Hmm, if it was the traditional Defenders I'd agree. As he's one of the few beings who could prove a challenge to a group including Dr Strange, Hulk, Namor, Silver Surfer etc. But the Street level Netflix version, would be somewhat out of their league. I'd rather Mephisto was kept for maybe a Dr Strange or Avengers movie. (It's too late I suppose for the character to pop up in Infinity War. But that would have been a nice tip of the hat to the original Infinity Gauntlet Storyline. I suspect Loki will play the equivalent wild card in the movies.)
