What is your favourite hero villain dynamic in books?

Mine is Katniss and Snow. Snow clearly hates how she is trying to bring down his regime and yet respects her.

I like Percy Jackson with

Spoilers for Percy Jackson

Luke and Kronos. Luke was like a big brother to Percy which made his turn to traitor more heartbreaking. Luke was so manipulative. And Kronos wanted Percy to be his vessel over Luke

Least favourite has to be Voldemort and Harry. I personally think they could have benefitted from more interactions. I know that would be hard considering the story but still. They were quite similar

In Twenty Thousand Leagues Under The Sea, I like Arronax’s and Nemo’s dynamic. Nemo is technically keeping him prisoner which makes him a villain and yet Arronax loves seeing everything underwater.
