Who could be the main characters in an 'owen blue pregnant' fanfic?

One possible plot could be that Owen discovers Blue is pregnant. He then takes on the role of a protector, making sure she has a safe and comfortable place to stay. He gathers resources for her and fends off any potential threats in their environment.

As I haven't read the 'Blue Diamond Pregnant Fanfic', I can't say for sure who the main characters are. But it's likely that Blue Diamond is one of the main characters since the title mentions her pregnancy.

The main characters are obviously Owen and Clare. Owen is likely to be portrayed as someone who has to quickly grow up and face the challenges of impending fatherhood. Clare, as the one carrying the baby, will have to deal with physical and emotional changes, as well as the social implications of being a pregnant teen.

Obviously Ladybug would be one of the main characters as she is the one who is pregnant. Cat Noir would also be a main character as he is her partner and would likely be involved in her pregnancy journey, like helping her and being there for her.

Obviously, Hazel and Augustus could be the main characters. Their love story was central in 'The Fault in Our Stars', and a pregnant fanfic could explore their new chapter as a family. They already had a deep connection, and a pregnancy would add a whole new dimension to their relationship.

The main characters could be a young adventurer who stumbles upon the blue dragon and the delphinium. Or perhaps a wizard who has been studying the delphinium's magical properties and then has an encounter with the blue dragon.

Obviously, Prof Oak would be one of the main characters. And perhaps a young trainer who is helping Prof Oak in his research related to the blue 39 thing. It could be a trainer who has a special bond with a certain type of Pokemon that is somehow related to the mystery.

One possible main character could be a vampire hunter who says 'Let me in' as part of a ruse to get close to Owen. This hunter might have a personal vendetta against Owen for some past event, like Owen killing a loved one of the hunter.

Leafpool could be a main supporting character. As Squirrelflight's sister, she could offer her medical knowledge and emotional support during the pregnancy. Bramblestar would also be important. As Squirrelflight's mate, he could be there to protect her and help with preparing for the kits.

Her family members could also be main characters. Her mother or sister, for instance, could be there to offer their wisdom and practical help during the pregnancy. They could be the ones who give her advice on pregnancy - related matters, like what to eat, how to exercise safely, and how to prepare for the baby's arrival.
