Arjuna
Death of Jayadratha: Arjuna came to know that Jayadratha blocked the other four Pandavas, at entrance of Chakravyuha, due to which Abhimanyu entered alone and was killed unfairly by multiple Kaurava warriors on the 13th day of the war. Arjuna vowed to kill him the very next day before sunset, failing which he would kill himself by jumping in a fire. The Kauravas hid Jayadratha from Arjuna in a formation, knowing that Arjuna's death would result in a Kaurava victory. Arjuna defeated all protectors of Jaydratha including Karna, Drona, Kripa and Ashwatthama and killed Jayadratha. Jayadratha had a boon from his father that whoever would be responsible for his head falling to the ground would have his own head blown up. So, Arjuna beheaded Jayadratha with an arrow that carried his head to the lap of his father, who was awoken from his meditation and ended up dropping the head to the ground, thus resulting in the explosion of his own head.
