===Background===
Indra battled the dragon Vritra, but Indra had sworn an oath to Vritra to not hurt it with weapons made of wood, stone, metal, or any other conceivable weapon, to not hurt it with any object dry or wet, and to neither attack it during the day or night. Indra attacked at twilight, neither day or night, and used a column of sea foam, not wood, stone, metal, dry, or wet, to defeat the dragon. Another name for Indra, Vritrahan, means "the one who kills Vritra."
As the father of Arjuna, Indra favored his victory in what was to be the final fight between his son and Karna, and he understood that Karna could not be persuaded from battling. The armor Karna had been bestowed at birth, Kavacha and Kundala, was such that even a god would find it difficult to destroy, so he formed a plan to take it from Karna. Shortly before the battle, Indra took the form of a due to Karna having sworn an oath to never refuse the request of one. Approaching Karna while he was taking a holy bath, Indra requested "I wish to receive the things you carry." Although he knew of the trap, Karna offered up the requested item, the armor that was his only proof of his lineage.Fate/Grand Order material III - Karna, p.104-113 translated by ComunCoutinho
Karna was not dissuaded from battle despite losing the armor, causing Indra to be touched by his gallant figure. He asked Karna why he proceeded to the battlefield despite that, without even reproaching he who had taken his armor out of his love for Arjuna. Karna replied that Indra was simply a step ahead, and although a god, his love as a father brings Karna joy. He explained his reasoning for proceeding to the battlefield, and Indra saw in Karna the "divinity of Surya himself." Despite being the enemy of his son, Karna's noble behavior charmed Indra to the point he came to adore him. Having taken something from Karna that was greater than his life, Indra decided to give Karna his spear, Vasavi Shakti, as compensation to avoid staining his honor. The greater reason that he was charmed by Karna and came to believe that Karna could wield the greatest spear he had not given even to his own son. After sending off Indra, Karna headed to the battlefield for his battle against Arjuna.
Unbeknownst to most, Raikou was born as Ushi Gozen, a descendant of , and was thus abandoned and imprisoned by her father.Fate/Grand Order - Demonic Fairy Tale: Onigashima - Act 13: And Then, Momotarou… In addition, Ushi-Gozen was the heaven-sent child and the avatar of Gozu Tennou, and Gozu Tennou was the incarnation of (Indra).Fate/Grand Order material IV - Minamoto no Yorimitsu, p.028-039, translated by Clyton at Beast's Lair.

===Personality===
He is crafty, as he disguises himself as a brahmin so that he is able to snatch away Karna's armor so that he will become vulnerable. Despite that, he is honorable as well since he gifted Karna with his own Vasavi Shakti because he is impressed by Karna's nobility. 
==Role==
====Yuga Kshetra: The Black Final God====
Indra, along with the other Hindu Gods (with the exception of Kama and Ganesha), were fused into Arjuna, creating God Arjuna.
==Abilities==
Indra possessed Vasavi Shakti, only permitting himself to use it, which not even him could handle properly. Not even passing it onto Arjuna, he later finds Karna worthy of possessing it.
The Vajra is said to be the symbol of Indra's divinity and was held in one interpretation to be a manifestation of Indra's lightning. In the decisive battle against the Asura Vritra, the thunder god Indra used this weapon to slay him.
