Captain America working for Hydra?!!!! How long did that last. Plus. It also reminds me of Superman walking across America.
All part of a big comic book storyline caused by Cosmic Cube called Kobik & resolved in Secret Empire comics
They have these storylines thought out well in advance. Big storyline involving many superheroes. villains & teams
