Sasuke and Madara Uchiha are the two strongest members of the Uchiha clan in history, tracing their lineage back to Indra Otsutsuki, the son of the Sage of Six Paths. Both individuals played huge roles in Masashi Kishimoto's Naruto, with the former serving as the rival of the series' protagonist, and the latter being one of the main antagonists of the Fourth Shinobi World War.
