Bilbo's adaptability would also come from his inner strength. The very fact that he's on a mission to destroy the Ring gives him a sense of purpose. He would look at the differences in time periods as just another obstacle in his path. He might start by observing the locals in the new time period, learning their ways slowly. And as he does so, he could gradually find ways to fit in and use the resources and knowledge available to him to continue his journey towards destroying the Ring.
He would also have to adapt to the different social and cultural norms. In a more primitive time, he might need to learn new survival skills. However, his experience from his own time would still be valuable. For instance, his knowledge of different languages could help him communicate with various races, even if their dialects are a bit different in the past. And he could share stories from his own time to gain allies or at least some form of support.
Bilbo might adapt by using his wits. He's always been a clever hobbit. In an earlier time period, he could use his knowledge of future events to his advantage. For example, if he travels to a time before the discovery of certain paths in Middle - earth, he could be the one to find them first, which would help him in his quest to destroy the Ring.
Perhaps when Bilbo travels back in time, he finds that the Ring has an unexpected origin or connection to other powerful artifacts. This could lead to a whole new set of challenges and adventures as he has to deal with these new revelations while still trying to destroy the Ring. For example, he might find that the Ring is part of a set of items that need to be dealt with together in a specific order.
Judy Hopps, being an adaptable bunny, would likely quickly adjust to different time periods. In the past, she might be initially shocked by the more primitive ways but would soon use her problem - solving skills. For example, if she went back to a time before modern technology in Zootopia, she could use her natural instincts and basic tools to get by. Nick Wilde, on the other hand, would probably rely on his charm. In a more old - fashioned Zootopia, he might use his smooth - talking to blend in and find his way around.
For Killer Croc, it would be a bit of a struggle. In a more civilized time period, he'd have to hide his appearance and find ways to stay out of sight. But he might also discover new places to hide, like old sewers or caves. El Diablo could use his powers in a more discreet way in different time periods. He might be seen as a sorcerer or something supernatural, which could work to his advantage or get him into trouble. And Captain Boomerang would likely try to steal valuable items from different time periods to make a profit when he gets back, but he'd also have to deal with the different laws and cultures.
One great Bilbo Baggins time travel fanfiction is 'Bilbo's Unexpected Journeys Through Time'. It has Bilbo traveling to different eras in Middle - earth's history. He meets his ancestors and gets involved in events that shape the future of the Shire. The author does a wonderful job of keeping Bilbo's character true to the original while adding the exciting element of time travel.
There's also 'Fem Bilbo's Time - Twisted Adventure'. In this one, fem Bilbo's time travel takes her not only to different points in Middle - earth's history but also to some alternate versions of events. The story really plays with the concept of how her being female might change things in a male - dominated world like Middle - earth.
One common theme is redemption. For example, if in the original story a character made a mistake, through time travel, they get a chance to correct it. Another theme is the exploration of their relationship. In different time periods, Bilbo and Thorin may develop a deeper understanding of each other.
In the past, their relationship might start with a lot of mistrust. But as they face challenges together during time travel, like dealing with a time - traveling dark wizard, they begin to respect each other's abilities. For example, Ginny's quick thinking and Draco's knowledge of certain spells become assets. This respect slowly turns into a tentative friendship as they rely on each other more.
Bilbo might become more adventurous and less home - bound. His time - traveling experiences could make him bolder. For instance, he might be more willing to take risks in new situations. Aragorn, in contrast, could gain a deeper understanding of the long - term consequences of his actions. He would see how different choices in the past have led to the present situation in Middle - earth.
Frodo could be one. Since he was also closely associated with the ring in the original story, he might play a role in this fanfic, perhaps as a supporter or someone who has doubts about Bilbo's ability to destroy the ring.
One popular theme is changing the past. In many fanfictions, Bilbo tries to alter certain events in Middle - earth's history through time travel. Another theme is exploration. He travels to different times and discovers new places and cultures. For example, he might visit the ancient dwarven kingdoms at their peak.
