One of the few still-living MCU villains

Another rumor that’s recently been circulating the web is that Civil War will bring back one of the villains previously left alive (there aren’t too many of them, though). And since Civil War has brought back Thaddeus Ross…

Many fans believe that the general had enough time to perfect and refine the serum used on Emil Blonsky in the Incredible Hulk. By now, he has discovered that he can control the Abomination, switching it on and off, as needed. And, sure enough, the Abomination is the only existing supervillain on Earth who could pose a threat to the Avengers (minus Hulk and Thor).

So maybe it is Emil Blonsky in that stasis tube, with Iron Man defending him. Yes, it is a HYDRA installation – but this can be easily explained if Zemo is manipulating everybody from behind the scenes. If it is indeed so, an Avengers vs. Abomination showdown is more than welcome!
