Potara

The are earrings worn by Supreme Kais and their apprentices. Despite being worn so casually, they have incredible properties, allowing two individuals to fuse or permitting the wearer to use the Time Rings.
==Concept and creation==
The Potara Earrings were originally nothing but decoration, however, when Akira Toriyama wanted to introduce a fusion for Goku and Vegeta without taking away from Toei's upcoming movie at the time, he decided to introduce the concept that the Potaras were fusion items into the story.
==Overview==
These earrings are worn by all Supreme Kais as part of their standard outfits, coming in various colors. The earrings can grant the wearer certain privileges, such as using the Time Rings that are exclusive to Supreme Kais.Dragon Ball Super episode 54, "He Who is of Saiyan Blood Trunks's Resolve" The earrings also have the ability to fuse two people into a single entity for an hour, although it is permanent if a Supreme Kai is involved.Dragon Ball Super episode 66, "Showdown! The Miraculous Power of Unyielding Warriors" Only Supreme Kai are supposed to possess Potara earrings, which are signified by their distinct green color (though the anime, colored manga and games incorrectly depict them with a variety of colors).
Old Kai gives his pair to Goku as a trump card for defeating Super Buu. Shin and his attendant Kibito accidentally merge without knowing about the fusion being permanent.Daizenshuu 4, 1995
In Dragon Ball Super, Goku Black wears a green Potara earring in order to use the Time Ring in his position. The Potara Fusion is mentioned again by Gowasu and Zamasu, as Gowasu appoints him briefly to the rank of Supreme Kai by giving one of his Potara so that Zamasu could use the Time Ring. Gowasu suggests that they could fuse permanently if they wish so, but Zamasu rejects the offer. It is also revealed that if two Potara earrings are worn on the same ear, the two beings will not fuse.
Later, Future Zamasu and Goku Black fuse into Fused Zamasu using the Potara as their final trump card. Goku offers to fuse with Vegeta again, but Vegeta is initially hesitant. Gowasu then reveals that the reason why Goku and Vegeta did not stay fused the previous time is that neither of them are Supreme Kais and that fusion without a Supreme Kai would only last an hour. Vegito is born once again but defuses before even forty minutes has passed. Gowasu speculates that Vegito Blue is simply too powerful for the fusion to sustain. In the manga Fused Zamasu also defuses, as per Akira Toriyama's outline.
In the anime, before the start of the Tournament of Power, Champa and Fuwa give the Universe 6 Saiyans a pair of Potara earrings as a last resort to use. Caulifla and Kale put them on in the tournament after getting overwhelmed by Goku. They fuse and become Kefla, who then proceeds to combat Goku.Dragon Ball Super episode 114, "Bloodcurdling! The Explosive Birth of a New Super Warrior!" Kefla pushes Goku to the state of Ultra Instinct Sign and is defeated as a result.Dragon Ball Super episode 116, "Signs of a Turnabout! The Autonomous Ultra Instinct Erupts!" Rabanra and Zarbuto of Team Universe 2 attempted to perform Potara fusion as well but failed when Kefla ran over them and destroyed their earrings.
In the manga before the start of the Tournament of Power, Caulifla snatches the Potara earrings from Fuwa. Under Champa's suggestion, Caulifla fuses with Kale to stop her rampage and save her before getting eliminated by the Pride Troopers. In her new form, she easily eliminates most of them and is about to challenge both Goku and Jiren to a fight until Gohan intervenes and fights her on his own.
Interestingly, upon Good Buu awaking Grand Supreme Kai's memories and gaining the ability to transform into Grand Supreme Kai, the Grand Supreme Kai's Potara were also restored presumably by the magical properties of Good Buu's Majin body as they had been previously absorbed with Grand Supreme Kai.
During the Universe Creation Saga, Salsa provides Potara earrings to Goku & Vegeta, indicating that Salsa is a Demon Supreme Kai. Additionally, Salsa wears them on his outfit instead of his ears, with one pair attached to his hoodie while the other two are attached to the armlets he wears.
