One character that would make for an interesting pairing with Doflamingo in a crossover fanfiction is Zoro. Zoro's strong sense of justice and his skills as a swordsman would clash with Doflamingo's devious ways. They could have epic sword battles, and Zoro might be the one to cut through Doflamingo's strings, both literally and metaphorically. Also, Nami could be paired with Doflamingo. Nami's intelligence and ability to manipulate situations for her own gain, although in a more positive way compared to Doflamingo, could lead to some really interesting interactions. She could try to outwit him in a game of wits.
I think Usopp would be an interesting character to pair Doflamingo with. Usopp is known for his lies and trickery, which is somewhat similar to Doflamingo's manipulative nature, but on a much more positive and comical scale. It would be fun to see how Usopp's tall tales and his actual skills would play against Doflamingo's power. Also, Robin could be a great pairing. Robin's knowledge of history and her own mysterious powers could be a threat to Doflamingo's plans. He might try to use her for his own gain, but she would be able to resist him with her intelligence and strength.
Another plot could revolve around an OC who is a former victim of Doflamingo's cruel rule. This OC could be on a quest for revenge. They might start by gathering allies who were also affected by Doflamingo and then plan a elaborate scheme to take him down. Along the way, they could face many challenges and obstacles set by Doflamingo and his loyal followers.
First, consider their backstory. For example, if your OC grew up in a small island that was once under Doflamingo's control but managed to escape, it would shape their personality. They might be cautious, distrustful of authority, and have a strong will to protect others from a similar fate. Their skills could be related to survival, like being an excellent hunter or fisherman, which they learned during their escape.
Well, for a One Piece Doflamingo crossover fanfiction, we could think about a crossover with a fairy - tale world. Picture Doflamingo in a world of Snow White and the Seven Dwarfs. He would be the ultimate villain, trying to take over the magic of the fairy - tale land. He could use his powers to control the dwarfs and try to capture Snow White for his own dark purposes. Another option is a crossover with a superhero world. Doflamingo could be a supervillain who has to face off against a group of superheroes, and his unique powers would make for some very interesting battles.
The power combination. Crocodile's sand - based powers and Doflamingo's string powers can create really cool and unique fight scenes in fanfiction. For example, in some stories, they use their powers together to take on a much stronger foe.
One idea could be that your pet Doflamingo has a unique ability that helps the Straw Hat crew in a strange way. For example, it can sense danger from far away, like when the crew is about to be attacked by the Marines. It might use its flamboyant appearance to distract the enemies while the crew escapes.

Often, these fanfictions highlight their power and influence. Doflamingo's devious nature and Crocodile's calm and calculating demeanor are usually well - portrayed. For example, in some, they might be shown as rivals vying for control in the underworld of the One Piece world.
One possible plot could be that Doflamingo somehow ends up in the RWBY world. He might initially try to take over, using his strings to manipulate the Grimm. But the RWBY team discovers his true nature and battles him. Ruby could use her speed to avoid his string attacks while Weiss uses her glyphs to counter his powers.
