Hindu mythological wars
Hindu mythological wars are the wars described in the Hindu texts of ancient India. These wars depicted both mortals of great prowess as well as deities and supernatural beings, often wielding supernatural weapons of great power. Hindu teachings prescribe war as the final option, to be employed only after all peaceful methods are exhausted. Participation in righteous war, or dharmayuddha, was said to be honourable and was a principal duty of the Kshatriya or the warrior varna, and victory in such wars was regarded as a matter of honour. In Vedic literature

Indra and Vritra
The central battle in the Vedas is between Indra and Vritra, and the defeat of the demon Vritra leads to the liberation of rivers, cattle and Ushas (dawn/light). The Kshatriya class 

War Sacrifices:

Ashvamedha: The famous horse-sacrifice was conducted by allowing a horse to roam freely for a slated period of time, with the king performing the sacrifice laying claim to all the lands it touched. The king whose authority is contested must prove himself in battle or accept the imperial supremacy of the challenging king. When the horse returns safely after the period of time, the main sacrifice is performed, and the king, if successful in obtaining dominance over other kings, is crowned Emperor of the World. The Ashwamedha allows the opportunity to maintain peace if the kings do not choose to contest the sacrificial horse. Rajasuya: Considered the ultimate sacrifice, the king performing the sacrifice must openly challenge every king in the world to accept his supremacy or defeat him in battle. If and when the king returns successfully, having beaten all other known rulers, the performance of the sacrifice will send him to the abode of Indra. Vishvajit Yagna:  a sacrifice performed by Brahmins after a king had won a war. In Puranic Literature

The Devasura War
The perennial battle between the devas and asuras is undertaken over the dominion of the three worlds: Svarga, Bhumi, and Patala, (Heaven, Earth, and the underworld). Both races are technically equal, possessors of great religious and martial powers, but the devas are committed to the worship of the Supreme Being and the practice of virtue. The asuras have atheistic and devious tendencies that grow over time. The divide is the greatest in the Kali Yuga, the final age. Twelve Battles 
In the Varaha kalpa, twelve battles between the devas and the asuras are described in the Brahmanda Purana:

 Narasimha and Hiranyakashipu
 Vamana and Mahabali
 Varaha and Hiranyaksha
 Samudra Manthana: The churning of the ocean
 Tarakamaya War: Soma and Brihaspati
 Adibaka: According to the Devi Bhagavata Purana, the king Harishchandra promised before to Varuna that he would celebrate for his propitiation the great Naramedha sacrifice, when he would offer his own son as a victim to be immolated to cure himself of his disease. When he had second thoughts, the guru Vashishta suggested that he sacrifice a Brahmin boy instead, and the king acquired a boy called Sunasepha for the deed. Vishvamitra urged him to release the innocent child, and when the king refused, taught him a mantram of Varuna, which often invoked, freed him. Vashishta cursed Vishvamitra to be born in his next birth as a baka (crane), and the latter cursed the former to take birth as an adi (myna). The crane Visvamitra built its nest on the top of a tree on the Manasarovara lake and began to live there. Vashistha, too, assumed the form of an adi bird, and built his nest on the top of another tree and lived there. Thus the two rishis spent their days in full enmity towards each other. These two birds used to shriek so terribly loud that they became a nuisance to all, and they fought daily with each other. Brahma then freed them from these curses, and the gurus returned to their ashrams. Traipura: Tripurasura and Shiva
 Andhakara: Andhaka and Shiva
 Dhvaja: In the battle called Dhvaja, the danava Vipracitti, described as the "terror of the celestials", adept in the art of maya and a being who threatened the three worlds, was killed by Indra after penetrating a hundred thousand dhvajas (banners). Varta: The asura Vritra and Indra
 Halahala: According to the Devi Bhagavata Purana, the Halahalas were a sect of asuras who were the first creation of the Trimurtis, when they also possessed the power of creation. The Halahalas, who became very powerful within a short period of time, earned from Brahma all the boons they wanted, and they then conquered the three worlds. At last, they barricaded Kailasa and Vaikuntha as well, so Vishnu and Shiva defeated them after a fierce fight lasting for a thousand years. The deities returned to their abodes and spoke about their achievements. Their wives laughed at the bravado of their husbands. At this Vishnu got angry with Lakshmi and Shiva with Parvati, and in protest the Devis left their husbands. From that day onwards, Vishnu and Shiva began losing their power. Brahma, who divined the reason for the growing weakness of Vishnu and Shiva persuaded Lakshmi and Parvati to return to their rightful places and support their husbands. Yet, Brahma told them that in future he alone would handle the work of creation. Thus were Vishnu and Shiva divested of their right to creation. Kolahala: According to the Padma Purana, Kolahala was a famous asura. In the battle between the devas and the asuras carried on by Subrahmanya, this asura confronted Malyavan and was killed. War Sacrifices Conducted
Ashvamedha: King Sagara performed it for 99 times successfully. If a King performs it 100 times, he becomes eligible to obtain throne of King of Heaven. Sagara also performed this 100th time but it failed because of Indra's evil plot. Vyuha: Cohorts of Battle
Padma Vyuha or the Chakravyuha: A winding, ever-rotating circular formation; considered impenetrable in the Mahabharata by all warriors except for Krishna, Arjuna, Drona, Parashurama, Pradyumna, and Abhimanyu. Abhimanyu had learnt how to break into the formation (in the womb of Subhadra) but not how to break out of it and is trapped inside during the Mahabharata war. Krauncha Vyuha: The crane-shaped formation of an army; forces are distributed to form spanning wing-sides, with a formidable penetrating centre, depicting the crane's head and beak. Sarpa Vyuha: Winding Snake Formation
Makara Vyuha: Crocodile Formation
Sakata Vyuha: Cart Formation
Shukar Vyuha: Pig Formation
Vajra Vyuha: Thunderbolt formation, the toughest and most difficult after Chakravyuha. Kurma Vyuha: Turtle formation
Garuda Vyuha: Eagle formation
Suchi Vyuha: Needle formation
Simha Vyuha: Lion formation

