Merlin
In Marvel Comics, Merlin AKA Merlyn is every bit as powerful as the classic depictions of the character and it would be really great to see a live action depiction of their interpretation of him.
The “Merlin†name is more of a title in Marvel and a gestalt/composite of the various characters that have used the name, but a less complicated version could be used on screen.
He hasn’t really appeared very much in the comic books but, when he has appeared, he has proven himself to be extremely powerful.
It would be cool to see him appear – either in a television show on screen – to warn some heroes (perhaps Doctor Strange or S.H.I.E.L.D.) about an impending mystical or supernatural threat. He could even have travelled through time to issue said warning, because that would be awesome (can you imagine him interacting with someone like Nick Fury?!).
