I'm not sure who 'Helmut Novel' specifically is. It could be an ordinary person with this name, or perhaps someone known in a specific community, field, or region that I'm not familiar with.
Since I don't know who Helmut Novel is precisely, I can't tell you the specific works related to him. It could be anything from books if he is a writer, to art pieces if he is an artist.
In some of the stories, Baron Zemo's redemption arcs are fascinating. He was a character who had done a great deal of wrong, but there were moments where he was faced with choices that could lead him towards a more positive path. His internal struggle between his villainous nature and the possibility of change made for very thought - provoking stories. For example, when he was forced to team up with heroes in a situation where their common enemy was even more dangerous. This put him in a position where he had to reevaluate his values and actions.
Since I don't know the details of 'helmut the forsaken child novel', it could be that Helmut, the forsaken child, embarks on a journey of self - discovery. He may encounter various characters along the way, some who help him and some who oppose him. The story might also explore themes like loneliness, survival, and the search for family or acceptance.
One common theme is redemption. Many fanfictions try to show Zemo in a new light, perhaps on a path to redeem himself with the help of the oc. For example, the oc might be the catalyst for Zemo to question his actions and strive for a better self.
I don't know the exact main characters as I haven't read it. But surely Helmut is one of the main characters since the title has his name. There might be other characters like the people who forsook him or those who might help him later on.
