After a fight with Iron Nail, Steve Rogers can no longer carry the Captain America shield. The effects of the super soldier serum have worn off and now Rogers is an old man. Announced on Marvel's website, CAPTAIN AMERICA #25 starts off this new journey for Steve Rogers and a new person inside the Captain America costume.
This isn't the first time something big has happened in a 25th issue of Cap though. Back in 2007, Steve Rogers was shot and killed at the epilogue of Civil War in issue #25. Now, Steve is just too weak and old to carry on. In an interview with Marvel, writer Rick Remender discusses where this leaves Steve Rogers:
Steve is in a spot where he’s still determined to serve, and he’s still determined to have a positive influence on the world around him. He wants to work to defend his nation and his world, but he’s left in a physical state of not being able to perform. The choices he has before him as to who he’s going to select as his replacement seem very simple at this point—it’s a short list—but we’re revealing a number of characters in #23 who’ve been gone for a while, that decision gets a little trickier. Steve hasn’t had a lot of time to concern himself with these things. Literally a day after the Iron Nail debacle when he lost the Super Soldier Serum and rapidly aged to the physical age he would have been had he never been frozen, he’s forced to make some hard decisions.
Others have taken the mantle before, like Bucky Barnes and John Walker, but it's always Steve who is the true Captain America. Marvel stated they will announce who it is in upcoming weeks, but for now, all fans have is the cover of issue #25. There is speculation to who will take over, but nothing confirmed as of now.
Stay tuned for more info on who will carry the shield.
