Arjuna:
"Karna then invoked an arrow and shot that, which Arjuna cut off. Whatever weapons Karna shot were cut off by Arjuna. Arjuna then cut off the chariot of Karna. Seeing Karna defeated, the other kings rushed to Karna's rescue but could not stand in front of Arjuna." (Swayamvara)
"Arjuna having the knowledge of divine weapons fired arrows which hit Karna. Karna fainted on the chariot. Karna's charioteer fled with Karna." (Virat war)

"Karna said Let me see your skills. Use all your weapons on me. See if you can do anything. Arjuna said If you had some shame you would not have said this. I killed your brother and you fled. Arjuna and Karna then began fighting showering arrows on each other. Arjuna then killed the charioteer of Karna. All weapons finished, Karna has no option but to leave the battlefield." (Virat War)
"The defeated warriors Drona, Bhishma and Karna also came there. Arjuna then remembered a weapon which could put people to sleep. He used that. All on the field went off to sleep including the animals." (Virat War)
"Karna then faced Arjuna. Karna and Arjuna started fighting, shooting weapons at each other. Karna took got wounded and had to leave. Arjuna then killed multiple soldiers." (Day 14)
"Seeing this, Arjuna renewed his attack. Karna came to assist Ashwatthama and all had to flee, as they could not stand Arjuna's attack." (day 16)
"In the camp Karna was ashamed of having to flee from Arjuna. Duryodhana said If I knew you would not be able to win the battle for me, I would have taken refuge with the Pandavas." (night 16)
"Seeing his son dead and also remembering defeat in the hands of Arjuna, Karna decided to kill Yudhistira." (day 17)
Bhima:
"Picking up the elephants by their trunks, Bhima began hurling them in the air. Karna seeing this rushed there. Seeing Karna, Bhima went and killed the horses of the chariot with his fists. He then kicked the chariot which broke. Karna then fled from there." (day 11)
"Bhima then flung his mace, breaking the chariot. Ashwatthama fled. Bhima tried to chase him. Seeing this, Karna stopped Bhima by showering arrows at him. Bhima using his mace crushed Karna's chariot. Karna got another chariot and fled." (day 12)
"Karna stopped Bhima. Bhima cut off his chariot and his weapons. Karna then fled." (day 14)
"Karna came again, and Bhima began shooting arrows at Karna. Karna fled again." (day 14)
"Bhima then attacked Karna. Karna cut off Bhima's bow. Bhima then hit Karna with his mace. Karna fell on his chariot." (Day 17)
"Duryodhana and Karna were seeing this. Karna tried to control Bhima but could not. Bhima ran around, his face smeared with blood. Thinking this was a rakshasa, anyone who came close to him, ran away." (Duhsasana vadh)
Abhimanyu:
"Seeing this, Karna got angry., He started shooting arrows at Abhimanyu which the young prince easily cut off. Karna could not also stand in front of Abhimanyu for long and had to flee."
"If Karna had to face defeat in his hands, who do you think and defeat him? If you want to defeat Abhimanyu, then you will have fight using unfair means. Do not forget that this is Krishna's nephew. He will be able to defeat all, alone." (Drona mentions it)
Ghatotkatcha:
"Seeing all perplexed, Karna decided to attack. Ghatotkacha smashed Karna's chariot and Karna barely managed to save himself. Ashwatthama then came but could stand the might of Ghatotkacha." (Night 14)
Chitrasen:
"Chitrasen said he was pleased to see the skill of Karna. He then released a few arrows which hit Karna and he fell senseless. While Karna was trying to get up, the army attacked Chitrasen but the gandharva cut off all the weapons of the army. Karna then began showering weapons. Chitrasen then understood that to combat this, magic would be needed. He then made himself invisible and then started showering arrows. Unable to fight an invisible enemy, the army was soon vanquished. Unable to fight, Karna soon gave up."
"In a war with Chitrasen, Karna, Dushasana and Salva had fled the battlefield."
He failed in the Swayamvara:
"Karna then got up. He went and picked up the bow with his left hand. He bent the bow on his knee and tied the bow string. He then shot an arrow which also struck the Sudarshana Chakra and fell down."
"The brahmanas started laughing. The bow that could not be handled by warriors like Jarasandha and Duryodhana, and where people like Drona and Karna had failed, what could a mere brahamana achieve."
Kavacha Kundala could be cut off:
"Saying this, Karna took a sword and then cut off the armor and the earrings from his body."
His character and personality.
Karna traded the armor for a weapon:
"Karna said I know of a weapon that you have that will never miss its mark. Give me that. Indra gave that to Karna, and left with the armor."
Insulted his guru Drona after his death:
"All were in shock on hearing off Drona's death. Karna said to Duryodhana - The Guru had become old and was weak. Leave the Pandavas to me. I will get them for you."
Krishna's last words to karna before karna's death:
"Hearing this Krishna said - At times like this, the evil become preachers. You were an aide of Duryodhana and Shakuni in all evil deeds, Where was your preaching when the kingdom of the Pandavas was taken away? Where was this when the plans to burn the Pandavas alive happened in the house of Lac? Seven of you surrounded Abhimanyu and killed him. Where was justice then?"
Told Dhritarashtra to send Pandava's out of Hastinapura:
"The king called Dushshasan , Karna and Shakuni and asked them what to do. They said send Pandavas away in some ruse."
Karna was namard in Kashidasi aswell.
