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.
Metal Bat in One - Punch Man (OPM) fanfiction often has his character explored in various ways. Some fanfictions might focus on his backstory, like his relationship with his sister. In fan - made stories, he could be depicted in new battles, showing off his strength and his unwavering determination even more intensely than in the original manga or anime.
One possible fanfiction could be about the Metal Bat facing an extremely powerful and unknown monster in the One Punch Man universe. He could struggle in the fight at first, using his bat with all his might. But as the battle progresses, he discovers a new level of strength within himself, inspired by the other heroes he has seen in action.
Another common portrayal is his relationship with other heroes being explored more deeply. For example, his interactions with Saitama. Some fanfictions might create a friendship or a rivalry between them that adds new dimensions to both characters. And his role within the Hero Association can also be re - imagined, like being in charge of a special task force.
Sure. In OPM fanfiction, a Metal Bat Dragon OC could be really cool. For example, it could have the strength of Metal Bat combined with the mystery and power of a dragon. Maybe it has a special attack where it can use its bat - like wings to create powerful gusts of wind while breathing fire at the same time. Writers often come up with such interesting concepts to make their stories stand out.
One interesting Metal Bat OC one - shot could be about the OC joining Metal Bat in a battle against a powerful new villain. The OC might have unique powers that complement Metal Bat's brute strength.
The theme of redemption can also be found in some Metal Bat OC OPM one - shots. Maybe the OC has a troubled past or has made mistakes. Meeting Metal Bat and being part of the OPM world gives them a chance to redeem themselves. They might fight against their own inner demons while also fighting external threats alongside Metal Bat. It adds depth to the characters and makes for a more complex and engaging story.
How about a plot twist where Garou suddenly loses his powers. Metal Bat, who has always seen Garou as a powerful adversary, now has to protect him. This forces them to work together in a new way and also makes Metal Bat re - evaluate his perception of Garou.
The plot could be Metal Bat going on a quest to find a special metal to upgrade his bat. Along the way, he encounters various monsters and other heroes. He might have to compete with other heroes who also want the special metal for their own reasons.
