One interesting plot could be Beast Boy traveling back in time to the era of dinosaurs. He could use his shape - shifting abilities to interact with the prehistoric creatures. Maybe he tries to prevent an extinction - level event that could have a major impact on the present day. Another plot might be him traveling to the future and seeing a world where all the Titans have disbanded and he has to figure out what went wrong and how to fix it. And a third plot could be traveling to a key moment in the history of his own powers, like the origin of his shape - shifting abilities, and changing something that gives him new and different powers when he returns to his own time.
A cool plot for Beast Boy time travel fanfiction is that he travels back to a time when the Titans first formed. He realizes that there was an unseen threat at that time that could have destroyed the team before it even started. He uses his skills and the knowledge of the future to thwart this threat. Or, he could time travel to a time when his friends are in great danger in the past and he has to rescue them without changing too much of the timeline. Also, he might travel to an alternate past where he has different powers and has to learn how to use them to get back to his own timeline.
In a Beast Boy time travel fanfiction, a possible plot is that he travels to a time during an ancient war on his home planet. He discovers secrets about his race that were lost over time. He might find a way to bring back some of that knowledge to help his current situation. Another idea is that he jumps to different points in time randomly due to a malfunction in a time - traveling device. At each stop, he has to solve a problem related to the Titans or his own identity before he can move on to the next time period. And he could also travel to a time where the Titans are facing their toughest enemy yet, but in the past, and he has to figure out how to defeat them there so they won't be a threat in the future.
