#Pashupatastra
The Pashupatastra(sanskrit:पाशुपतास्त्र; the weapon of Pasupati,an epithet of Shiva)in Hindu mythology is an irresistible and most destructive personal weapon of Shiva, Kali and Adi Para Shakti, which can be discharged by the mind, the eyes, words, or a bow.

Never to be used against lesser enemies or by lesser warriors, the Pashupatastra is capable of destroying creation and vanquishing all beings. Pashupatastra is the most destructive, powerful, irresistible weapon mentioned in the Hindu mythology.

In Mahabharata only Arjuna and in Ramayana Lord Rama , sage Viswamithra and Indrajit possessed Pashupatastra.

Translation of Mahabharat regarding the power of Pashupatastra:[3]

O thou of mighty arms, that weapon (Pashupatastra) is superior to the Brahma, the Narayana, the Indra, the Agneya, and the Varuna weapons. Verily, it is capable of neutralizing every other weapon in the universe.

It was with that weapon that the illustrious Mahadeva had in days of yore, burnt and consumed in a moment the triple city of the Asuras. With the greatest ease, Mahadeva, using that single arrow, achieved that feat.

That weapon, shot by Mahadeva's arms, can, without doubt consume in half the time taken up by a twinkling of the eyes the entire universe with all its mobile and immobile creatures.

In the universe there is no being including even Brahma, Vishnu and the deities, that are incapable of being slain by that weapon.
