I really want to see
Faustus & Batroc in the sequel. Since
Bucky's return as the Winter Soldier is inevitable it should be introduced as a
part of Red Skull's final plan or something like that. Let em
leave Arnim Zola for a threequel.
I think, that
Doc Faustus is an interesting villain, because his psychological mind tricks are really spectacular & that is exactly what we need, when
Steve Rogers is blaming himself for Bucky's death & when he's trying to fit in the world of 21st century. That's exactly, what the sequel needs!
I mean, it worked
in the early issues of Kirby's Cap, so I totally wouldn't mind to see some mind games between Cap & Faustus unleashed on the big screen (especially that particular page, where Faustus made Steve believe, that he's an old man with a bunch of hallucinations: pics included).
Now,
if Faustus is a big psychological threat for Cap, then we need
some physical threats as well. And here's where
Batroc should be introduced. They should change nothing about Batroc's comic history (a very, very skilled mercenary without superhuman abilities from France).
With Bucky they can change some stuff. Like, if in Brubaker's run it's only Karpov, Lukin & USSR secret division, that took part in his mind changing process, then here you can also add Zola's past experiments.
Then again,
I don't want Cap 2 to have too many villains, y'know, but I don't want to see too much resemblance to the first movie in the choice of the villains.
