Before the events of the Dragon Ball manga, the Ox-King was a martial artist who trained with Grandpa Son Gohan under Master Roshi. According to Master Roshi, the Ox-King and Grandpa Gohan did milk deliveries as part of their training, just like Goku and Kuririn did after them. Sometime after completing his training under Master Roshi, Ox-King married an unnamed wife and became ruler of Fire Mountain. The Ox-King's wife gave birth to a daughter named Chi-Chi, but then died of an illness. His unnamed wife's wedding dress would eventually be given to Chi-Chi when she married Son Goku.
Despite his threatening sounding name, Ox-King is really quite harmless and fun loving. He was somewhat demonic when his castle became engulfed in flames on Fire Mountain during a picnic with his daughter, and wreaked havoc through the village at the foot of the mountain.
In the anime, he has a few large roles though from time to time, mainly involving keeping his daughter out of trouble. He also cares deeply for his family, buying his grandchildren presents and visiting quite often, and will stop at nothing to make sure things are done, such as protecting Chi-Chi's wedding gown from the fires surrounding his castle.
Though generally very polite and generally disinterested in girls, Ox-King is shown to have a perverted side similar to Master Roshi's when watching Maron sunbathe in the episode "Krillin's Proposal". The Ox-King is a smoker, as seen on the cover of the chapter "An Unexpected Strength", in the first Dragon Ball Z opening, and in the episode "Gohan Goes Bananas!" In an interview, Akira Toriyama stated that the best cooks in the Dragon Ball universe are Ox-King and Yamcha.
Ox-King is quite large, and has a lot of facial hair. His appearance is one of the most changing of all the supporting characters in the series. When he first appears, he is drawn more barbaric and menacing, and wields an axe. By the end of Dragon Ball and beginning of Dragon Ball Z, he dresses in normal attire and wears glasses instead of goggles. His facial hair is more detailed. In Future Trunks' timeline, he appears the same except now sporting gray hair and a new outfit.
In the Kid Buu Saga, he appears to be much bigger, his facial hair grows out more, and the hair in the back of his head extends out a little over his shoulders. There are also slight alterations to his clothes. In Dragon Ball Z: Battle of Gods, he wears a blue jean and dark tanktop with a tie. At the end of Dragon Ball Z, his hair is gray and he wears formal clothes with an orange tie.
In his very first appearance in Dragon Ball GT, his tie is purple, and in his next appearance, it is yellow. Overall, Ox-King's character design changes more than any of the other supporting characters such as Puar, Oolong, Yajirobe, etc.
Ox-King is the type who relies on power more than techniques. He can not use the Kamehameha because he was not quite good enough to master it. In the movie pamphlet for Dragon Ball Z: The Tree of Might and Dragon Ball Z: The Anime Adventure Game, Ox-King's power level is stated to be 900.

Dragon Ball (Anime)
Emperor Pilaf arc
Living on Fire Mountain, Ox-King would either scare away or eat anything that came along, due to the fact that his castle was stuck up on the mountain in eternal flames, which angered him greatly. This leads residents in the surrounding area to nickname him "The Emperor of Demons". Bulma, Goku and Oolong stumble upon him and Chi-Chi on their quest for the Dragon Balls. Ox-King first finds Bulma and Oolong wandering around Fire Mountain. After Bulma convinces him they are not enemies, he asks Son Goku to find his daughter Chi-Chi who has not returned after she went looking for his old Master, Roshi, to help put out the fire. They agree to help him, and Goku along with Chi-Chi bring back Master Roshi, the only one strong enough to break the barrier. Master Roshi fires a MAX Power Kamehameha at the wall of fire, and destroys it. However, the Kamehameha is so powerful that it takes the entire mountain with it. After Master Roshi blows the mountain and castle away, the Ox-King promises not to hurt anyone again. Although his castle is gone, Ox-King and Chi-Chi shrug it off and vow to build a new one. After Goku finds Chi-Chi and returns her to her father, Ox-King offers her to Goku as a wife in gratitude of her safe return. Not knowing what a wife is, Goku agrees.
