Minus Energy

is a form of dark energy that exists throughout the multiverse. This energy can be created from negative emotions like hate, greed, and jealousy. While the threat of Minus Energy is usually negligible when the universe is at peace, sudden increases in Minus Energy as a result of negative experiences and concentrations of negative emotions can result in the creation of Minus Energy Monsters, a unique class of Kaiju whose existence is intertwined with that of the energy itself.
==History==
===Ultraman 80===
Minus Energy is said to be the main reason behind the existence of monster attacks. Ultraman 80 arrived on Earth to study and curb the rising monster attacks by guiding the young generations to the right path. He does this by assuming the human form of Takeshi Yamato and attending the Sakuragaoka Middle School as its first year teacher. True to Yamato's claim, a new resurgence of monster attacks occur, starting from the appearance of Crescent, who Yamato claimed to have been manifested from the surplus Minus Energy building up from the long period of peace since the last monster attack in 1975. Since then, several few more monster attacks started to occur, some of which strangely related to his students, but Yamato/80 fought against them, as well as solving the issues of each students in their daily problems. Eventually, Yamato had to resign as a teacher at one point to fully commit to his work as a UGM officer, especially when the monster attacks started to become frequent even if the Minus Energy rarely see its spotlight.
===Heisei Ultraseven===
Banderas, the parent star of a distant solar system, formulates a plan where he will travel to Earth to use the Minus Energy from mankind to prevent him from dying. After constructing himself a humanoid form, Banderas travelled to Earth, using his gold-manipulating powers to take advantage of humanity's innate greed to obtain Minus Energy from the people of Miyanishi Village, at the same time enslaving them as his mind-controlled subordinates.
When the Ultra Guard came to investigate, Banderas revealed himself and proposes the idea of absorbing mankind's Minus Energy, in return promising to grant peace and prosperity to Earth. TDF's top brass, especially Shigeru Furuhashi, opposed the idea and ordered Ultra Guard to quickly foil Banderas' scheme, especially when Seven exposed that Banderas's own solar system is no longer habitable. 
While not exactly Minus Energy itself, hatred and phobia became an element during the emergence of Neo Pandon. The control system used by Suwa to manipulate Neo Pandon harnesses the user's hate and fear to fight and commence attack, but peaceful intentions such as Mitsuko's will turned the monster docile. Suwa originally forced the monster to attack the Ultra Guard members but was forced to hand over the device to Mitsuko when she decided to stop their conflict. A misunderstood Keisuke Shima grabbed the device without knowing the purpose and his phobia towards Mitsuko on an unfounded pretext that she is an invader brought Neo Pandon back to its rampaging directive before he shoots her. Kazamori/Seven killed the Neo Pandon afterwards, leaving the scene with a new seed for another Plant Life form to grow. The rest of the Ultra Guard discover the true nature of this incident too late, berating Shima for his recklessness playing a part in escalating the conflict even further. 
===Ultraman Dyna===
To empower Menorfa, Alien Naltis requires Minus Energy from humans as her race is devoid of conflict. Among her targets are the Roller Kids, a group of delinquents which Sonoka Hibiki (daughter of Super GUTS captain Gousuke Hibiki) is a part of. The delinquents drained of their Minus Energy became obedient students in return, but Hibiki himself attest that one's negativity is part of themselves. When Naltis and Menorfa are killed by Ultraman Dyna, the Minus Energies return to their respective owners, hence restoring the Roller Kids. 
===Ultraman Mebius===
Continuing from 80's past service on Earth, Yamato admitted to Mirai that his effort at curbing the Minus Energy activity on Earth went off the rails when his resignation from being a teacher means that he failed to uphold his initial promise to just fighting monster attacks. The Sakuragaoka Middle School was about to be demolished, but wishing to see Yamato one last time, it generates Minus Energy to create Hoe once more. The monster manages to weaken Mebius until 80's arrival, by that point Hoe actually fulfills its goal and willingly allowed itself to be purified by the Buckle Beam and disappear. The Sakuragaoka Middle School got its wish and Yamato was greeted by his former students in a heartfelt reunion. 
===Ultraman Zero: The Revenge of Belial===
Minus Energy was discovered to be the fuel used to empower a trio of Darklops units during their attack on the Land of Light. As an expert in studying this energy substance, 80's knowledge led to the discovery that the robots came from an alternate universe (the Another Space) and therefore setting forth Ultraman Zero's journey to that dimension to get to the bottom of this incident and eventually leading to his encounter with the Belial Galactic Empire. 
===Ultraman Saga===
While not actually appearing in the film, episode 35 of Ultraman Retsuden served as a prologue, revealing that Zoffy had sensed a Minus Energy of a Zetton coming from another dimension (the Future Earth) before he reported it to Zero, hoping for the young Ultra to be careful. This gives off the implication that the Alien Bat of Future Earth's constant experimentation with his Hyper Zetton gives off strong Minus Energy reaction, so much so that it can be felt even from another universe. 
