The most skilled warrior ever

Indrajit or Meghanada was a prince of Lanka and a conqueror of Indra Loka (heaven). He was mentioned in the Indian epic Ramayana as the son of king Ravana.

•  Ravana wanted his son to be a great devotee of Lord Shiva and equal to Lord Shiva in warfare. As per the wish of Ravana, Indrajit was blessed to be a warrior equal to Lord Shiva.
• He was a mighty Atimaharathi. He is considered as the most powerful and the only warrior to ever possess the three ultimate weapons of Trimurti, i.e. Brahmanda astra, Vaishnava astra, and Pashupatastra.
• He acquired all kinds of celestial weapons from his Guru Shukra, lord Brahma, Vishnu and Shiva. By defeating the devas in the heaven he took their weapons and become the possessor of all kinds of divine weapons of deva, asura's and Trimurti's.
• He even twice defeated Ramaand Lakshman, the avatars of Lord Vishnu. Indrajit killed 670 million Vanara's in a single day, nearly exterminating the entire half man-half monkey race.

Indrajit is said to be the one of the most skilled warrior ever surpassing even Rama, the avatar of Vishnu.

•  Indrajit with the help of Shukracharya acquired weapons from Lord Brahma, Vishnu and Shiva, including the boon that he would remain immortal as long as he fought from the divine chariot which rose each time he performed sacrifices to Brahma at Nikumbhila.
• He was said to be so skilled in archery that he could slay multiple opponents with one arrow shot from his bow. Indrajit was also capable of spreading darkness and ignorance among enemies, which greatly empowered the might of the Rakshasas.
• He even defeated Indra and all Devas and captured all of them. Indrajit was well versed in using divine weapons and shot serpents in the form of arrows at Rama and Lakshmana. On the second battle at Lanka, Indrajit infused the power of the Brahmashira astra into his chariot, bow and arrows and slew six hundred and seventy million Vanaras in one day, even defeating Rama and Lakshmana. However, they were all resurrected when Hanuman brought mystical herbs of healing powers. Indrajit was capable of producing a false version of Sita and killing her in front of Vanaras, demoralizing them.

Lakshmana had to employ deceit to kill Indrajit. 

• Lakshman started the fight with Indrajit before sunrise, which was considered to be prohibited at that era. Lakshmana with the help of Vibhishana, the brother of Ravana by employing deceit disrupted the sacrifice of Indrajit at early morning.
• Lakshmana with the help of Vibhishana, who had earlier betrayed his brother Ravana and his country, fought with Indrajit in an unfair war and finally killed him.
