What could be the plot of a Transformers Prime fanfiction where Jack becomes a Prime?

The Decepticons would obviously be the main antagonists. Megatron would see Jack as a new threat and would try to eliminate him. Starscream might also be jealous of Jack's new status and try to undermine him in any way he can.

One possible plot could be that Diobot is on a mission related to some ancient Cybertronian technology hidden on Earth. Jack accidentally discovers Diobot's presence. At first, there's tension because Jack is unsure if Diobot is a friend or foe. But as they talk, they realize they both have an interest in keeping the technology out of the wrong hands, like the Decepticons.

One possible plot could be that Jack starts to have strange dreams about Primus. These dreams lead him to search for more information about Primus in the Transformers' history. He might then discover some long - lost secrets related to Primus that the Autobots themselves were not aware of, and this knowledge could put him in a dangerous position as there could be Decepticons or other forces that don't want these secrets revealed.

Perhaps he runs to an abandoned military base. In the Transformers Prime world, there could be old military installations that are no longer in use. Jack might see these as a good place to hide, as they may have some remaining defenses and resources that he could use to protect himself while he figures out his next move.

Well, it could be about Jack initially being scared of the Dinobot due to its large and intimidating form. But as the story progresses, he discovers the Dinobot's noble nature. Maybe they team up to fight some common enemy in the Transformers Prime universe.

It could also be that Arcee is injured herself and in a state of confusion and pain. Her sensors might be malfunctioning, and she mistakes Jack for an enemy. Jack, being the brave human he is, tries to help her but she lashes out at him in her disoriented state.

Yes, there are some out there. You can start by looking on fanfiction websites like Archive of Our Own or FanFiction.net. Just search for 'Transformers Prime Jack x Solus Prime' and you'll likely find a variety of stories with different takes on their relationship.

Adventure is a big theme. Since Jack is often thrust into the world of the Transformers in the series, fanfictions tend to continue that trend. He and Solus Prime might go on quests or face threats together. Also, themes of mutual respect and understanding between their two species are quite common as they learn from each other.

The idea of Jack being a Star Killer in Transformers Prime fanfiction is quite an interesting and rather unorthodox one. In the normal context of the series, Jack is just a human ally to the Autobots. But in fanfiction, the sky's the limit. Some fanfic writers might use this concept to introduce a new and exciting conflict. For example, if Jack were a Star Killer, it could create a huge rift between him and the Autobots, who are generally protectors. This could lead to a complex and engaging story full of moral dilemmas and intense battles as the Autobots might have to decide whether to stop Jack or try to redeem him.

Yes, he could be in certain fanfictions. Fanfiction allows for a lot of creative freedom. Maybe the writer wants to show Jack's journey from being a Unicron fan to realizing the true nature of this evil entity. It can be a great way to explore character development. Or perhaps it's part of a more complex plot where Unicron has some sort of allure that Jack initially falls for, but then has to make a choice between his newfound interest and his loyalty to his Autobot friends.
