In his early years, Indra was a caring, loving, and very mature for his age child who sincerely looked after his younger brother Ashura and worried about the purity of Ninshu's teachings. From childhood, he was distinguished by modesty and did not flaunt his genius, sincerely wanting to help people. However, after the awakening of the Sharingan and secret conversations with Black Zetsu, his personality began to change. He became increasingly proud of his exceptionality and began to demand absolute perfection from himself and those around him. He came to believe that one could only rely on one's own strength, and preferred to act alone. His faith in the law became so strict that he allowed no exceptions and severely punished transgressions. At the same time, he did not yet feel hatred toward his father or brother, but jealousy and a sense of injustice gradually corroded his heart. He was convinced that order and peace could only be achieved through power and coercion. Toward the followers of Ninshu who began to use chakra only for physical development, he felt growing disappointment. His once warm disposition gave way to cold calculation and arrogance. He became withdrawn and distanced himself even from those who loved him. During this period, he had not yet crossed the line, but his ideology had already begun to diverge from his father's. His genius mind created hand seals, which became a revolution in the use of chakra. He sincerely believed that his path was the only correct one. Despite his pride, he still felt deep respect for his father, although he believed that Hagoromo underestimated him. His personality in this period represents a tragic transition from a kind genius to a future tyrant.
