5 best anime rivalries of all time, ranked

Sometimes, rivalries are more cerebral in nature, like with L and Light Yagami in Death Note. Light’s moral absolutism is at complete odds with L’s measured definition of justice, and this gap creates a charged dynamic that often feels like a game of mental chess. In other cases, initial hostility gradually morphs into begrudging respect (Izuku Midoriya and Katsuki Bakugo inMy Hero Academia) or even playful bickering despite an unshakeable trust (Sanji and Roronoa Zoro in One Piece).