Pralaya: The end of the world
The end of the world is prophesied to happen at the end of the Kali Yuga - the final stage of the world, and the last of the four stages. Kalki, the final Avatar of Vishnu is also prophesied to appear the end of the Kali Yuga, to wage the final battle between good and evil bringing end of the world and start of new world. Shiva Nataraja, the Destroyer, kills the paramount demon of Ego and performs the Tandava Nritya (The Dance of Tandava) on his back, ending with the destruction of the universe performing Rudra Tandava. In Shaktism, the mystical dance by Goddess Kali (the terrifying form of Parvati, Shiva's consort), that is, dark energy for destroying all forms of matter, materials, beings, and illusions, which are absorbed within herself i.e. the Supreme Brahman.

He was also well expert in using celestial astras. He also possessed Mohini astra, Rudra astra etc. Ravana: blessed by his fearsome 10,000 year tapasya to be the most powerful being on earth, invulnerable to every God, demon and living being, save man.

Indrajita: He was the first-born son of mighty Ravana. Originally his name was Meghanada. He was master of illusion war techniques. He became the possessor of several supreme celestial weapons. Through penance, he obtained a boon from Brahma : he could be killed by a common man who could control his sleep for 12 years continuously. He defeated Indra and arrested him. Then Brahma appeared and asked him to free Indra. Meghanada did as Brahma directed and was then granted boon : he would never be killed in any battle, until his Yagna (fire-worship) of his native goddess Nikumbala was disturbed and destroyed. On the completion of the Yagna, a supreme celestial chariot would appear, boarding which, Indrajit would become unkilled in any battle. But Brahma also cautioned him that whosoever would destroy this yagna, would also kill him. He was killed by Lakshmana. Kumbhakarna: the gigantic brother of Ravana was a fearsome monsuter-demon who sleeps for six months at a stretch, rising for only one day and then returning to his slumber. Kumbhakarna could slay hundreds of warriors by the sweep of his hand or step of his foot. He was killed by Rama in the war. Prahasta: the chief commander of Lanka's army who was killed on the 1st day of the war of Rama and Ravana.

Akshayakumara: the youngest son of Ravana who died, fighting Hanuman in Ashok Vatika. Shatrughna: Youngest son of King Dasharatha, youngest brother of Rama. He killed Lavana, son of Madhu and Kumbhini (a sister of Ravana) and became the King of Mathura. Bharata: Younger brother of Rama, elder to Lakshmana and Shatrugna.

