who is the Kaurava Warrior who is although supirior to Arjuna is slayed by him in the War?

Karna was arguably the most powerful warrior among the Kauravas, superior even to Arjuna in martial skill. He had divine weapons, impenetrable armor, and was equal to Arjuna in archery. However, due to curses, his chariot getting stuck in mud, and his promise not to attack Arjuna twice, Karna was killed by Arjuna on the 17th day of the war.
