The only Kaurava who survived in the kurukshethra war

Yuyutsu : Yuyutsu in the Hindu epic Mahabharata was a son of  Dhritharashtra with sugandha ( Gandhari's maid).

•  Fearing problems with Gandhari's pregnancy which had continued for almost two years, Dhritrashtra had a child from Sughada, a woman from Vaishya Varna, who is lady in waiting to Gandhari. 

• He was born on the same day as Duryodhana and was elder to Dushasana

• He is celebrated as a moral warrior who chose the path of righteousness and He forwent his family bonds in order to side with dharma.

During Kurukshetra War

• Since Mahabharata was called the righteous war, both sides (Pandavas and Kauravas) were given absolute freedom to choose any side they wished.

• Before the onset of the battle of Kurukshetra War between Kauravas and Pandavas, Yuyutsu shifts from Kauravas to the Pandava camp. Yuyutsu fought the battle on the side of the Pandavas. 

• He was one among the 11 Maharathis (capable of fighting 720,000 warriors simultaneously) among the Kauravas. Yuyutsu was one among the eleven warriors to have survived the war.

• After the war When the Pandavas decided to retire from the world at the start of the Kali Yuga and departure of Krishna, Yudhishthira gave the charge of supervising the kingdom to Yuyutsu while Parikshit (Abhimanyu's son) was made the king 

Theen Baan Dhaari (Grand Son of Bheema) : Who gives his Head as charity to lord krishna

Barbarika  was the son of Ghatotkacha and  grandson of Bheema. He is believed to have been sacrificed before the Mahabharata war to ensure the victory of his grandfathers, the Pandavas.

• Even in his childhood, Barbarika was a very brave warrior. He learnt the art of warfare from his mother. The lord Shiva gave him the three infallible arrows. Hence, Barbarika came to be known as "Bearer of Three Arrows"

• When lord kishna asked how many days he would take to finish the mahabharatha war alone, Barbarika answered that he could finish it in one minute.

• Krishna then asked Barbarika how he'd finish the great battle with just three arrows. Barbarika replied that a single arrow was enough to destroy all his opponents in the war, and it would then return to his quiver.

• He stated that, the first arrow is used to mark all the things that he wants to destroy. If he uses the second arrow, then the second arrow will mark all the things that he wants to save. On using the third arrow, it will destroy all the things that are not marked and then return to his quiver. In other words, with one arrow he can fix all his targets and with the other he can destroy them.

Test of Krishna

• Krishna challenged him to tie all the leaves of the Peepal tree under which he was tanding, using his arrows. Barbarika Baliyadev accepts the challenge and starts meditating to release his arrow by closing his eyes. As Barbarika starts meditating, Krishna quietly plucks a leaf from the tree and hides it under his foot. When Barbarika releases his first arrow, it marks all the leaves of the tree and finally started hovering around the leg of Krishna. Krishna asks Barbarika why the arrow was hovering over his foot. Barbarika replies that there must be a leaf under his foot and the arrow was targeting his foot to mark the leaf that is hidden underneath. Barbarika advises Krishna to lift his leg, otherwise the arrow would mark the leaf by piercing Krishna's foot. Krishna then lifts his foot and the first arrow also marks the hidden leaf. The third arrow then collects all the leaves (including the hidden leaf ) and ties them together. By this Krishna concludes that the arrows are so powerful and infallible, that even if Barbarika is unaware of the whereabouts of his targets, his arrows can still navigate and trace his intended target

    

 Krishna asks Barbarika's head as charity ?

• Krishna gets a deeper insight about Barbarika's phenomenal power and in the form of Brahmin  sought charity from Babarika.  Barbarika promised him anything he wished.

• Krishna asked him to give his head in charity  (because barbarika promised his mother that, if he felt the urge to participate in the battle, he would join the side which would be losing). 

•  Krishna then explained to him that before a battle, the head of the bravest Kshatriya needs to be sacrificed, in order to worship/sanctify the battlefield. Krishna said that he considered Barbarika to be the bravest among Kshatriyas, and was hence asking for his head in charity.

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.

Astra's (Weapons) used in Hindu epics

Brahmaastra : Brahma, the Creator

Would destroy entire hosts at once. Could also counter most other astras.  In the epic Mahabharata, it is said that the weapon manifest with the single head of Lord Brahma as its tip.   Parasurama, Bhishma, Drona, Karna, Kripa, Ashwatthama, Arjuna, Yudhishtir and several Maharathis possessed the knowledge to invoke this weapon.  It is the only weapon capable of piercing the Brahma Kavach (invincible armour of Lord   Brahma). Atikaya,  one of Ravan's sons possessed the invincible armour of Lord Brahma that could only be pierced by a Brahmastra and was killed by Lakshmana (brother of Lord Rama) using a Brahmastra.  In ancient Sanskrit writings, the Brahmastra was a weapon created by Brahma,along with its more powerful versions like Brahmashirsha astra and Brahmanda astra.

Brahmashirsha astra: Brahma, the Creator

Capable of killing devas.  Was used by Ashwatthama on Parikshit.  It is thought that the Brahmashirsha astra is the evolution of the Brahmastra, 4 times stronger than Brahmastra.  In the epic Mahabharata, it is said that the weapon manifest with the four heads of Lord Brahmaas its tip.  In the Ramayana, Indrajit invoked the Brahmashira astra and charged its power onto his chariot, bow and arrows.  Aided by its exceedingly destructive power, Indrajit was able to slay 670 million vanaras in one day and managed to defeat Rama and Lakshmana.  In Mahabharata era Parasurama, Bhishma, Drona, Karna, Ashwatthama and Arjuna possessed the knowledge to invoke this weapon.

Brahmanda astra: Brahma, the Creator

A defensive weapon. Capable of repelling the Brahmastra.  Used by Vashishta against Vishwamitra.   In the epic Mahabharata, it is said that the weapon manifest with the all 5 heads of Lord Brahma as its tip.  Brahma earlier lost his fifth head in a fight when he fought with Lord Siva.  This weapon is said to possess the power to destroy the entire solar systems or Brahmand, the 14 realms according to Hindu cosmology.  In Mahabharata era Parasurama, Bhishma, Drona and Karna possessed the knowledge to invoke this weapon. 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 said to be the most difficult astra to obtain. Capable of destroying entire multiverse 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 of Vishwamitra proving that Brahma-dhanda astra is the most powerful of all astra's.

Gandiva (bow) : This bow was created by Brahma, the Creator of universe. 

Brahma held it first for a thousand years, then Prajapati held it for five hundred and three years, Indra, for five hundred and eighty years, and Soma for five hundred years.  After that Varuna held it for a hundred years before handing it to Arjuna along with a Kapi/Hanuman bannered chariot, and two inexhaustible quivers, as requested by Agni during the Khandava-daha Parva.  The bow was decorated with hundreds of gold bosses, and had radiant ends.  The bow was worshiped by Devas, Gandharvas and Danavas.  No ordinary person could wield the Gandiva bow.  When fired, the bow made the sound of thunder.  It has special qualities like being indestructible, having 100 bow strings, etc.  which always gave the wielder a heavy advantage over his opponent.  Arjuna always used this bow since he acquired it, which gave him a heavy advantage over his opponents. After the death of Krishna Arjuna found it difficult to wield the Gandiva bow.