==Usage and Power==
 is a powerful Fusion technique using the Potara earrings. To perform it, two nearby individuals must be wearing a single earring, but on opposite ears. They will be automatically drawn to each other until they connect, then fuse. As shown with Shin and Kibito, the earrings do not have to be from the same set in order for this to work. Interestingly, Kibito's earring (blue in the anime) becomes the color of Shin's earring (yellow) after the fusion.Dragon Ball Z episode 266, "The Old Kai's Weapon"
If a living and a dead person fuse, the result will be living.Dragon Ball Z episode 268, "Union of Rivals" If a fused being dies, he or she will remain fused. If the earrings are removed or destroyed, nothing will happen if the fusion is permanent, but the fused being will defuse if it is temporary. If a fused being defuses, both individuals will retain the memories of the fusion, as well as some memories from the other individual.Dragon Ball Super chapter 24, "Son Goku's Evolution"
A fusion using the Potara earrings yields greater power than the Fusion Dance.Dragon Ball: Super Exciting Guide, 2009"Item Dictionary", Daizenshuu #7: "To use [the Potara], the two people who will merge simply have to each take one of the two earrings and put in on their left or right ear, respectively. Furthermore, after merging, the power is greater than with Fusion". In the anime, according to Vados, the fusion creates a new body and personality greater than the sum of the two individuals and increases their power by "tens of times." When Goku Black and Future Zamasu fused, Gowasu stated that their power did not just merge, but expanded to no end.Dragon Ball Super episode 55, "Final Judgement? The Ultimate Power of an Absolute God" Even without transforming, Kale and Caulifla's fusion, Kefla, was capable of completely outclassing the tired Super Saiyan God Goku, who stated that her energy is so massive that he could not even feel a limit. One guide referred to Vegito's power as being that of Goku and Vegeta's multiplied.
It is implied by Beerus that compatibility between the two individuals is a factor in the fusion, though it is unspecified how and to what extent; he claims Android 17 and 18 should be perfectly compatible with each other because they are twins.Dragon Ball Super episode 115, "Goku vs. Kefla! Super Saiyan Blue Beaten?"
Unlike the Fusion Dance technique, the Potara Fusion does not require the individuals to have equal power levels; the fusion lasts an hour instead of thirty minutes (unless one of the fused is a Supreme Kai, in which case the fusion is permanent); and it also fuses clothing, whereas the Fusion Dance gives the newly fused being the native dress of the people of Planet Metamor. Prior to the explanation of its hour time limit in Dragon Ball Super, the Potara Fusion was referred to in some media as supposedlyDaizenshuu 7, 1996 being permanent for anyone. There are circumstances which result in the negation of the energies involved in maintaining the fusion; such as the inner atmosphere of Majin Buu. This is re-iterated in Dragon Ball Daima, in which Shin and Kibito revealed they allowed Buu to temporarily absorb them as Kibito Kai to try and repeat Vegito's circumstances, which succeeded in their de-fusion, apparently due to a special gas within Buu that ended up reversing the merge. Whether or not Vegito defused due to Buu's inner atmosphere or because he had reached his fusion time limit is unconfirmed. At the time of Daima, Shin appeared unaware of the one-hour fusion time limit for non-Supreme Kai components, as he did not mention it to Goku.Dragon Ball Daima episode 1, "Conspiracy" However, the inner gas of a Majin will not always undo a Potara fusion, as in Dragon Ball Heroes Kid Buu was able to absorb Kibito Kai without this occurring.Dragon Ball Heroes, 2010
In some cases, such as Old Kai and Kibito Kai, one of the two fused individuals takes over the fusion's voice. In other cases, such as Vegito or Kefla, the two individuals' voices are overlaid, similar to the Fusion Dance. Fused Zamasu has two Zamasu voices on top of each other, despite one of the Zamases, Goku Black, having Goku's body and voice at the time of the fusion.
Likely due to his status as a grim reaper, Shroom's Potara Earrings operate quite differently from others. Rather than fusing with another individual, the earrings allow Shroom to assimilate the soul of the individual to further enhance his own power, similar to that of Namekian Fusion. Like the standard Potara Fusion, Shroom resembles a merged being between himself and the absorbed soul, and can take on some of the personality traits of the individual whose soul he absorbs, such as when he became "Shroosa" from absorbing Salsa and acquired a more merciful attitude, much to his chagrin.
===Weaknesses===
If fusion occurs without a Supreme Kai, the fusion only lasts an hour; this is further reduced if the fused being is so powerful that the power sustaining the fusion gets used up. In the manga, Fused Zamasu overcame this weakness by being the fusion of two of the same person.
