Since it's a fanfiction, Darthe Bader could be an entirely new entity. He might be a rogue agent, or someone with a personal vendetta against Padme or those associated with her. He could be a complex character with both good and bad qualities, but his actions of kidnapping Padme clearly put him in the role of an antagonist for the story.
In some fanfictions, Padme's kidnapping by Anakin could be the catalyst for Anakin's full - fledged turn to the dark side.

One idea could be that Ezra is kidnapped by the Inquisitor because he has some unique Jedi knowledge or power. The rest of Ezra's friends then embark on a dangerous rescue mission, facing various traps and Imperial forces along the way.
One possibility could be a time - travel plot. Maybe Padme somehow gets a glimpse into the future and meets Leia.

The plot could start with Padme being sent on a diplomatic mission to the Naruto universe. There, she meets Naruto and they form an unexpected bond. As time passes, she discovers she's pregnant.

Naruto might have to deal with the ninja clans' reactions, while Padme has to consider the political implications in her own galaxy.

One possible plot could be that Sasuke has some misunderstanding. He might think Naruko is in danger from some hidden enemy in the village.
