- This article is about West Kai. For other character, see West Supreme Kai.
West Kai is short in stature, being about half the size of North Kai, and wears a blue monocle (he is the only Kai without sunglasses).
West Kai is quite arrogant, rude, and insulting. Like his fellow Kais he can be very immature when bickering with his counterparts whom he usually only gets along with during a universal crisis. He is also a very sore loser, being unwilling to lose without making up some excuse when it's obvious he lost no matter how ridiculous the excuse is.
West Kai taught Pikkon the Thunder Flash Attack (along with a fighting stance that can be utilized to enhance the technique). Additionally in Dragon Ball Z: Bojack Unbound, North Kai explains that he and the other Kais (including West Kai) use their power to seal the Galaxy Soldiers and their leader Bojack inside a star to stop their rampage.
Dragon Ball Z
Majin Buu Saga
Main articles: Other World Saga and Kid Buu Saga All four Kais often argue with each other, make fun of each other, or insult each other, but West Kai seems to particularly be North Kai's rival, and takes an immediate dislike to Goku, who is North Kai's star pupil. The only times the Kais get along is in a time of universal crisis (something that does not happen frequently).
Shortly after he is introduced, he makes fun of King Kai due to being deceased and the two constantly argue and compete using their strongest fighters. During the Other World Tournament he makes a bet with King Kai, if Pikkon wins, then King Kai is to be his slave, on the other hand if Goku wins then he is to give King Kai his home planet.
His fighters are very strong and his best and strongest fighter is Pikkon. His fighters also include Tapkar and Maraikoh. When Pikkon fried the arena twice with the Thunder Flash Attack, West Kai remarks that "I told him not to do that, 'don't use Thunder Flash unless you're far away' I said. It's getting harder and harder to teach these kids, It's all about explosions to them."
Sometime later, West Kai encounters Kid Buu, and it turns out that he fought the monster Majin Buu, as North Kai reminds him. He does not recognize Buu at first, wondering if he is training or "trying to kill us." While Goku fights Buu, he remembers the villain after North Kai mentions him, he teases Pikkon with the obvious truth that Buu is much stronger than him, much to Pikkon's dismay.
Dragon Ball GT
Shadow Dragon Saga
Main article: Shadow Dragon Saga
Years later, in Dragon Ball GT, West Kai is shown when Goku asks King Kai to persuade people across the universe to give some of their energy to form an Super Ultra Spirit Bomb. He is shown relaxing on a deck chair, still on Grand Kai's Planet.
According to Grand Kai in the film, North, East, West, and South Kai tend to only get along with each other during a crisis such as the one caused by Janemba.
According to North Kai in Bojack Unbound, he together with his fellow Kais, including West Kai, were strong enough to cast a sealing spell capable of sealing away mortals as powerful as the Galaxy Soldiers inside a star.
However, he and his fellow Kais were not strong enough to defeat the Galaxy Soldiers who as a group were strong enough to overwhelm a Super Saiyan Full Power Gohan after being freed due to North Kai's death during the Cell Games, thus explaining why they resorted to sealing them instead.
- Flight - The ability to fly using ki.
- Telepathy - Like his rival North Kai, West Kai is capable of communicating telepathically and can allow others to communicate by having them place their hand on his back.
- Far-Seeing Arts - As the Kai of the West Area, West Kai can observe events going on in the West Area and lower realms.
- Sealing Spell - In Bojack Unbound, it is revealed that together with his fellow Kais he is capable of sealing beings as powerful as the Galaxy Soldiers inside a star. However the seal eventually broke as a result of North Kai's death during the Cell Games.
- Flawless Stance - A fighting stance where the user sways their arms around their body as they produces a blue flame-like aura which West Kai taught to Pikkon to enhance the power while reducing Ki cost of Thunder Flash Attack if performed before initiating Thunder Flash Attack itself. While it went unnamed in the anime, it was later named in Dragon Ball Legends where it appears as the Special Quirk Skill Arts for Pikkon (DBL24-15S) in his Agile Style "transformation". It is unknown if West Kai himself can use the technique or like North Kai's Kaio-ken and Spirit Bomb only invented the technique and eventually found a student capable of performing it in Pikkon.
- Thunder Flash Attack - An Ultimate Attack that West Kai taught to his student Pikkon. It is unknown if West Kai himself can use the technique or like North Kai's Kaio-ken and Spirit Bomb only invented the technique and eventually found a student capable of performing it in Pikkon.

- West Kai is one of the few characters who does not die in Dragon Ball Z. Although he is not dead, during the episode "True Saiyans Fight Alone" where Kid Buu prepares to destroy Other World, West Kai can briefly be seen with a halo for a short moment.
- West Kai is never mentioned in the Dragon Ball manga, only North Kai and South Kai are seen.
- Super Pikkon can be seen wearing the West Kai's clothing in Dragon Ball Heroes and Super Dragon Ball Heroes: World Mission.
- Flawless Stance can be seen as West Kai's equivalent to North Kai's Kaio-ken (as both techniques produce flame-like auras, albeit blue in the case of Flawless Stance, red in the case of the Kaio-ken), just like how Thunder Flash Attack can be seen as West Kai's equivalent to North Kai's Spirit Bomb, as both techniques where developed by West Kai and taught to Pikkon (which resembles how the Kaio-ken & Spirit Bomb which were developed by North Kai and taught to Goku).