Red Ribbon Army arc
When Chi-Chi starts to miss Son Goku in an anime filler, she and the Ox-King talk to an old lady who says that he is coming. The Ox-King throws a rock at a pterodactyl (who ate a Dragon Ball) for the wedding dinner of Goku and Chi-Chi. When Emperor Pilaf comes to Ox-King's village, Shu poses as Goku. Then, Colonel Silver and the Red Ribbon Army come and attacks the Ox-King's village.
King Piccolo arc
Four years later Ox-King and Chi-Chi reappear in the anime filler, where they are seen watching King Piccolo on TV. Later, while on his way to King Castle, Goku spots some of King Furry's guards attempting to kill Ox-King on King Piccolo's orders to kill all well-known martial artists, him being the first on the list. Goku puts a stop to it and heads off to stop King Piccolo. Later on they are seen outside, watching the celebration fireworks after King Piccolo is killed.
Piccolo Jr. arc
Again in the anime filler, three years later, Chi-Chi returns to Ox-King's castle with Goku. Chi-Chi announces she and Goku are getting married, which surprises Ox-King since he thought she was just going to tell him what the Tournament was like. Ox-King is eventually trapped in his own castle after they are once again engulfed in flames, and he vows to protect Chi-Chi's wedding dress from the flames. Goku and Chi-Chi first go to find the Bansho Fan to help put the flames out but they did not succeed in stopping the flames. Fortuneteller Baba then told them about the Furnace of Eight Divisions, a part of Other World which was the cause of the flames. Goku and Chi-Chi manage to repair the holes in the Furnace, which narrowly saves Ox-King. Sometime over the three years between the King Piccolo Saga and Piccolo Jr. Saga, Ox-King seemingly gives up being a warrior and also abandons his old armor towards the end of Dragon Ball, for the look he would have for most of Dragon Ball Z. The Ox-King also becomes noticeably friendlier during this time.
Dragon Ball Z (Anime)
Ox-King originally wanted to name Son Goku and Chi-Chi's first child, Son Gohan, from a long list of names that all had "Ox" in them: "Ox-King Jr.", "Ox-Monkey", "Ox In The Box", "Big-Ox", "Oxford", "Ox-Man", or "Johnny-Ox-Seed". Gohan followed every one of these suggestions with crying. Chi-Chi then yelled at Goku for wanting to go fishing without coming up with at least one name. While yelling at Goku, Chi-Chi says the name of Goku's late adopted grandfather, Gohan. Gohan laughed each time he heard the name, and Ox-King notices this. He interrupts Chi-Chi's yelling to make Gohan's laughing be known to his parents. Goku and Chi-Chi both accept his name idea.
Ox-King visits Chi-Chi to bring presents for Gohan, who was training under Piccolo after Raditz's arrival and Goku's death. Krillin visits them and spend the night with them, but unable to break the news, he returns to Kame House. Ox-King then goes with Chi-Chi to Kame House where Roshi tells them what happened.
One year later, Ox-King returns to Kame House to witness the battle against the Saiyans on Fortuneteller Baba's Crystal Ball.
Cell Games arc
Ox-King watches the battle against Cell on TV at Chi-Chi's house. When the TV breaks, Chi-Chi breaks down and angrily berates Goku for having Gohan fight Cell, causing Ox-King to sternly remind Chi-Chi of how much Gohan had grown and that he is capable of defeating Cell and saving the planet, thanks to Goku's help. This however, just enrages Chi-Chi even further, and she begins trashing her living room- even going so far as to break her T.V. Some time later, Baba comes to the house and they watch the fight on Baba's Crystal Ball.
After the Cell Games and Goku's death, Ox-King often helps sneak Gohan out from his studies. He proudly boasts at the time that his grandson is "the strongest guy in the world".
The World Tournament arc
Seven years after the defeat of Cell, Ox-King has another grandson named Goten, who was born shortly after the Cell Games. When Goku is to return to Earth for one day, Ox-King attends the 25th World Martial Arts Tournament to cheer on his family and friends.
When Vegeta kills a massive number of people at the World Tournament stadium to get Goku to fight him, Ox-King goes with the group to gather the Dragon Balls. Ox-King takes refuge at Kami's Lookout, where he and the others learn of the monster Majin Buu and the deaths of Vegeta and Gohan (the latter of whom was actually with Supreme Kai and Kibito on their planet). Hearing the tragic news makes Chi-Chi faint. Ox-King keeps watch over her until she recovers.
