In reference to this post (bc I can’t stop thinking about it), you know who else Madara canonically experimented on? Nagato. He transplanted his Rinnegan eyes into a little kid who was so young every just thought they developed naturally. Nagato must have been tiny. And Madara just…selects this Uzumaki couple, stalks them, then finds a moment when they’ve left their child alone and surgically removes his eyes????
God, Madara. You win the Creep of the Century award, to go with your Psychotic Bastard trophy. Fucking congrats.
