Captain America Snow Queen AU where Steve goes on a journey to find his childhood friend with the help from various magical friends, like the falcon boy, Sam, and the robber girl, Natasha. Shards of ice have turned Bucky cruel and forgetting and have trapped him in eternal winter, trying to solve impossible puzzles from pieces of shattered ice.
now i haven’t seen winter soldier yet, but i was pretty sure this was the actual plot
Seriously though the original story is perfect. Let me just change names/pronouns:
“But can you not give little Steve something to help him to conquer this power?”
“I can give him no greater power than he has already,” said the woman; “don’t you see how strong that is? How men and animals are obliged to serve him, and how well he has got through the world, barefooted as he is. He cannot receive any power from me greater than he now has, which consists in his own purity and innocence of heart. If he cannot himself obtain access to the Snow Queen, and remove the glass fragments from little Bucky, we can do nothing to help him.”
