Val Armorr was the son of one of Japan's greatest crime lords, Kirau Nezumi, also known as Black Dragon. When he was born, his mother, the American secret agent Valentina Armorr, tried to hide him from his father, but she failed and was killed for her affront. Japan's greatest hero Sensei Toshiaki (the White Crane) eventually killed Black Dragon for his crimes and adopted the infant Val. Val became the youngest warrior ever to earn the title Samurai, and he went to work for his local shogun. However, after trying his best and failing to please his supervisor, he quit and searched the galaxy for new forms of battle to master. When Val returned to Earth, he found that the Legion of Super-Heroes was searching for new recruits to battle the Khunds. He applied, and, although he had no superhuman powers, was accepted when he challenged Superboy to single combat and so impressed the Boy of Steel that Superboy vouched for his admission to the Legion (Adventure Comics #346 clearly shows that though Superboy was surprised by the Kid's skill, strength, and speed, Val clearly had bitten off more than he could chew and could do Superboy no harm). His Legion career almost ended ignominiously when fellow recruit Nemesis Kid framed him for betraying Earth to the Khunds, but Nemesis Kid's own treachery was discovered in time, and Val went on to become one of the greatest Legionnaires ever. As Karate Kid, Val was the Legion's leader for one term and once took on the entire Fatal Five single-handedly, clearly defeating the Persuader, Emerald Empress, and Mano. Val fell in love with Princess Projectra, who joined the Legion at the same time he did. In order to prove his worthiness of the princess' hand, he took a leave of absence and spent about a year in the primitive 20th century.
