Regardless of whether or not you’re a comic fan, chances are that you may not have heard of Nuke. Frank Simpson was a test subject of the Weapon Plus programme (an offshoot of the super soldier programme which created Captain America), but that process didn’t quite work out all that well, leaving him superpowered and deranged.
He’s also a Vietnam War veteran, making him almost a twisted parallel of Steve Rogers. Nuke is more powerful than Cap, and it would make sense for him to be introduced in a future Captain America movie. The WWII super soldier’s perspective on the war he missed has always been a fascinating area to explore in the comic books, and would be here too. The thought of Johnson facing off against Chris Evans is this role is also immensely appealing and he certainly has the right look and stature to convincingly bring him to life.
