Simon, as a boy, was physically underdeveloped for his age, standing at little more than 4-feet tall. Though valued as one of the most skilled diggers in Giha Village by his Chief, Simon was ignored by the adults and snubbed by the girls, who considered him disgusting because of his peculiar habits and odd smell. Lacking parental figures to help him mature, along with his fear of earthquakes, Simon was plagued by low self-esteem and had many cowardly tendencies. Even after his friendship with Kamina, he continued to act cowardly and doubted his own abilities. However, Kamina's inspirational speeches would give Simon just enough confidence to endure his own fears and to accomplish something.