If an individual is transformed while fusing, the fused being will not be able to power down from that transformation. As a result, certain transformations, such as Super Saiyan, can put a significant strain on the user's body and shorten his or her lifespan.Dragon Ball chapter 502, "Will the Potara Prevail?!" Fused Zamasu is permanently in the state of Super Saiyan Rosé due to Goku Black using it when he fused.
In the anime, if an immortal and a mortal were to fuse, the regeneration of the fused being from the immortality will be impaired. If the damage is sufficient enough, the body will not heal properly and will become corrupted; it is even possible for the body to be completely destroyed, as shown when Fused Zamasu destroyed his own body after Future Trunks cut it in half with his Final Hope Slash. Despite this, Fused Zamasu did not actually die and continued to exist without a body. In the manga, this does not exist.
A user of Forced Spirit Fission technique can defuse a Potara fused being by splitting and tearing apart it's fusees individual spirits into their separate original selves.  
In World Mission, Super Saiyan Xeno Vegeks defuses prematurely just as he is about to face a deranged Legendary Super Saiyan Broly. Xeno Trunks suggests it is due to his body having not fully recovered (due to him having his energy drained previously by Yamu & Spopovich's Majin Buu Resurrection technique).Super Dragon Ball Heroes: World Mission, 2019 However it should be noted that Xeno Vegeta was in his Super Saiyan 3 form when he fused with Xeno Trunks (Base) which resulted in Super Saiyan Xeno Vegeks which along with Xeno Trunks' body not being fully recovered presumably contributed to the fusion time being shortened (as his seemingly permanent Super Saiyan form may have put a strain on his body which would likely be further hampered by his fusee Xeno Trunks having yet to fully recover).
===Other abilities===
Wearing even a single Potara earring that belongs to a Supreme Kai enables one to use the Time Rings.

Xeno Goku and Xeno Vegeta fuse into Xeno Vegito once more to combat Fu and Broly. They defused an hour later.
*Fused Zamasu: Future Zamasu and Goku Black fuse into Fused Zamasu.

Or Zamas?!"

In Budokai 2, Budokai 3, and Budokai HD Collection, Shin can use the Potara Fusion and fuse with Kibito to become Kibito Kai. Goku and Vegeta both can use the Potara Fusion and fuse together to become Vegito. Also, in Budokai 2, Goku and Hercule can use the Potara Fusion and fuse together to become Gokule. In the Budokai series, Potara Fusions lack the timer seen with Fusions produced by the Fusion Dance, because at the time the games were released it was believed that Potara Fusion was permanent regardless of who used them.
In Budokai Tenkaichi 2, it features a character upgrade system that uses different "Potaras" to add special attributes to characters. These Potaras are known as "Z-Items" in the English release. A wide variety of different upgrade types are available, ranging from simple stat upgrades to powerful special abilities.
Budokai Tenkaichi 3, features the same system as Budokai Tenkaichi and Budokai Tenkaichi 2, with a new Z-Item type: the Red Potara Z-Item, which substantially increase the powers of the fighters. They have the same abilities as the other Potara Z-Items, only compacted into one usage, such as maximum damage, inflicting neutral damage with Blast 2 and Ultimate Blast attacks, recovering health quickly, surpassing limits, using half the amount of energy for ki consumption usage, and others. Characters with all "Red Potaras" equipped are also called "GOD Characters." Red Potaras can only be accessed by the player through cheat devices or by entering passwords to allow access to these characters in Duel mode, though computer-controlled characters will have Red Potaras equipped during certain matches in Story Mode or Dragon Sim mode.
In the Raging Blast series, Potara are used in the same way as in the Budokai Tenkaichi series.
In the Potara Fusion ending of Shin Budokai: using the Potara earrings (which Kibito Kai had Shenron repair), Goku and Vegeta use this to fuse back into Vegito in order to defeat Janemba and Buu before going to train in the Hyperbolic Time Chamber.
In Dragon Ball Heroes, the Potara appear in gameplay when Goku and Vegeta are about to fuse. During the Demon God Towa Saga, Xeno Vegeta and Xeno Trunks use Potara earrings given to them by Chronoa to fuse into Xeno Vegeks in order to take on Demon God Towa.
