Arya Stark from 'Game of Thrones' could also work. It would be a very different kind of crossover. Arya's skills as an assassin could be compared to Galen Marek's combat abilities. They could find themselves in a situation where they need to rely on each other's skills in a strange new world that combines elements of both their universes.
One idea could be a crossover with the Star Wars universe at a different time period. Galen Marek could interact with new characters or be part of a different Jedi order. For example, he could be sent on a mission to a planet not yet explored in the original storylines.
Darth Vader also makes appearances in many Galen Marek Clone Wars fanfictions. Given his connection to Galen Marek as his former master, it's interesting to see how their relationship is portrayed in fan - created stories. Writers often delve into the power dynamics and the emotional turmoil between them.

They might start off warily. Galen, being used to the ways of the Sith, would be cautious around Ahsoka, a Jedi. Ahsoka, on the other hand, would be on guard but also curious about Galen. Eventually, they could start to exchange combat techniques and stories of their past experiences.
Well, Galen Marek in a Star Wars Rebels fanfic might be a bit of an anachronism at first glance. But if you think about it, the Star Wars universe is vast. He could have been in hiding for years. In the context of Rebels, he could be a force for change. He might be drawn to the Rebellion's cause because of his own experiences with the Empire's cruelty. His presence could also attract unwanted attention from the Empire, leading to some tense moments in the fanfic. For example, the Inquisitors might sense his power and start hunting him, which could then put the Rebels in danger as they try to protect him.

Goku would be an obvious choice. Having father - son adventures in a crossover setting, like in a different universe or a new realm, could be really exciting. They could face challenges that require both their power levels and unique abilities. It would also be a great opportunity to explore their relationship further in a new context.
Luffy from One Piece could also work well. Luffy's carefree and optimistic nature against Gajeel's more serious and gruff personality would create an interesting dynamic. Maybe they're on a quest to find a powerful treasure in a new world created by the crossover.
