i was always the loser garou

Yes, Garou died in the manga. It was a significant plot point.

Yes, Garou does die in the manga.

Not really. Garou's appearance in the manga doesn't typically give the impression of being exactly 18.

Some smaller, more niche fanfic communities or forums dedicated to the source material of Suiryu and Garou might also be a good place to find such fanfics. You can ask around in those communities for recommendations or search through their story archives.

For a good character interaction between Garou and Saitama, start with their fundamental differences. Saitama is a hero who is bored with the lack of challenge, while Garou hates heroes. Have them start with a fight, but make it a comical one where Saitama's nonchalance annoys Garou to no end. This can lead to some great dialogue exchanges where Garou tries to taunt Saitama into taking him seriously, but Saitama just doesn't care.

Yes, there might be. The Naruto and One - Punch Man fandoms are both large, and it's not uncommon for fans to create crossover fanfics. In such a fanfic, Naruto could be depicted as a fan of Garou for various reasons, like being impressed by his fighting style.

One idea could be a story where Garou and Metal Bat are forced to team up against a common enemy stronger than they've ever faced. They start off hating each other but gradually learn to respect each other's fighting styles.

I'm not sure if there is a specific 'naruto is like garou fanfiction' out there. Fanfiction can be found on various websites like Archive of Our Own or FanFiction.net, but you'd have to search specifically for it using relevant keywords in their search bars.

Involve conflict. It could be a conflict between different Garou clans, or a conflict between the Garou world and the human world. Your Garou OC could be caught in the middle, forced to make difficult decisions that drive the plot forward. For instance, if humans start hunting Garou, how does your OC respond? Do they try to protect their kind while also preventing all - out war?

You can start by looking on fanfiction websites like Archive of Our Own (AO3). It has a large collection of fanfics from various fandoms, and there are likely to be quite a few 'garou x metal bat' ones there. Just use the search function and type in the relevant tags.