In Xenoverse, like most Supreme Kai, Chronoa wears a pair of Potara earrings, though they are never used to initiate Potara Fusion. Additionally, despite Vegito's appearance in the game, Goku and Vegeta use of the Potara Earring to fuse into him is not shown as he only appears in Parallel Quests and not in the game's main story (unlike Gotenks and Gogeta who use the Fusion Dance during the Majin Buu Saga and the 2nd half of the GT Saga). Despite Vegito's Clothes appearing as an obtainable outfit for the Future Warrior, it lacks Vegito's Potara Earrings entirely.
In Dragon Ball Fusions, male & female Offworlder characters will wear Potara Earrings if custom Face Options 1, 2, 3, or 4 (which are based on the Glind) are selected. Additionally, some non-Offworlder characters such as the Namekian Moolin wear Potara-like Earrings. Additionally, certain EX-Fusion characters like Kibeer Kai and Kibicollo Kai may wear Potara Earrings if one of fusee wears them (as Kibeer Kai is the fusion of Beerus and Kibito Kai while Kibicollo Kai is the fusion of Kibito Kai and Piccolo).
In Xenoverse 2, in addition to the Potara worn by Vegito, Chronoa, and Elder Kai, Goku Black wears one Potara earring his left ear. As part of the Super Pack 4, Vegito Blue and Fused Zamasu appear as DLC characters.
In FighterZ, the Potara earring fusion features in both Vegito and Kefla's intros, showing the fusers in both cases (Goku and Vegeta in the former, and Kale and Caulifla in the latter) with earrings equipped before the fusion occurs, though only in Kefla's victory animation is a Potara fusion seen wearing off, as Kefla runs out of fusion time mid victory jump, causing Kale and Caulifla to crash to the ground.
In World Mission, during Chapter 3, Sub Chapter 4: "Legendary Super Saiyan Awakened", Chronoa gives Xeno Goku Potara earrings should he, Xeno Vegeta, and the Dragon Ball Heroes encounter serious resistance while protecting Hero Town. They are then used by Xeno Trunks and Super Saiyan 3 Xeno Vegeta to create Super Saiyan Xeno Vegeks who makes quick work of Xeno Janemba. Additionally, Potara are used to represent certain types of Accessories such as CAA/TAA Special Ability and Ultimate Units which can be equipped to any card's (official or custom) Potara Accessory slot in a Custom Deck. Only one Potara Accessory can be equipped to the slot. Equipping a CAA/TAA Ability Accessory will replace the card's default CAA/TAA Ability with that of the Accessory in question. Additionally any Accessory that grants Fuse type Special Abilities (Absorption, Fusion Dance, Potara Fusion, Infestation, etc.) can only be equipped via the Custom Deck (as they cannot be equipped to custom cards created via Card Creation) and the Accessory must be equipped to at least two cards to use in battle, which requires the player to have at least two of every Fuse-type Accessory.
==Trivia==
*Several characters in the franchise wear earrings similar in style to the Potara. Among them are Zarbon, a man bearing the same symbols as Nok in the audience of the 28th World Martial Arts Tournament, Don Kee, and the Demons Towa from Dragon Ball Online and Dragon Ball Xenoverse, and Demigra from Xenoverse and Dragon Ball Heroes.
**In Dragon Ball Fusions, certain characters like Moolin wear Potara-like earrings. Offworlder Tekka can be customized to wear Potara (as both Glind and Majin are considered part of the Offworlder race).
**In the Victory Mission manga, Beat's Mom wears Potara-like earrings.
**During the Universe Creation Saga, Salsa's earrings are revealed to be Potara, indicating he is a Demon Supreme Kai. 
*In Dragon Ball Fusions, it is shown that it is possible for a Glind-based Potara fusion like Kibito Kai to perform EX-Fusion. Presumably, this is due to the normally permanent nature of said fusion.
**Additionally, both Kibito Kai and Vegito can perform Five-Way Fusion as well.
*Kefla is the first female Potara Fusion to appear in the entire Dragon Ball franchise. She is also the first female Potara Fusion who is pure Saiyan and the second pure Saiyan Potara fusion after Vegito.
*Beerus' assertion that twins like Androids 17 & 18 are perfectly compatible for Potara Fusion is interesting and ironic as Beerus himself has a twin, his brother Champa.
**Conversely, the same could be said of Beerus & Champa as they would likely have similar compatibility as both are twin brothers & Gods of Destruction. Though given their sibling rivalry it is unlikely they would agree to perform Potara fusion under normal circumstances.
