Well, a plot could involve Ginga getting a premonition about Madoka's world being in danger. He then goes there to find out that the despair in that world is causing a negative impact on his own world too. So, he teams up with Madoka and her friends to find a way to stop the source of the despair, which might be an ancient evil that has been awakened. This would involve a lot of exploration, character development as they learn from each other's strengths and weaknesses, and some epic battles against the forces of evil.
Well, perhaps a plot where they are transported back in time to an era when magic was first discovered. They have to learn how magic was initially harnessed and face challenges from the past. They could also find out secrets about their own families or the origin of their magic. This would involve a lot of exploration and discovery for both of them, and they would need to support each other through it all.
Well, it could be about their adventures together. Maybe they team up to face a powerful new blader. They might travel to different places in search of rare parts for their beyblades. And along the way, they could encounter various challenges that test their friendship and their skills as bladers.
Ginga's physical abilities like speed and strength could be combined with Madoka's magical powers. For example, Madoka could use her magic to enhance Ginga's attacks, making them more powerful and far - reaching.
Another plot could involve Homura traveling to the Miraculous Ladybug universe. She could initially be suspicious of the heroes there because of her experiences in her own world. However, as she sees how Ladybug and Chat Noir operate and their pure intentions, she decides to help them against a common enemy that is threatening both universes. This would create an interesting dynamic as Homura's more cynical and strategic approach clashes and then blends with the more light - hearted and hopeful nature of the Miraculous heroes.
One plot idea could be that the male OC is a transfer student who has a hidden past as a magical boy from another city. He has different rules about magic compared to the girls in Madoka's town. Another idea is that he is on a mission to break the cycle of the magical girl system from the inside. He tries to convince the girls to stop making contracts without sacrificing themselves.
One interesting plot twist could be that one of them is secretly working for an enemy all along. For example, Sayaka might be unknowingly influenced by a new witch to turn against Kyoko. Another is that they discover a hidden power within their bond that changes the whole dynamic of the story. Maybe it's a power that can rewrite the rules of the Madoka Magica world.
It could be a very supportive relationship. Ginga would be the one out on the battlefield, and Madoka would be his behind - the - scenes support. She'd fix his beyblade when it's damaged, and he'd trust her completely with it. They'd also have a friendly banter, with Ginga always eager to show off his new moves to Madoka.
One idea could be a story where Ginga and Kyoya team up for an unexpected tournament. They have to put aside their past rivalries and learn to work together, facing stronger opponents than ever before.
Some Madoka Magica OC fanfictions explore the idea of an OC coming from a different magical realm. This OC could introduce new magical rules and cultures, which would be really fascinating as it would contrast and interact with the known Madoka Magica magic system.
In some fanfictions, Gingka and Madoka might time - travel back to the origins of beyblades. They learn about the history and secrets of beyblades together. This could involve meeting the very first bladers and getting involved in ancient beyblade battles that shape the future of the sport they love so much.