Vishnu

Vishnu, the preserver deity, is considered to be the Ultimate Reality in the Vaishnavism tradition of Hinduism. He is the spouse of Lakshmi, the goddess of prosperity. In the Puranas, he periodically takes birth as an avatar upon the earth. Vishnu has 10 avatars: Matsya, Kurma, Varaha, Narasimha, Vamana, Parashurama, Rama, Balarama or Buddha, Krishna, and Kalki. Vishnu is also said to have total of 36 forms other than these ten incarnations, including Mohini, Nara-Narayana, Arjuna, Dattatreya, Dhanvantari, Hayagriva, and several others. In battle, the avatars of Vishnu are aided by a variety of astra, or celestial weapons. The mantra employed to invoke him is Om Namo Narayanaya. His two most popular human avatars, Rama and Krishna, possess many celestial weapons. Krishna also employed a few of these weapons in the Mahabharata. These include:

Kaumodaki: The divine mace; Krishna slays the demon Dantavakra with it. Kodanda: Also called Sharanga, it is a celestial bow wielded by Parashurama, Rama, and Krishna. Nandaka: The sword of Vishnu that is also wielded by his avatar of Krishna. Narayanastra: Narayanastra is one of the most powerful astras in the universe. The personal missile weapon of Vishnu in his Narayana form, this astra lets loose a powerful tirade of millions of deadly missiles simultaneously. The intensity of the shower increases with resistance. The only solution is enacting submission before the missile; only then will it cease. The Narayanastra was first used by Rama in the Ramayana. Then, thousands of years later, this astra was again used by Ashwatthama in the Kurukshetra War against the Pandava army. Apart from Rama, only Ashwatthama possessed this weapon. Parashu: The axe of Parashurama, the sixth avatar of Vishnu. This axe was presented to him by Shiva. Sharkha: The bow of Krishna, 8th avatar of Vishnu. Sudarshana Chakra: The divine, spinning disc with sharp outer spears, one of the four attributes of Vishnu. The Sudarshana Chakra flies at the command of Krishna, spinning away to tear off the heads of his opponents, or to perform any function desired by Vishnu. It is most famously used by Krishna in the Mahabharata. Vaishnavastra: Vaishnavastra is one of the most powerful astras along with the Narayanastra. The personal missile weapon of Krishna, once fired it cannot be thwarted, save by the will of Vishnu himself. Shiva

Shiva, the destroyer deity, is the Ultimate Reality in Shaiva tradition. He is the spouse of Parvati, the goddess of power. He is represented by his forms, Mahakala and Bhairava. Shiva is often pictured holding the damaruka, an hourglass-shaped drum, along with his trishula, a trident-staff. The mantra to invoke him is Om Namah Shivaya. Shiva is also considered as the Mahadeva, the great god. He is often worshipped in his phallic representation, the lingam. Assigned with the task of destroying all of the universe at the end of time, Shiva is one of the most fearsome warriors as well as the revered yogis in Hindu tradition. Tandava is the dance of this destroyer deity, which he performs over the body of a demon. Shiva employs his power to kill the Asura Tripura, destroying the flying three cities of Tripura. In battle, Shiva and his amshas (spirits) deploy formidable weapons controlled by him. Some of these are:

Arrow of Shiva: It can destroy creation. Returns to the quiver after being used. Chandrahas: Sword of Ravana granted by Shiva as a boon. Ekasha Gada: The mace of Shiva. A blow from the weapon is the equivalent of being hit by a million elephants. Girish: A special sword of Shiva with unique characteristics. Jayantha Vel: A spear which contains the power of the third eye of Shiva. Khaṭvāṅga: In Hinduism, the god Shiva - Rudra carried the khatvāṅga as a staff weapon and are thus referred to as khatvāṅgīs. Maheshwara Chakra: The chakra of Shiva. Parashu: The axe of Shiva given to Parashurama (the sixth avatar of Vishnu). Pashupatastra: An irresistible and the most destructive personal weapon of Shiva, discharged by the mind, the eyes, words, or a bow. This is the most devastating weapon in the universe. Sage-King Vishwamitra, and Arjuna are only other persons who possessed this weapon. Pinaka: The celestial bow of Shiva. (Shiva's bow): A bow given by Shiva to Janaka and was broken by Rama during Sita's swayamvara
 Vijaya Dhanush:Vijaya (bow): A bow given by Shiva to Parasurama to kill Kshatriyas
Shiva Kaakam: An unconquerable weapon of Shiva. Shiva Parham: A long noose (of Shiva) from which even the gods can't escape from. Shiva Vajra: A vajra that is as powerful as Indra's Vajra. Teen Baan: Shiva gave Barbarika three infallible arrows (Teen Baan). A single arrow was enough to destroy all opponents in any war, and it would then return to Barbarika's quiver. Trishula (Trident): The trident of Shiva. Shakti

