Superman: Birthright
Superman: Birthright was a very well-regarded limited series comic written by Mark Waid, illustrated by Leinil Francis Yu and Gerry Alanguilan, and coloured by Dave McCiag. It was originally published by DC as twelve comic book issues from 2003 to 2004, then collected as a trade paperback.
It's a Superman origin story, about a supernatural alien refugee who was adopted as a baby.
He can't help himself from helping people to the best of his abilities, which are unique in his new home. This inevitably puts an expiration date on his ability to fit in with those around him, who then become afraid of him, forcing him to move on.
He learns to reconcile these conflicting needs, to both befriend and help people, breaking the pattern of endless travelling by leading a double life. In one life, he openly lives as himself in order to help people, embracing his inherited abilities, along with his ancestors' culture as much as he can piece it together. In the other life, he puts on an act, hiding who he really is in order to settle down and make longer lasting friends, or at least co-workers.
In spite of this, he still remains an outsider, his meek persona excluded from after-hours socialising. And yet he still chooses to help the very people who shun his fake persona and, worse, outright fear and distrust his real one. He helps them not because he expects their affection in return, but because it's the right thing to do.
Superman: Birthright explores what it's like to have to hide your true self, and deal with the conflict that brings. It's surely relatable to closeted LGBT people and masking autists. It equally explores what it's like to be culturally the same as your peers yet visibly different, presumably relatable to those who were transracially adopted, as well as immigrants who found their new home when they were as young as the protagonist was.
It's a very US story. First published during the post-9/11 mass hysteria, it's a plea not to be afraid of immigrants, nor to give up freedom for the illusion of safety. Reading it in 2026, in the "post-truth" Trump era, it's unfortunately just as relevant today.
I know pretty much nothing of Superman outside of osmosis and now this one book, so I can vouch for it being a good standalone story in its own right, with no noticeably gratuitous cameos or references. You don't need to know any lore going in.
Superman is mostly pitted against a single antagonist, his childhood friend who, in his own way, is just as powerful and just as lonely. The key difference seems to be that his friend was seemingly mistreated, and so learns to mistreat others, while Superman grew up in a loving family, and passes on that love.
While it's still a superhero story, and it does end in the kind of epic battle that makes me tune out, it's just as much a character-driven story as a plot-driven one. It's an excellent introduction to Superman, and although I admittedly lack a frame of reference, if you only read one story about him, I gather this is probably the one to go for.