===Ultraman Ginga===
After the events of Dark Spark War rendering him weakened, Dark Lugiel uses Kyoko Shirai as a cover and had his minions to distribute the Dark Dummy Spark among the former students of Furuhoshi Elementary School. Constant using of Spark Dolls to Dark Live and performing acts of atrocity allows Lugiel to feed on their Minus Energy and gradually restoring him to full strength. 
===Ultra Fight Victory===
Yapool (in Giant Yapool form) himself is revealed to have his own supply of Minus Energy in his own body. After being defeated by Ultraman Gingavictory, he allowed the Minus Energy from his destruction to reach the space distortion on Planet Gua and became the final push to resurrect Juda into Juda Spectre. 
===Ultraman Orb===
A psychic girl named Haruka Kirishima has the ability to see the future, but her inability to prevent bad futures from happening caused her to fall into despair. This created an enormous amount of Minus Energy over time and eventually leading to the creation of Hoe, as Gai Kurenai pointed out. But once Haruka is able to warn Ultraman Orb of the monster's sneak attack, she regains confidence in her powers and as such, Hoe's destruction becomes permanent. 
===Ultra Galaxy Fight: New Generation Heroes===
, where the League of Darkness set up their base of operations, is said to contain a high concentration of Minus Energy. 
==Powers==
*Monster Creation: Large amounts of Minus Energy is able to create monsters. Sometimes the created monster would use a physical medium as a vessel, as seen with Guwaganda and Delusion Ultraseven, which were respectively created from a stag beetle carcass and an Ultraseven action figure.
**Monster Attraction: Other than creation, it can also summon space monsters to Earth, with Gikogilar as an example. Those who were summoned to Earth are also designated as Minus Energy Monsters in the same way as the ones purely created by said energy substance.
*Empowerment: Minus Energy is able to be used to empower other beings.
*Corruption: Minus Energy itself can act as a corrupting agent. A small space creature named Jacky turned hostile as a result of exposure to Minus Energy on Earth and in turn mutated an elephant into Zuruzla after being swallowed by accident.
==Derivatives and other similar cases==
While not explicitly stated to be Minus Energy, there are other cases in Ultraman Series where the concept of negativity is used in the involvement of an Ultra Kaiju.
===Grudges of past Ultra Kaiju===
*The Despotic Monster Tyrant was born from the grudges of seven monsters who the Ultra Brothers had fought against, prior to Ultraman Taro's arrival on Earth.
**EX Tyrant's skeletal form, EX Tyrant (Deathborn), is also a result of tapping into the full potential of its grudges to the extreme, now allowing it to use attacks related to monster grudges.
* In the Ultra Super Fight episode "Nightmare!? Duel of Man and Seven?", the Delusion Ultraseven who Ultraman fights describes himself as being formed from the hatred of monsters and aliens previously defeated by the Ultras, with Minus Energy not being mentioned at all. This is an unusual case, in that Delusion Ultraseven's debut in 80 firmly establishes him to be a Minus Energy entity, implying that this Delusion Ultraseven is a separate individual to the original.
*Phantom-Ultraman Agul was created by Queen Mezard as her reinforcement in fighting against Ultraman Gaia. Despite being claimed by the Queen as the manifestation of the deceased Earth monsters that GUARD had killed through their underground missiles, nothing had ever really confirmed this statement to be true, as the Mezards (and by extension, Radical Destruction Bringer) had a history of inducing psychological attack to their victims, particularly to Fujimiya in misleading him into antagonizing mankind.
*The same case as Tyrant is Ultra Dark-Killer, who was initially defeated by the six Ultra Brothers when they focused their energy to Taro to perform the Super Ultra Dynamite. Dark-Killer returned again through his long standing grudge against the Ultra Brothers, having resurrected Dark Lugiel and Etelgar as well to assist him in his fight against the New Generation Heroes. When he gets defeated by Ginga Strium, the latter noted that Dark-Killer will never return to life ever again, presumably disabling him of his self resurrection ability.
*According to Alien Bat Gurashie, the Tector Gear Hatred that he crafted and forced onto Ultraman Zero was created from the grudging spirits of the deceased monsters in the Monster Graveyard.
===Ultraman Cosmos===
As the series Ultraman Cosmos focus on the concept of promoting peace between humans and monsters, it also explores the concept of negativity to a smaller extent.
*The show's main antagonist, Chaos Header, is able to possess monsters and turn them into Chaos Monsters in return, causing the victims to go berserk. Having encountered Akane Tachibana and seeing her resentment for her friends manifested into Chaos Jirak, Chaos Header started to experiment on human emotion, one such example had them kidnapping Ryoichi Kano. The first Materialized Chaos Header, Evelease, was born from the emotion of hate that when Ryoichi reunited with his son, his familial love stunned the monster long enough for Cosmos to defeat him for good. Eventually in the final arc of the series, their resentment for Cosmos reached its boiling point that it eventually granted the entity its Chaos Darkness form. It took the effort of Miracluna Mode and the roars of Lidorias, Mogrudon and Bolgils to purify Chaos Darkness and eventually dispels its hate, turning it into Chaos Header 0 as a result.
