A frequently used plot device is the change in relationships. When Ichigo is sent to another dimension, his relationships with his friends back home are put on hold, and he forms new bonds in the new place. He might meet a mentor - like figure in this dimension who teaches him new combat techniques or ways to control his powers better. Another common one is the culture shock. The new dimension could have a completely different society, values, and ways of living, which Ichigo has to navigate. This can lead to some interesting character development as he learns and grows from these experiences.
Well, sometimes the plot device is about lost memories. Ichigo could lose some of his memories when he enters the other dimension and has to piece them back together as he progresses through the story. It adds an element of mystery. Also, the idea of a power - enhancing item or location in the other dimension is common. He might find a special place that boosts his powers or an item that gives him an edge in combat. And then there's the conflict between dimensions. There could be a force trying to merge the two dimensions in a bad way, and Ichigo has to stop it.
Often, a power - hungry character might betray Issei. In the world of the fanfiction, power is crucial. So, someone who wants more power than Issei may see him as an obstacle. They could betray him by stealing his power - up opportunities or even directly stealing his power if there's some sort of magic or ability transfer in the story. Also, a character with a hidden agenda related to the overarching plot of the fanfiction world, like a secret organization trying to control the balance of power between devils, angels and fallen angels, could use Issei and then betray him when he has served their purpose.
In some fanfictions, the plot device of a time - loop or alternate reality can lead to Sailor Moon getting hurt. In a time - loop scenario, she may keep repeating the same situation where she gets injured until she figures out how to break the loop. In an alternate reality, the rules may be different, and she may not have all her usual powers or allies, making her more likely to get hurt. Another aspect could be the introduction of a new, mysterious character whose actions or powers are not fully understood at first and end up harming Sailor Moon.
One common plot device is the power - transfer. Another character with similar powers might transfer a portion of their power to Ichigo, jump - starting the process of him getting his powers back. It's a simple yet effective way to show his power restoration.
Another plot could be that Ichigo is transported to a dimension that is a post - apocalyptic world. Here, his skills as a fighter would be put to the test. He might find remnants of a once - great civilization that had technology far different from his own, and he has to use both his swordsmanship and his wits to navigate this dangerous new world.
A very popular plot device is the existence of parallel universes within the Batfamily context. Writers often explore what would happen if a key event in the Batfamily's history was different in another dimension. For instance, what if Jason Todd never died in one dimension? This allows for a lot of character exploration and interesting interactions between different versions of the characters. Also, the idea of a 'dimensional rift' that the Batfamily has to close before it causes chaos is quite common.
In this type of fanfiction, a possible plot is that Naruto is sent to a dimension where time moves differently. He might age at a much faster rate, and he has to quickly master the ways of this dimension to find a way to reverse the time effect on him. Another cool plot could be that he lands in a dimension that is a mirror image of his own, but with opposite personalities for everyone. So he has to deal with a Sasuke who is overly friendly and a Kakashi who is always serious, which makes for a really strange and challenging adventure.
Ichigo often develops greater adaptability. He has to quickly adjust to the new environment, rules, and powers in the other dimension. This makes him more flexible in his thinking and combat strategies. For example, if the dimension has a different type of energy, he learns to incorporate it into his attacks.
Often in these fanfictions, a plot device is the existence of an alternate dimension. The Avengers could find a way to access this dimension where things didn't go wrong and bring back the good elements from there to fix their own world. Additionally, a Deus ex Machina - like event, such as a sudden, unexplained cosmic force that restores everything to normal, is sometimes used. However, this can be a less satisfying device as it doesn't really involve the characters' efforts as much. Another plot device is the power of teamwork being magnified to an extreme degree. The Avengers, by working together in a more perfect way than in the original story, are able to fix all the problems.
One common plot device is the 'accidental discovery'. For example, the protagonist might accidentally stumble upon a hidden vampire lair or a secret about a character's past. Another is the 'accidental transformation', like a human accidentally being turned into a vampire or a werewolf in an unexpected way. Also, the 'accidental meeting' of two important characters who were not supposed to cross paths can lead to a whole new set of events in the fanfiction.
One common plot device is the initial abduction scene, often filled with confusion and fear for the human. Another is the exploration of the alien ship, where the human discovers strange technologies and alien cultures. And the idea of communication barriers between the human and the aliens, which they have to overcome, is also very common.