A day later, Super Buu finds the tower and allows them to live for a short time. Ox-King attempts to keep Chi-Chi away from fighting Buu, but fails when she is turned to an egg and smashed. Ox-King is then one of the characters who accompany Krillin and Dende when they decide to follow Buu and Piccolo to the Hyperbolic Time Chamber. When Super Buu escapes from the Hyperbolic Time Chamber after Piccolo destroys the door, he turns Ox-King and the rest of the group into chocolate with his Chocolate Beam and eats them, thus killing them.
Kid Buu & Uub arc
Later, the destroyed Earth and all its people are revived and Ox-King give some of his energy to help Goku make the Spirit Bomb to destroy Kid Buu. He later watches as his daughter Chi-Chi hugs Goku after she is finally reunited with him. At the end of the Dragon Ball Z series, he attends the 28th World Martial Arts Tournament to cheer on his Great Granddaughter Pan.
Dragon Ball Super (Anime)
Battle of Gods arc
Ox-King becomes poor after the fire in Fire Mountain burned his treasure. Without his treasure, he is unable to support Chi-Chi and Goku which makes Chi-Chi tell Goku to get a job.
He later joins everyone at Bulma's birthday party on her cruise liner. He is shown socializing with everybody around the ship. He also serves as a waiter of sorts, helping out by serving food and drinks to people. Like Roshi and Oolong, he also looks at nude magazines. When Beerus arrives at Earth, Ox-King joins the small crowd of people watching Beerus eat the food Kuririn serves him. Unlike many others, he chooses to stay with a few other people on the ship, while Bulma gathers nearly everybody in her space-pod to go in for a closer look at Goku and Beerus' fight.
Universe 6 Arc
Ox-King attends the Universe 6 and 7 Gods of Destruction Selection Martial Arts Competition with his family and friends. After nearly three hours of traveling from Earth to Beerus' planet, and from Beerus' planet to their destination, the Nameless Planet, they finally arrive there. Ox-King is a bystander and he watches the matches between Universe 7 and Universe 6.
Dragon Ball GT (Anime)
In Dragon Ball GT, the Ox-King no longer appears to visit Goku's family as regularly as he did before, or maintain his role of calming Chi-Chi down, which is now done mostly by Videl. He was apparently possessed by Baby, along with the entire population of Earth, during the Baby Saga. He only makes cameo appearances in episodes 31, "Collapse From Within" and 40, "Piccolo's Decision", when the Baby-threat ends. From the 4th GT ending credits, Ox-King appears to be the tallest character; even taller than Piccolo and Majin Buu. He also appears in one of the final flashbacks; it shows the scene when Bulma, Oolong and Goku first meet Ox-King.

- The armor Ox-King wears in his first appearance resembles that worn by Chinese soldiers during the Ming and Qing Dynasties. The Bear Thief, the Tiger Thief, the nameless warrior from "Terror and Plague", Sky Dragon, and Lord Yao also wear similar-looking uniform.
- Though Ox-King's age is never revealed, it can be assumed that he is in his early sixties by the time the Buu Saga takes place. His hair is naturally orangish-brown when he first appears, but gradually gets darker as the series progresses to the point of being black up until the end of Dragon Ball Z, where it finally starts to gray (the special Yo! Son Goku and His Friends Return!! and the movie Battle of Gods appear to show this transition, as his hair is no longer black, but a light brownish/gray-like color). By the time Dragon Ball GT begins, he is supposedly over 70 years old (80 in the English version due to it taking place ten years instead of five after DBZ) and still living, shown by his minor appearances in two Dragon Ball GT episodes as well as other promotional works.
- The Ox-King is the only known human character, other than Master Roshi, to live four generations in the series, being alive during the lives of his daughter, grandsons, and great-granddaughter.
- Ox-King's height keeps changing constantly. One example would be when they summoned Shenron in the Buu saga, in some scenes it shows everyone up to his stomach, but in others they only seem to be as big as his knee.
