Thor (Old Norse: Þórr), also known as Thor Odinson, is the red-haired son of Odin and Jord, and is the god of lighting, thunder, storms, sacred groves and trees in Norse mythology and Germanic paganism. Thor is one of the most powerful gods and uses his superior power to protect Asgard and Midgard. Due to his lust for battle and incredible prowess, Thor is also portrayed as a war god and also an agricultural god due to his status as a weather deity that aids in the growth of crops. His belt Mejingjard doubles his strength and lightning flashes every time he throws his trusty hammer, Mjölnir.
Most surviving stories relating to Germanic mythology either mention Thor or center on Thor's exploits. Thor was a much revered god of the ancient Germanic people from at least the earliest surviving written accounts of the indigenous Germanic tribes to over a thousand years later in the late Viking Age. Thor was very talented at slaying the Jotuns; many of his stories revolve around violent episodes between him and his enemies. One of his exploits, includes his relentless slaughter of his foes and fierce battles with the monstrous serpent, Jormungandr, and his foretold death by succumbing to its venom, during the events of Ragnarök are recorded throughout sources in Norse mythology.
Thor was appealed to for protection on numerous objects found from various Germanic tribes. Miniature replicas of Mjölnir, the weapon of Thor, became a defiant symbol of Norse paganism during the Christianization of Scandinavia. Casting molds have been found for the production of both Thor's hammers and Christian crucifixes, and at least one example of a combined crucifix and hammer has been discovered.
"Origin: Scandinavia. The Aesir thunder god of Norse mythology. He rides a chariot pulled by two goats, and wields the hammer Mjolnir. He also wears the belt Megingjoro and iron gloves called Jarngreipr. He is the god of lightning and thunder, as well as fertility. At Ragnarok, he will defeat Jormungandr, but will succumb to its venom."

Thorman is the American ambassador to Japan. He requests the aid of the protagonist in defeating Gotou to prevent the demons from overrunning the Earth.
Later in the story, he reveals himself to be the demon Thor, an agent of YHVH dedicated to the ideal of the Thousand Year Kingdom. He was sent to Earth after discovering that Gotou discovered a way of summoning demons from the Expanse to the human's realm and was tasked with stopping him.
In the Law route, Thor congratulates the protagonist for aiding him in the purification of Tokyo. In the Neutral and Chaos route, he fights the party. Regardless of the options, it is too late to save Tokyo from the "Hammer of Thor," a cluster of nuclear ICBMs used to purge the demons. With this, Japan is completely obliterated.
Thor is found in Ikebukuro as a member of the Mantra Army. He is first seen when he knocks Isamu Nitta unconscious with his hammer. He locks both Isamu and the Demi-fiend up, and they must prove their strength to become free. Thor is defeated by the Demi-fiend and allowed free. After the Nightmare System destroys the Mantra Army, Thor admits that their fear-based society had no hope of creating a new world. He allows Isamu to go free, and then says that he will see the Demi-fiend again if he is truly strong. He does indeed cross paths with the Demi-fiend again on the 418th floor of the Tower of Kagutsuchi. Regardless of the Demi-fiend's Reason, Thor tests the Demi-fiend's abilities again. Thor is overwhelmed and dies at that spot.
Thor appears as the boss of Shibuya's Celu Tower gold-level instance. By defeating him, players have a chance to obtain the Ving-Thor, which they can turn in to the old man NPC in front of the boss room to obtain the ability to fuse him. Thor is a special triple fusion of Odin, Loki and Dwarf. He can be summoned temporarily onto the field when a player has an Odin and Loki within their COMP and a full fusion gauge. He also appears as a boss within the Shinagawa Diaspora instance as one of the two key-bearing mobs players must defeat in order to summon Metatron. His weapon Mjolnir and his cloak can be obtained as player equipment.
