Kais before most of them were wiped out by Majin Buu.
After that catastrophe, he stuck with the Eastern Supreme Kai as a dedicated bodyguard and has remained loyal ever since. That said, he's not without his insecurities—fans often note that he gets a bit jealous of Gohan's strength, which adds an interesting layer to his character. He's devoted, but definitely not immune to pride.
