Madara's childhood was a product of the times he lived in: the constant fighting made him a perfectionist that would keep at something until he mastered it, and his triumphs on the battlefield made him very confident in his abilities and talent. Whenever one of these personality traits was challenged, as they tended to be by Hashirama, Madara's competitive streak would emerge. Madara did not mind Hashirama's influence in this regard. His best friend is Hashirama. Madara has one brother, Izuna.
