Red Skull Will Return (From Jotunheim)

It has long been rumoured that the Red Skull will reappear at some point in the Marvel Cinematic Universe. The Nazi villain appeared to perish at the end of 2011’s Captain America: The First Avenger, but some people believe that the Tesseract merely transported him across the universe.
Robert Redford’s Alexander Pierce was rumoured to be a returning Red Skull in disguise in 2014’s Captain America: The Winter Soldier, but since that didn’t turn out to be the case, more rumours have surfaced.
Some people are suggesting that he has been in suspended animation on Jotunheim – home of the Frost Giants – since his disappearance, and will return when Thanos gets his hands on the Tesseract and uses it to bring him back in the Avengers: Infinity War movies.
