Tony Stark might be a character who is constantly on the run from the Empire or the First Order. He's hunted because his technology is seen as a threat. Along the way, he teams up with various Star Wars characters, sharing his knowledge and learning about the Force. His journey could be about finding a way to use his technology to bring peace to the galaxy, while also respecting the unique aspects of the Star Wars world.
Tony Stark could play the role of a mentor. He could teach the younglings in the Jedi Temple about technology and how to think outside the box. He'd show them how to use their surroundings to build things that can help them in their battles. He could also introduce concepts like artificial intelligence, but in a way that doesn't conflict with the Force - based beliefs of the Star Wars universe.
Goku could be a hero who saves the day. For example, when the Rebels are facing a powerful Sith Lord, Goku shows up and uses his Ultra Instinct to defeat the enemy. His pure - hearted nature would make him a natural ally of the good guys in the Star Wars universe.
It could be really interesting. Maybe Tony Stark would try to build his own lightsaber using his high - tech knowledge. He might be impressed by the Force and try to find a scientific explanation for it. He could also end up in a Star Wars universe and use his Iron Man suit to fight alongside the Jedi or the Rebels.
A singer might have been used to tell stories through song. In the Star Wars universe, there are many tales and legends. A singer could have been a way to pass on these stories, perhaps about the famous smugglers or the dangerous missions in the Outer Rim. For example, in some of the more populated planets like Corellia, a singer could be a part of the local culture, and Han Solo might have encountered them during his early days there. Also, their music could attract different characters, both good and bad, which could lead to new adventures for Han.
It could be a source of new allies. Earth has a large population, and if the people of Earth were to be introduced to the Star Wars universe, some of them might be Force - sensitive or have skills that could be useful. They could join the Rebellion or the Empire, depending on their motives. For example, Earth's military strategies and technologies could be adapted to the Star Wars setting. The use of Earth - based guerilla warfare tactics could give the Rebels an edge in some battles.
Nebula can play the role of a catalyst. Her presence can push Tony to expand his thinking beyond Earth - bound problems. For example, if there's a story about Tony developing new space - friendly technology, Nebula's knowledge of different alien cultures and technology could be the trigger that sets him on that path.
In Star Wars fanfiction, Starkiller could potentially be a rogue agent during the Clone Wars. He might use his unique Force abilities to either interfere with the plans of the Sith or try to find his own path in the chaos of the war. Maybe he teams up with some Jedi who see his potential for good, despite his dark past or training.
Noble Six could be a smuggler. They would use their skills to navigate dangerous routes and outwit the Empire's patrols, much like Han Solo. Their backstory could be that they were once a part of a military unit but turned to smuggling after some events in their past.
Steve Blum might play a rebel spy. He has the acting chops to convey the secrecy and resourcefulness required for such a role. He could be the one sneaking around the Empire, gathering intelligence and helping the rebels in the solo Star Wars story. His voice can add an air of mystery to the character.
The cake could be used as a plot device to bring characters together. Imagine a scenario where different members of the Avengers gather around to have a slice of hummingbird cake. This simple act can lead to conversations, arguments, or revelations among the characters, furthering the plot. It could also be a way to introduce a new character who is an expert baker and makes the cake for Tony and the gang.
He could fit in as an inventor. He'd use his skills to create new weapons or tools for the Star Wars characters. For example, he could make a better targeting system for the X - wings.