Thor takes the form of a human called "Hunter Kyuzou" in the Challenge QuestSave the Old Man. He sends a request to protect an old hunter from his enemies. After accepting the quest, Flynn is caught in a misunderstanding and ends up facing other hunters who had gone there to help the old man. Finally, a hunter wearing a cloak covering his entire body appears, only to throw it away and reveal his real identity as the Kishin Thor. He immediately attacks the hunters. However, after being put in a disadvantage, a majestic voice stops the battle. It turns out that the old hunter was actually an amnesiac Odin, and Thor made him watch those battles to make him recover his memories through the excitation of combat. Thor returns to Asgard alongside his lord.
Thorman is briefly mentioned again having died of heart failure at the age of 68. He had apparently respected Japan and was fostering friendship between the two countries after he became ambassador.
"The Norse god of thunder. He wields Mjolnir, a hammer that returns to its owner after being thrown. It is said he and the World Serpent Jormungandr will kill each other at Ragnarok."
—Devil Summoner: Soul Hackers 3DS compendium
In the 3DS remake, a variant of Thor is unlocked by Nemechi's female angel form and costs 500 D-Souls. His artwork is based on his appearance from Shin Megami Tensei III: Nocturne. While the normal version of Thor is level 59, this variant is much more powerful and at a much higher level at Level 72, making it the highest level Kishin demon in the remake, just exceeding Marici by one level.
When he is fused with any kind of Nihil weapon, he produces the weapon Mjolnir, his iconic hammer.
"A stone hammer with holy powers."
Mjolnir has an attack value of 340 while having a hit rate of 80. It strengthens Electricity attacks as if the bearer has Elec Boost. It deals Electricity damage when the protagonist attacks with it instead of Strike damage.
"The Norse thunder god and son of Odin, Thor owns the power enhancing belt, Megingjard, and wields Mjolnir, a hammer that causes lightning to strike and returns to its owner after thrown."
—Persona 5 background
Thor is the ninth Persona of the Chariot Arcana and can be found as a Shadow in the Battle Arena of Niijima's Palace and the Depths of Mementos, with the title "Thunder Emperor." He is the first Persona to learn the Elec Amp skill and one of four Personas to learn the Heat Up skill. When itemized using an Electric Chair execution in the Velvet Room, Thor will produce the Mjolnir bludgeon for Ryuji Sakamoto, which has 254 ATK, 88 ACC and adds the Elec Boost effect to Ryuji (does not stack with the Elec Boost skill). Thor is an ingredient for the advanced fusion recipe to summon Chi You.
When fought in the Battle Arena, the "Thunder Emperor" lacks his usual weakness to Psy skills in this battle and will alternate between using Charge and Concentrate before attacking with Physical or Electricity skills respectively. However, there will be an extra turn spent between the charging skill and Thor's attacks, allowing the protagonist to prepare for the attacks. Personas like Girimehkala and Rangda can repel his Physical attacks back at him for additional damage (however, Rangda is naturally weak to Electricity as well), but trying to repel Thor's Electricity attacks will result in the damage being nullified.
"The Norse god of thunder and fertility, whose strength is incomparable. He is a heroic and honest god. He is worshiped mainly by farmers and is most known for defeating giants. He wields Mjolnir, a hammer which returns to its owner after being thrown. He and the World Serpent, Jormungandr, are fated to kill each other at Ragnarok."
"The Norse god of thunder. Later known as the god of agriculture, he was worshipped mostly by farmers. Thor is a heroic and honest god with unrivaled strength. Some claim he could even swallow a cow whole. With the magical hammer Mjolnir which returns to its owner after being thrown, he smites his enemies with ease."
Thor's affiliation with YHVH and the forces of Law in Shin Megami Tensei is contradictory with his nature as a pagan god and as the idol of those who opposed the advance of Christianity in Northern Europe.
Also contradictory is his loyalty to Chaos in more recent games, as Thor is a deity who opposes chaotic monsters and deities, such as Loki and the frost giants. He is also a protector of the weak, which makes him stand in total opposition to the above mentioned alignment. Furthermore, he is listed as a member of the Kishin race, which are entities of Chaos.
Despite being explicitly described as being red-haired, he is never depicted as such in games of the series.
