In this fanfiction scenario, Goku might end up having to fight Broly while being kidnapped. Since Goku is always up for a good fight, he could use this as an opportunity to test his new powers or techniques against Broly. On the other hand, the Z - Fighters back on Earth would be worried sick. Chi - Chi would be fuming and ready to take matters into her own hands if the others don't act fast enough. Krillin and the others would also be strategizing on how to free Goku without getting him hurt.
Well, one possibility is that Goku's friends would immediately start a search and rescue mission. Vegeta, being his rival but also an ally, would probably be at the forefront. He'd be furious that Broly dared to kidnap Goku. They'd likely track Broly's energy signature to wherever he's taken Goku. Another thing could be that Goku, while kidnapped, tries to reason with Broly. Maybe he discovers that Broly has some deeper issues or motives for the kidnapping that could potentially be resolved through conversation.
