There's often the theme of self - discovery too. Jack, in the presence of these two powerful transformers, learns more about himself. He discovers his courage and loyalty. And for Arcee, her relationship with Jack makes her re - evaluate her own values. As for Airachnid, her presence forces the other two to grow and adapt in different ways.
One common theme is the battle between good and evil, with Arcee and Jack representing the good side and Airachnid as the villain. Another theme is friendship, like the strong bond between Arcee and Jack that is put to the test by Airachnid's actions.
Well, protection is a big theme. Arcee is often portrayed as Jack's protector, and Airachnid is the threat. So, the fanfictions usually revolve around Arcee's efforts to keep Jack safe from Airachnid. Also, the theme of discovery is there, as they try to figure out Airachnid's plans and secrets.
One common theme could be the power dynamic between them. Since Airachnid is a rather menacing character and Jack is a human, exploring how they interact in terms of power is often seen. For example, how Jack might overcome Airachnid's threats.
One common theme could be the 'forbidden love' aspect, as they are from different sides (Airachnid being a Decepticon and Jack being a human). Another might be the idea of redemption for Airachnid through her relationship with Jack.
A great fanfiction I read had Arcee and Jack teaming up to outwit Airachnid. The story starts with Airachnid targeting Jack for some unknown reason. Arcee, being Jack's protector, steps in. The fanfiction then takes us on a journey of how they discover Airachnid's motives and try to stop her. It has some really cool battle scenes and emotional moments between Arcee and Jack.
One common theme could be friendship. Jack and Arcee might form a strong bond in these stories. Another could be growth, as Jack might grow and learn from his experiences with Arcee.
One common theme is probably the overcoming of obstacles. Since they are from different 'worlds' (in the context of the story's universe), there might be things like cultural differences or external threats that they need to deal with before getting married.
The relationship could develop in a very gradual way. Given their initial hostility, it would take time for them to warm up to each other. Maybe Airachnid gets injured and Arcee, against her better judgment, decides to help her. This act of kindness makes Airachnid re - evaluate her view of Arcee. As they continue to cross paths, they start to share their dreams and fears. Airachnid might be afraid of being alone, and Arcee of losing more friends. Through these exchanges, they realize they have a deep connection and their relationship blossoms into love.
One possible theme could be the challenges they face as a couple with an unexpected pregnancy. It might involve how they deal with the reactions of others in their respective worlds.
Another theme is the exploration of an unlikely friendship or more. Given that they are on opposite sides in the original series, fanfiction often delves into how they could bridge that gap. It could involve them having to rely on each other in a dangerous situation in a way that changes their relationship dynamics.
One common theme could be the relationship between Jack and Arcee. It might explore how they interact, support each other, and grow together. Another theme could be about facing challenges, whether it's against their enemies or dealing with personal issues within their relationship. Additionally, themes of discovery, both of themselves and the world around them, could be present in these fanfics.
One possible plot could be that they start as enemies due to their different factions. But as they are forced to work together on a mission, they gradually see the good in each other. Arcee might be initially suspicious of Airachnid's motives, but Airachnid shows a softer side, perhaps saving Arcee from a dangerous situation. This leads to a growing attraction between them and they start to fall in love secretly, hiding their relationship from their respective groups.
