Yes, there might be. The Transformers Prime series has a large fan base, and it's not uncommon for fans to create fanfiction exploring different aspects of the characters. Jack could potentially be depicted as a Primus fan in some of these stories, perhaps exploring his relationship with the religious or spiritual elements within the Transformers lore.
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.
One common theme is the clash of different cultures. The comical and laid - back Red vs Blue crew against the more serious and complex Transformers' world. Another theme could be teamwork, as both sides have to learn to work together in the crossover stories.
The 'ghost primus' might refer to a very specific concept in a certain fictional universe, perhaps related to a powerful entity or a mysterious being. Without more context, it's hard to say exactly. The 'origin story' part could be about how this 'ghost primus' came into existence. It could be a story of creation, a fall from grace, or an evolution over time.
