From a young age, Tobirama was distinguished by a stern disposition and bluntness, uninclined to sentimentality. He early realized the futility of endless clan carnage and sought a pragmatic exit from the bloody deadlock. He placed rules and order above emotions, believing that only a strict system could curb the chaos of war. Even then he acted as a counterweight to the idealism of his elder brother Hashirama, checking him when the latter became too enamored with dreams. Despite his outward coldness, the death of his younger brothers deeply wounded him and strengthened his resolve to change the shinobi world. Toward the Uchiha clan he felt wary, bordering on antipathy, considering them obsessed with their own superiority and vengeance. In battle he was calculating and ruthless, giving the opponent not the slightest leeway. His actions were marked by swiftness and precision, and his attacks fell upon the enemy at the most unexpected moment. He knew no hesitation if it came to protecting his family or the future of their clan. The mortal wound inflicted on Izuna Uchiha was for him not an act of personal vengeance, but a military necessity dictated by the logic of survival. When Madara suffered defeat, Tobirama was ready to finish him off to once and for all eliminate the threat, and only Hashirama's intervention stayed his blade. He sincerely loved and respected his brother, but considered his soft-heartedness a dangerous weakness. Even in those years the future ruler was already discernible in him, for whom the stability and security of the whole were more important than the fate of an individual. His will was as unbending as the sword in his hands. And although he rarely showed emotion, his anger, when it did break through, was terrifying and unstoppable.
