Fan Casting Isaiah Bradley in The Falcon and the Winter Soldier (The Bucky Cap Version)

As opposed to his mainline MCU counterpart, this Isaiah Bradley was already well known to the general public thanks to a sympathetic scientist leaking government information in the early 1960s leading to a campaign that successfully freed him. Nowadays, he's basically the show's equivalent of Terrence Mann, a once well-known figure who is now a recluse. He's also the one who tells Bucky that the journey to becoming Captain America is no easy task and brings up all the holders of the mantle who ended up dead.
