In addition to Daredevil and Jessica Jones, we will soon be introduced to Luke Cage and Iron Fist before they all team up to save the day in the Defenders miniseries.
While Jessica Jones and Luke Cage are brawlers who simply use their super strength to overpower their foes, Iron Fist and Daredevil use their martial arts training to engage in fast and furious battles.
Daredevil and Iron Fist will presumably have a fair amount in common when they meet in The Defenders.
We have a while though, as Luke Cage and Iron Fist are coming first.
