Is this steve Rogers (I thought he was dead?!?) or bucky?I had to go and do some digging because I hadn't bought a Cappy book in decades. But as I can find on the Internet tubuals... the original WWII Captain America, Steve Rogers, was thought to be dead but was in a "time rift" of some sort. Bucky took over for Steve and is now the official Cappy. Rogers is back out of the time rift but is listed as retired.
Depends on which “volume” and publishing of captian america. Thats true in some publishings, in others he died when he was assassinated exiting the courthouse at the very end of marvel civil war. Punisher took over for a bit as captian america but then handed off the shield and cape to bucky/winter soldier after he decided that his ways would not have made cap proud.
