Compared to the other ogres, King Yemma is of a different color, he has a beard, he has a helmet with two horns, and he is colossal in size; even his desk is at least three times taller than Goku, who is able to fit in one drawer.
King Yemma is strong enough to stay in control in any situation and can easily overpower Raditz. Later in the series, when the power of the villains increases, this becomes less impressive. King Yemma is very impatient, and easily angered by the smallest of things (just like when screaming at Piccolo when he was ruining heaven), but is willing to listen to people's problems if he needs to. He also dislikes it when people hold up the line at the Check-In Station yelling at Kami to leave when he held up the line while deep in thought and even jokingly threatened to send the pure hearted Guardian to Hell just to scare him when he overheard Kami revealing to Goku that King Kai was stronger than him, showing he is not above using his position to threaten people. Though he might not seem like it, he is highly intelligent as shown when he recovered Vegeta's body and sent Dabura to heaven instead of hell. He is also good natured as was shown by his kind treatment of Goku and his tolerance of Goku's lack of manners. He also fulfilled Goku's wish that Kid Buu be reincarnated as a good person, resulting in the latter's reincarnation into Uub.
Dragon Ball Z
King Yemma appears early in Dragon Ball Z, when Goku is killed and is brought to the Other World by Kami to receive training from King Kai. Until then, King Yemma was the only person who had ever run all the way along Snake Way, but he grants Goku permission to give it a try. He is apparently skilled to some degree in fighting, as he claims he easily bested Raditz when the latter attempted to fight him while passing through his realm using his Yemma Lock. Yet, according to Kami, King Kai is much stronger than he is. King Yemma heard Kami whisper this to Goku, and threatened to send him to Hell when he dies, although in truth, he was just trying to scare him. When Kami thought to himself about all of the dangers that would come in one year, King Yemma finally lost his patience and ordered Kami to leave.
Yemma is later shocked when Goku returns from King Kai's planet and watches as Kami and the latter return to Earth. He then realized Earth did have a chance against the Saiyans.
Majin Buu Saga
In the anime filler, King Yemma sent Cell down to Hell after Gohan killed him. Later, when Demon King Dabura is killed by Majin Buu, King Yemma admits him into Heaven on the basis that he would have enjoyed himself in Hell; however, in anime filler, Dabura is shown enjoying Heaven too. Later, it is revealed that after Vegeta's death, King Yemma allowed him to keep his body and had Fortuneteller Baba bring him to Earth so he could help Goku fight Super Buu. He also got a satellite television so he could watch the fight between Goku and Kid Buu. Following the battle's climax, King Yemma overhears Goku's hope that Kid Buu will return someday as a better person so that they can have a rematch, and decides to grant Goku's wish and reincarnate Kid Buu as Uub, who goes on to be Goku's apprentice and successor.

King Yemma is working until he gets trapped in his office by Janemba by a barrier that Pikkon slowly destroys while Goku and Vegeta fight the monster. One of his workers gets frozen by the strange yellow stuff that traps them inside. Pikkon realizes that insults could destroy the barrier, but its very slow, and King Yemma gets impatient and waits for a long time (Pikkon goes down to hold off Janemba while Goku and Vegeta are fusing). Everything inside the strange yellow circle is funny, and King Yemma wants to send people to either Hell or Heaven immediately.
Other manga appearences
The mythological figure King Yemma is closely based on (the two have the same name in the Japanese version of the manga, strengthening the connection), Enma, appears in Akira Toriyama's earlier manga series, Dr. Slump, where Trampire and her servant were hired by him as grim reapers to retrieve Senbei Norimaki when he died from being hit by a coconut. Arale Norimaki manages to go with them, throws a pile of poop on him, which angers him. Enma then sends them on the way to Hell, not knowing that Arale's friend Chivil is getting them back to the living world. During the incident, Enma fires Trampire and her servant.
King Yemma is strong enough that after Raditz died and was sent to the Other World, King Yemma was able to handle Raditz with ease after he began to get rowdy. However, as Kami tells Goku he is still not as strong as King Kai.

- King Yemma is based on the Buddhist and Chinese deity . Also, King Yemma's dislike for lying is a direct reference to a Buddhist fable where the lord of death Enma will tear out a child's tongue if they lie.
- King Yemma shares similarities to King Enma from Yu Yu Hakusho in both appearance and occupation. This would be due to both being based on the same deity.

- King Yemma may be many millions of years old, as Old Kai knew of him prior to meeting him during the events of the series.