*Geshot the Bronze Demon was an item from outer space which has the ability absorb stresses, but by gradually building up the absorbed stress energy within itself, Geshot will grow big and becomes a rampaging statue monster. During its reawakening in the present day, it also displays the ability to induce stresses into its targets and is later defeated by Ultraman Cosmos after exhausting the bronze giant from its stress energy.
*Renki was an onryo samurai that came to exist after the souls of star-crossed lovers failed to pass on to the afterlife, their grievances over their misfortune manifested into this monster.
*Angrilla was a monster born from Alien Migelon Reda, whose grief over the loss of his girlfriend Reka caused him to manifest the monster on his own while he intruded Team EYES' headquarters in Treasure Base. Reka's spirit was able to convince Reda into giving up on his revenge, causing Angrilla to stop and for Cosmos to use Full Moon Rect to eliminate the monster.
===Yapool's grudge===
Although Yapool himself has his own supply of Minus Energy, he is also a famous example of his own hatred manifesting into its own power. As he specifically proclaims to Sakuya, for as long as his hatred towards Ultra Warriors in general remains, then he can simply resurrect himself back to life. This has become prevalent in multiple media of Ultraman Series, as despite his constant defeat by the Ultras of that series, he is able to return and resume his endless crusade against the Ultras.
During Ultraman Z's active period on Earth, Yapool's grudge is able to manifest portals and recreate Baraba without the necessities of fusing two different creatures (a space monster with a swallowtail butterfly), allowing him to continue to carry out his plans even during the time between death and resurrection. As such, Baraba acts accordingly to Yapool's blind hatred for Ultraman Ace and is capable of speech, reiterating Yapool's goals during the fight. 
:;Non-canon media
In a particular stage show on 2020, Yapool proclaims that all of his Terrible Monsters and other creations share his grudges, which allows him to perceive their fights against the New Generation Heroes over the years. This allows him to create an upgraded variant of Victory Killer, called Ultimate Killer, who has all the memories of past New Generation Heroes' powers in addition to its preexisting abilities. 
When reviewing Yapool's exploits and fights via Ediom, Yuka Ohta acknowledges the dangerous potential that the Extradimensional Being poses and notes that due to his immortality, it means that the Ultras might possibly be locked in an unending fight with him for a very long time. 
===Unsorted===
*The Red Sphere is a sentient wish-granting object, which can also manifest monsters. When used by Kashimada and his group of bullies, the Red Sphere amplifies his resentment for being ridiculed as an Ultraman Series fan and manifested King of Mons, causing the Sphere to change into a spiked ball-like form. When Yu Hirama hold the Red Sphere, its own influence also corrupted him, allowing the monster to spawn Basiliss and Sculla. 
*From the Ultra N Project, the Space Beasts are space monsters feeding on the fears of humankind. They are also empowered by the emotion of fear, allowing a Beast Factor in the nearest vicinity to form a Space Beast if left unchecked.
*A machine created by the Visitors, Lethe functions by absorbing the memories of the Space Beast attack to help the TLT in hiding their presence from the general population. Nagi Saijyo, a Night Raider officer with massive hatred the Beasts, received the baton of Dunamist from Ren, but this allowed Dark Zagi to resurrect himself when the silver Ultra was captured by Lethe, who absorbed the giant's light and Nagi's hatred to reform the dark Ultra's own body. 
*Ultraman Belial's Belial Virus has the ability to corrupt individuals. One particular victim, Mirror Knight, also turned depressive and shunned himself into the Two-Dimensional People's home world until Zero cleanses him of the Belial Virus.
*The Eteldummies are created by Etelgar using the power of Etel Image to probe the fears of his target and bring them to life. The size of an Eteldummy is dependable on the amount of fear he was able to extract.
*Greeza's Dark Thunder Energy functions by striking monsters on Earth, empowering them into mindless berserkers. In the case of already evil beings like Mold and Gina, it gave them further empowerment without the drawback of losing their sense of selves.
*The Dark Ring is an antithesis to the Orb Ring. A sentient device, it allows its user to materialize Kaiju Cards to summon their respective Ultra Kaiju and empowers itself through its user, those who it acknowledge for having the most evil heart in the universe.
*Renki (Gurenki) is born in the same way as his original Ultraman Cosmos incarnation. While sealed in a stone slab and granting women wishes to find their significant others, Naomi's jealousy for her friend allowed Renki to be unsealed. The ghostly samurai was stopped in his reign of terror when Naomi acknowledged the errors of her ways, as well as reminding Renki of how despite his misfortunes, he was able to grant others happiness.
==Trivia==
*The monsters in SSSS.GRIDMAN which Akane Shinjo created used the Kaiju Seeds as its core and responds to her daily grievances against Gridman and those who wronged her. This in a way makes it similar cases to the symptoms of Minus Energy and the monster attacks born from it.