Shakti is the supreme goddess in Shaktism, the goddess-centric sect of Hinduism. Both a supreme being and an energy that is considered to be the source of all works of creation, preservation and destruction, Adi Parashakti is held by Shaktas to be the source of the Trimurti, the universe and all of creation. She is regarded to have assumed many incarnations to fight with demons, including Parvati, wife of Shiva, Lakshmi, wife of Vishnu, the complete avatar of Shakti herself, according to the Devi Gita and Durga Saptashati, the main scriptures for Shakti worshipers. As the goddess Parvati, she is considered to be the most powerful of all deities. Sometimes, the gods worship Parvati, who came before them in different avatars:
 Durga, who killed the demon Mahishasura
 Kali, the most ferocious form of the Goddess, who can not be pacified by anyone after war. Chandi, the gentle manifestation of Durga or Kali, who killed Mahishasura in the battle of Alkapuri. Kanyakumari, who killed Banasura
 Chamunda, who killed Chanda and Munda
 Kaushiki, who killed Shumbha and Nishumbha
 Minakshi, who defeated all the demigods and destroyed the arrogance of all demigods. Shakti is usually depicted as having the weapons of all the gods, including those of the Trimurti. She holds the trishula of Shiva, the chakra of Vishnu, the Vajra of Indra, and the gada of Yama. Celestial Weapons
An astra is a powerful celestial weapon or missile that is to be hurled at an enemy. Generally astra is in form of an arrow. Astras can be invoked using incantations (mantras). Different astras have different power. A Shastra is a personal weapon like swords, bows, spades, axes, spears and maces which must be constantly operated by a warrior. Brahmastra: Embedded with the mystical force of Brahma, this weapon releases millions of missiles, great fires and a destructive potential capable of extinguishing all creation, if not used by and aimed only at a celestial fighter. It was used multiple times in the Ramayana, Indrajit used it against Hanuman, Lakshmana asked permission to use it against Indrajit, which Rama declined, Lakshmana used it to kill Atikaya,  Rama used it as final arrow to kill Ravana. In the epic the Mahabharata, it is said that the weapon manifest with the single head of Brahma as its tip. In the Mahabharata era Parashurama, Bhishma, Drona, Karna, Kripa, Ashwatthama, Arjuna, Yudhishtira, Satyaki  and many Maharathis possessed the knowledge to invoke this missile. Brahmashirsha astra: A weapon capable of greater destruction than the Brahmastra. It can burn all creation to ashes once discharged, Arjuna and Ashwathama both used it against each other after the Mahabharata war. Capable of killing even heavens. Was used by Ashwatthama on Parikshit. It is thought that the Brahmashirsha is the evolution of the Brahmastra, 4 times stronger than Brahmastra. "It blazes up with terrible flames within a huge sphere of fire. Numerous peals of thunder were heard, thousands of meteors fell and all living creatures became terrified with great dread. The entire sky seemed to be filled with noise and assumed a terrible aspect with flames of fire. The whole earth with her mountains and waters and trees trembled." When it strikes an area it will cause complete destruction and nothing will ever grow, not even a blade of grass for the next 12 years. It will not rain for 12 years in that area and everything including metal and earth becomes poisoned. In the epic Mahabharata, it is said that the weapon manifest with the four heads of Brahma as its tip. In the Mahabharata, Agnivesha, Karna, Drona, Ashwatthama and Arjuna possessed the knowledge to invoke this weapon. Brahmanda astra: This is the most powerful weapon of Brahma. It was first used by sage Vashishtha against Vishwamitra's (who was King Vishwarath at that time) Brahmashirsha, as only Brahmanda astra can stop Brahmashirsha astra, it was also used by sage Piplad against Shani to avenge his father's death.In the epic Mahabharata, it is said that the weapon manifest with the all five heads of Brahma as its tip.Brahma earlier lost his fifth head when he fought with Siva.This weapon is said to possess the power to destroy entire solar system or brahmand, the 14 realms according to Hindu cosmology. In some texts it is called Brahma-dhanda astra, the weapon created by Saptarishi's to counter any weapon ever created, even that of Trimurti's. The rishi of this weapon is Para Brahman. It is stated to be the most difficult astra to obtain. Capable of destroying entire universe in a blink of an eye. Vishvamitra used all kinds of divine weapons against sage Vashistha, even Pashupatastra, but the Brahma-dhanda astra of Vashistha neutralized and swallowed all astra (weapon) of Vishwamitra proving that Brahma-dhanda astra is the most powerful of all astras. Karna, Bhisma and Drona were the only warriors in the Mahabharata who possessed the knowledge of this weapon.
