Crook 1, or Koggle, was born in a mountainous area and soon moved to a small town. There, he began a love of mischief. While planning a huge destruction of a man's house because the man had taken his favorite stick from him, he caught Croco's attention. Croco told the young villain that he would give him a shot with his new group featuring two other evils, who at the time he called Crooks A and II. Crook 1 was originally Crook 3, as Croco had low expectations for him. The young member of Croco's group quickly went through the ranks of Croco's training and was soon Croco's favorite and most promising pupil.
