Marvel Comics recently instituted a big change to their iconic character Captain America in their first issue of Steve Rogers: Captain America #1. The character, spoilers ahead if you haven't read the first issue, is revealed to be part of Hydra in the final panel of the book, which most likely has something to do with the Red Skull. During his time as Onslaught, the villain teased he had set something in motion, and this is most likely the result of that tinkering.
