Forgive me if this has been done before (as this is kind of an obvious one). But I couldn't resist this suggestion.
Inigo Montoya, one of the most skilled swordsmen of his era, and known for his quest for revenge against the six-fingered man who killed his father, engages in a sword fight with another revenge-seeking swordsman. Namely Oberyn Martell, the Red Viper.
When the two clash swords, who will emerge triumphant?
