Marvel's latest Captain America to join the Multiverse is one of the saddest variants of the character ever depicted, because he has absolutely no one in his life. Steve Rogers is not one man, but one of many men throughout the Multiverse - and some are less fortunate than others. One in particular may have the heart of a Captain America, but he certainly does not have the luck.
Avengers Forever #14, written by Jason Aaron, Jim Towe, Frank Martin, Chris Sotomayor & Morry Hollowell, continues Jason Aaron's five-year story of the Avengers in the heart of the Multiverse. Multiple Avengers from different universes assemble to take on Mephisto and his Council of Red: a nigh-infinite army of demons who desire the power of the God Quarry, the space between universes. A lone Steve Rogers, armed with only a variant of Thor's hammer, fends off a horde of enemies, but he is quickly cut down.
The Loneliest Captain America Dies Without A Single Friend
To make matters worse, as a dying Steve lies in another Steve's arms, he begs the latter to deliver a letter he wrote before the battle. The letter is only addressed to "to Whom it May Concern" - because this Steve Rogers had presumably never met any of his allies in his universe. He never got the chance to know Bucky Barnes, Peggy Carter, his fellow Avengers or anyone else in the modern era. Steve Rogers is almost always a man out of time, but this variant is utterly, completely alone.
Captain America suffers whenever one of his friends is wounded or lost in battle, and it hurts him more than others. While little is known of Steve Rogers' early life, readers are aware that he grew up relatively poor, born to Irish immigrants and didn't have many friends of family in the city. This led him to cherish every person, both civilian and military, and he is far less well-adjusted to loss than other superheroes. While this is true of the 616 Captain America, the others will almost certainly follow suit (given that they are nearly identical in both background and moral centers; every Captain America in this story has so far been able to lift Mjolnir).
This Steve is sadly unmourned by his comrades; there is simply no time when all of existence is threatened. But after Mephisto and Doctor Doom are dealt with, the Avengers would do well to remembers the fallen. Not everyone has led Captain America's life, but all Steve Rogers are worthy in their own way.
