One possible storyline could be that Starscream's suicidal tendencies stem from his constant failures in his attempts to overthrow Megatron. He might feel so defeated and hopeless that he contemplates ending it all. Another could be that he realizes his actions have led to a great deal of harm within the Decepticon ranks and feels guilty. For example, if his schemes have cost the lives of many Decepticons, he could be overwhelmed with remorse.
The relationship could also be depicted as a cycle of abuse and dependency. Starscream is suicidal because of Megatron's abuse, but at the same time, he has been so long under Megatron's thumb that he doesn't know how to exist without him. Megatron, while not fully understanding Starscream's mental state, still has a hold over him. As the story progresses, they could either break this cycle or be doomed to repeat it.
A theme could be acceptance. They are two very different characters. Megatron is often seen as the powerful, dominant one, while Starscream is more sly and conniving. A kiss between them could represent them accepting each other's flaws and seeing beyond their usual roles.
In a fanfiction, perhaps the sparkling is the result of a long - forgotten experiment by Megatron. Starscream, upon finding out, wants to use this knowledge to blackmail Megatron. However, the sparkling has a mind of its own. It forms an unexpected bond with both Megatron and Starscream. This bond starts to change their relationship as they both start to see things from a different perspective due to the innocent presence of the sparkling.
One great Megatron and Starscream fanfiction could be about their power struggle within the Decepticon ranks. For example, a story where Starscream tries to secretly undermine Megatron's leadership while Megatron is constantly on the lookout for any sign of betrayal. Another could be a more emotional take, perhaps delving into their past relationship before the war, showing a time when they were comrades with different ideals that gradually led to their current tense situation.
First, you need to understand their characters. Megatron is a powerful and ambitious leader, while Starscream is sneaky and power - hungry. You can start with a conflict, like Starscream's latest plot to overthrow Megatron. Then, build the story around how Megatron discovers it or how Starscream tries to cover his tracks.
In fanfiction, the relationship between Starscream and Megatron can be complex. Starscream is often depicted as ambitious and somewhat devious. He has a long - standing relationship with Megatron that is filled with power struggles. Fanfiction writers may explore their dynamic in different ways, such as delving into their past interactions, how they view each other's leadership, or even exploring a more personal or emotional side to their relationship that might not be as obvious in the original source material.
One significance is that it allows for a deeper exploration of character personalities. Starscream's cunning and Megatron's dominance can be examined more closely. For example, a fanfiction might show how Starscream's attempts to overthrow Megatron are not just about power but also about his perception of Megatron's leadership flaws.
One possible storyline could be that Starscream and Bumblebee are forced to team up during a crisis on Cybertron. Maybe there's a new threat that neither of them can handle alone, so they have to put aside their differences. For example, a powerful alien force arrives and starts attacking the Autobots and Decepticons alike. Starscream, being the opportunist he is, realizes that only by working with Bumblebee can he survive and perhaps gain some advantage later. Bumblebee, on the other hand, is hesitant at first but then sees the bigger picture.
Well, there's a fanfiction where Starscream discovers a hidden power and tries to use it against Megatron. It's called 'Starscream's Secret Weapon'. In this story, the author really plays up the tension between the two characters. Also, 'The Rivalry Continues' is a popular one. It's set during the G1 era and shows how their constant power struggle affects the Decepticon cause. They are constantly at each other's throats, but also realize they need each other in a way.
There are fanfictions that depict a more emotional side of their relationship. For instance, Starscream may have hidden feelings for Megatron that he struggles to express because of the strict hierarchy in the Decepticon army. These stories often delve deep into their characters, showing how their personalities interact and how they might overcome the barriers between them.
