So, title pretty much says what this is about. My knowledge about Marvelverse comes from movies mostly. I have been thinking about pitting C'tan against some people, but i don't want to make it a stomp unintentionally, so i am asking you Marvel experts for advice for who would be a good match for one.
Scenario for battle would be following:
C'tan is at War in Heaven power level
Battle starts at Earth, but can extend anywhere
Opponents starts from Northpole and other from Southpole, but they are able to sense others presence
Victory by death
