As a cub, Simba was quite adventurous, inquisitive, and impressionable. He highly admired his father, Mufasa, and wished to someday become a ruler as mighty as he, spending much of his time either learning the ways of a king or simply envisioning what life would be like with such power and self-esteem. This inflated his ego, making him brash and cocky, and additionally led to troublesome situations, as his viewpoint on Mufasa led him to believe being a king meant being fearless and looking for unnecessary danger, just to prove how mighty one could be.
