Millions of years before the beginning of the Dragonball world, there were four Kaioshins, North, South, East, and West. Each had a responsibility to uphold the peace in their respective section of the universe. They were peaceful gods with a kind (and fat) oversee-er, the Dai Kaioshin.
The universe was peacful until an evil magician, named Bibidi created his ultimate monster, Majin Buu. Along with his monster, he destroyed planet after planet, proving his Buu to be completely unbeatable. One peaceful day, Bibidi appeared and wrecked havoc on the five Kaioshins. West Kaioshin was the first to die, followed by North. South Kaioshin, the strongest besides Dai Kaioshin, put up a good fight, but was no match for Buu. He was abosorbed into the mosnter and made his power level increase significantly.
East Kaioshin was Buu's next target. He was inches from death until Dai Kaioshin intervened and attempted to kill Buu. The powerful monster was too strong for the god though, and soon he too was absorbed into the belly of the beast. An unlikely change took place however. Instead of becoming more powerful, Buu became fat and more jovial; traits given to him courtesy of the absorbed Dai Kaioshin. Bibidi was overjoyed because Buu was now able to be controlled, unlike his rebellious self before. The two wisked away, leaving East Kaioshin bruised, hurt, and desperate for revenge.
Kaioshin tracked down Bibidi and killed him. He thought that the ball containing a sealed up Buu would be safely hidden on Earth, for no one but Bibidi knew the charm to free him. Needless to say, he was wrong and so starts the Buu saga....
In short, a good god for the most part but needs to keep an equal check on everything in the universe. He seems to concetrate on only those matters which *he* thinks are of great concern and ignore the small details; it's these little matters though that end up biting him in the butt in the end.
Kaioshin, AKA "Supreme Kai" appears to Goku and the Others during the World Martial Arts Tournament. Despite his un-intimidating appearance, he rises the suspicion of Piccolo and even freezes the poor guy in his tracks during their match. He's considered a sketchy character until it's revealed that he is the Supreme Kai and has only good intentions for the people of Earth.
Along with his assistant Kibito, he informs the others that a terrbile force, Majin Buu, is about to be released from his captive ball by his creator's son, Babidi ("It can do magic believe it or not! Bibidi, Babidi, Buu." ~Cinderalla lyrics) Kaioshin has this master plan of his that once in place, will prevent Buu from being released and ever wrecking chaos on the Earth. Unfortunately, many events went against fate, and Kaioshin was un-able to convince any of the Saiyans that Buu would be the most terrible force they would ever encouter. Buu was then released thanks to the efforts of Vegeta, Dabura, and Babidi. (I'm skipping alot of parts here).
Buu is free and does his worst to the Z fighters (Goku and Gohan are unconscious and Vegeta is dead) and Kaioshin (who is a breath away from death). However, Bulma and the others use the Dragonballs to bring everyone (who is good hearted) back from the dead; these would be the people that Vegeta and Dabura killed. Kibito is ressurected and heals the ailing Kaioshin. After this reunion, Gohan is taken to Kaioshin's homeworld where he frees the Zet Sword (dubbed Z Sword). Out of the broken shards of the sword from an unfortunate accident, Rou Kaioshin (Elder/ Old Kai) is released. From him, Gohan is given the most incredible power up and Goku gets his life back when his son's powers are just not enough to stop Buu.
From here, Supreme Kai becomes a different character. In order to help Goku, he is instructed to use his Potara earrings and fuses with Kibito.
Sticking with the above theme, he's very nervous and anxious all of the time. Where as Rou Kaioshin will listen to music, drink coffee, fish or watch TV, Kaiobit (I prefer this name) CONSTANTLY has his face plastered to his crystal ball, engrossed in all matters pertaining to Earth. Rou Kaioshin tells Kaiobit "he knows he's a good man but he needs to learn how to relax and find a real solution to his problem." Freaking out does nothing.
In short, Kaiobit is still the same as Kaioshin but a touch..."quirkier" than the original. You'll have to see him act to know what I mean.
Kaiobit has inherited from Kibito the ability to transport anywhere in the universe that is lower than his planet; a "technique called Kai-kai." He becomes the hero when Buu (free of Fat Buu do to Vegeta and Goku) destroys the Earth and Goku is unable to transport quickly enough to save himself and the others. Kaiobit shows up just in time and stretches out to Goku and grabs his hand. Using Kai-kai, Goku, Vegeta, Dende, Mr. Satan and Bee the dog, are all rescued from the exploding planet and brought back to the Kaioshin planet.
Rou Kaioshin gets the idea that Goku and Vegeta should fight Buu on Kaioshin-kai (the Kaioshin planet). The planet is so sacred, old, and strong that not even Buu could destroy it if he tried. Rou also suggests that Kaiobit give up his shiny Potara earrings to Goku and Vegeta so they can fuse again. Goku declines and Vegeta crushes the earring, both refusing to fuse ever again. Kaiobit never does score another pair of Potaras and his ears are nekkid for the rest of the series *sniff*.
By request of Goku, Kaiobit takes everyone but Mr. Satan and Bee with him to another planet, far from the danger of Buu and his fight with Goku and Vegeta. The three gods (Kaiobit, Rou Kaioshin, and Dende) watch with concern, the battle of Buu vs. Goku and Vegeta. A while goes by and a determined Kaiobit stands up and announces that he doesn't care if he dies and can only hold off Buu for one minute; he's going back to fight Buu and help Goku. Dende soon follows suit, much to Kaiobit's delight. Rou Kaioshin though knows that both of them are far to weak to be of any real help and they are more useful right where thay are. Both decide to stay. <
After a short stay on planet unkown, Vegeta tells Kaiobit to take everyone to Planet Namek where they will collect the Dragonballs. Kaiobit does as he's told and soon himself, Rou Kaioshin, and Dende, as well as all of the nameks are on their way to three granted wishes.
And the rest is Dragonball Z history. Three wishes are made and the world is saved. Kaiobit teleports everyone back to Earth and each give him a thumbs up or a wave. None of the Kaioshin's are seen again for the rest of Dragaonball Z.
After these encounters, Kaiobit remains as a helpless by-stander. A spectator behind the eyes of his crystal ball. He always wishes he were strong enough to truly make a difference but alas, its just not in the cards.
In conclusion, Kaioshin truly made a difference in the world of Dragonball and his dedication to helping everyone is always admirable. His only reward though, is nothing at all. I think that's why we all love him.
