Well, in a fanfiction scenario where the Star Wars Empire invaded Earth, the first thing that would likely occur is a complete shock to the global population. We have no experience with the kind of technology the Empire wields. Their ability to travel through hyperspace and their powerful force - using Sith Lords would make it a very one - sided battle initially. However, humans are known for their adaptability. Scientists might try to reverse - engineer some of the captured Empire technology. There could also be some humans with latent Force - like abilities that emerge during this time of crisis. The political landscape of the world would be turned upside down as countries would have to unite against this common extraterrestrial threat. And who knows, perhaps we'd see some Jedi - like figures rise among us to lead the fight.
In a Star Wars Empire - invades - Earth fanfiction, the outcome could be grim. The Empire's vast military resources are almost unimaginable. They could easily blockade our planet, cutting off any chance of outside help. Earth's infrastructure would be targeted first, major cities reduced to rubble. But, there might be a glimmer of hope. If the Empire underestimated the human spirit, they could face a more difficult fight than expected. Some people might find ways to use Earth's unique environment against the invaders. For example, using our natural terrains to set up ambushes. Also, the Empire's reliance on the Force could be their downfall if Earthlings somehow found a way to disrupt it or counter it.
If the Star Wars Empire invaded Earth, it would be chaos. Their advanced weaponry like blasters and starships would overpower our current defenses. Earth's militaries would struggle to fight against stormtroopers and AT - AT walkers. Maybe some groups would try to form a resistance, just like in the Star Wars movies.
