One great MHA time travel fanfic is 'Back to the Start'. It has an interesting plot where the main character goes back in time and tries to change certain events in the MHA world. The character development is really well - done in this one.
The Time Stop Watch was a series of watches that had the function of stopping time. Its core technology was time stop technology, which could detect the passage of time on the watch in real time and stop time. When time stopped, people could experience a brand new time and space. The Time Stop watch series included classic series, sports series, and fashion series. Each watch had a unique appearance and function to meet the needs of different groups of people. The Time Stop watch was not only a high-tech product, but also a fashion choice with personality and values. As for the stop-seconds function, it was a watch experience function that could stop the second hand from running and help the wearer adjust the time more accurately. Watches with a stop-second function were usually equipped with a stop-second device, which could provide convenience when precise time adjustment was needed. According to the information provided, there was no mention of a specific watch brand or product.
Another important aspect is the writing style. It should be engaging and easy to follow. A complex time travel plot can quickly become confusing if the writing isn't clear. The author should be able to set the scene well, whether it's the past or the present in the MHA universe. And the fanfic should also have some sort of emotional depth, like the character's feelings about being in a different time and how they deal with the knowledge they have from the future.
Stopping time in a novel can be achieved through a curse or a rare phenomenon. When doing this, think about how it affects the characters' emotions and the story's tension. Make sure it adds depth and excitement rather than causing confusion.
The movie where time stops is often called the Time Stop Effect or Time Tunnel. It is a very imaginative and adventurous movie.
In this movie, the protagonist was usually a time traveler or a scientist who discovered a way to turn back time. However, when this method was used, time would often suddenly stop. The protagonist would find himself trapped in this time tunnel, unable to return to the past or control the passage of time.
In movies, time stop usually brings various challenges and dangers, such as being trapped in a time-stop tunnel, where time stops causing time to pass abnormally fast, or where time stops causing time to stop.
Watch time stop movies are usually movies that are full of imagination and adventure elements. The audience can experience the thrill and challenge of time travel in them.
One idea could be a character going back in time to prevent a major villain's origin. For example, if someone went back to stop All for One from corrupting Tomura Shigaraki as a child. Another plot could involve a hero traveling to the future to see the outcome of their current actions and then coming back to make changes. Maybe a student like Izuku Midoriya goes to a future where the heroes have lost and tries to change the present to avoid that fate.
I think Ozpin might be a possibility. He has a lot of mystery surrounding him and his knowledge of the world of RWBY. If he were to gain the time - stop ability, he could use it to manipulate events on a grand scale, perhaps to try and prevent some of the greater threats to Remnant that he has foreseen.
