Do any mcu movies show a hero defeating thanos?

Available production information for the Marvel Cinematic Universe confirms that Thanos is a central antagonist across multiple titles. The only documented instance in which Thanos is defeated occurs in Avengers: Endgame, where the collective action of the Avengers and their allies results in his defeat. The evidence does not list any instance in which a single hero, acting alone, defeats Thanos. Consequently, no MCU movie currently illustrates a solo hero vanquishing the Titan.
