An unexpected ally could be Darth Maul. If Ahsoka travels to a time when Maul is on the run or in a situation where their goals align briefly, they could team up. Maul has a lot of knowledge about the Sith and the dark side that could be useful to Ahsoka.
The droids could be her allies. In some time periods, the droids might have unique information or abilities that can help Ahsoka. For instance, in the Clone Wars era, R2 - D2 could assist her with his knowledge of various starships and secret locations.
She could also find an ally in a young, pre - Sith Anakin Skywalker. If she travels back far enough, she could meet Anakin before he fully turns to the dark side. They could form an alliance, and Ahsoka could try to guide him away from the path that leads to Darth Vader.
In a time - travel scenario to the Clone Wars, Anakin could be a natural ally. He and Ahsoka have a strong bond, and he would likely believe her if she told him about time travel. Together, they could face any challenges.
Boruto could be an unexpected ally. Maybe he somehow gets caught up in the time - travel event with Sarada. They have a strong bond in their own time, and that would carry over. They could work together to face the challenges of the different time periods, like when they encounter powerful and dangerous ninjas from the past or future.
Poison Ivy could be her ally during time travel. Since they have a strong bond in their own time, Ivy could follow Harley through time accidentally. And Ivy's connection to nature might be useful in different time periods. For instance, in a pre - industrial Gotham, Ivy could use her powers to communicate with the natural world to find a way to get them back to their own time.
Maybe Rumplestiltskin. Even though they have a complicated history, in a different time period, they might find common ground. He could be interested in her time - traveling abilities and offer his own brand of help in exchange for something from her future knowledge.
His best friend, Boruto, could potentially be an ally. Even if Boruto doesn't physically travel with him, Shikadai could remember Boruto's advice and use it during his adventures. Boruto's positive and adventurous attitude might inspire Shikadai in difficult situations.
Well, if she travels back to the past of the Hidden Leaf Village, Rock Lee could be one of her allies. Since they are from the same village and are comrades, Lee would be likely to support her and help her with any physical challenges they might face. Also, Guy Sensei could be another ally. His experience and unique ninja style could be very useful in different situations.
Luke Skywalker could be an ally. As a powerful Jedi and her uncle, he would have the knowledge and skills to help her navigate the dangers of time travel. He could also offer guidance on how to use the Force in different time periods.
Koriand'r, her mother, could also be an ally. Her alien powers and knowledge of different cultures and technologies across the universe could come in handy. She might be able to use her powers to manipulate energy in ways that help with the time travel process or protect Mar'i in a dangerous time period.
Sakura could be a great companion. Since they are friends and both have medical and combat abilities, they could support each other during the time - travel adventures. Sakura's brute strength combined with Ino's mind - related jutsu would make a formidable team.
Deidara could be an ally. Since they were partners in the Akatsuki, Deidara might follow Sasori through time, especially if he thought there were new art - worthy explosions to be made in different time periods. Also, Konan could be an ally. Her paper - based abilities and calm demeanor would be useful in different time - travel situations. She could help Sasori blend in or gather information.
