History
Captain America's history is presumably similar to his Earth-616 counterpart's up to the point where he was frozen in ice. Because the Avengers were never founded, Rogers' body was never found frozen in ice. He remained there for decades until Blade the Vampire Hunter from Earth-616 managed to find him using coordinates he took from the Pentagon and his enhanced senses.
After being awakened, Rogers briefly met with hero Hyperion while pretending to be a homeless vet. Hyperion's powers strangely malfunctioned while around Rogers. Blade quickly got Rogers away from Hyperion before the situation escalated. Rogers then asked Blade to explain everything that had happened while he was frozen in ice.
Blade and Rogers then began their mission to restore reality to its proper place by gathering members for their Avengers, starting with Echo of Earth-616. Rogers and Blade later recruited Black Panther to their cause while Echo recruited Thor. Brandy Selby of the Star Brand was also recruited after she was found in outer space by the Wakandan Space Command.
