Well, Supergirl could be a good character to include. She could offer a different perspective on the whole baby situation, especially if she has some experience with babies in her own world. Lex Luthor could be an antagonist. He might try to steal the baby for his own evil experiments. And the Kents, Clark Kent's adoptive parents, could be involved, giving Superboy some parental guidance.
The Legion of Super - Heroes could be an interesting addition. They could come from the future to help Superboy deal with the baby. Maybe they know something about the baby's origin or powers. Ma and Pa Kent are also great characters to have. Their down - to - earth wisdom could be really helpful for Superboy. And don't forget about Jimmy Olsen. He could be the comical relief while also being a good friend to Superboy during this strange time.
Definitely Superboy himself. He is the central character. Then, Superman could be a great addition. He could act as a mentor to Superboy in dealing with the baby situation. Lois Lane could also be included. She could be the one providing some practical advice on taking care of a baby. And of course, the baby character is essential.
Definitely their fellow superhero friends like Robin. Robin can bring his detective skills to the story, adding a different dimension to the plot. He could help Wonder Girl and Superboy solve a mystery that is related to the villain they are facing.
Raj could be a great addition. He might be the nervous uncle who is always a bit afraid of holding the baby but tries his best. His attempts at babysitting could lead to some really funny situations, like accidentally mixing up the baby's formula with his coffee.
Danny himself is a must - include. His powers and his dual identity would add a lot of interesting elements. Tucker and Sam are also great choices as they could be Danny's support system while dealing with baby - related situations. Jazz could be included as she often has a more mature and understanding perspective. And of course, Danny's parents, who might be clueless about what's really going on with the baby but still add a lot of humor.
Definitely Harry Potter. He was a good friend of Lupin and Tonks, so he could be like an uncle figure to the baby. He could visit often and share his own experiences growing up in the wizarding world, giving the baby some valuable advice.
Obviously Superboy and Batman Beyond (Terry McGinnis) are must - includes. But also, characters like Max Gibson from Batman Beyond can add a lot. She's smart and tech - savvy, which can be useful when dealing with the mix of Kryptonian powers and high - tech in the fanfiction. Another popular one could be Krypto if you want to bring in some of Superboy's more traditional elements.
Bulma should definitely be included. As Vegeta's wife and the mother of his baby boy, she can add a lot of emotional depth to the story. She can be the one who balances out Vegeta's strict training with love and care for their son.
A common theme is the discovery of his powers. Since he's a baby, he's just starting to figure out what he can do. Another theme is protection. People around him are often trying to protect him from those who might want to harm him because of his powers.
Scott would be a great character to include. He's Stiles' best friend and could offer support and advice on raising the baby boy. Lydia would also be good. She's intelligent and could help with any strange or supernatural situations related to the baby. And Derek, with his brooding nature, could provide an interesting dynamic, perhaps as a sort of mentor figure to the baby as he grows up.
Rachel Berry would be an interesting character to include. She might be overly competitive with the baby, thinking that the baby will steal her spotlight in the glee club in the future. Mercedes could also be there, singing lullabies to the baby. And Mr. Schuester's mother could be a great addition. She could come and visit and give Emma some mother - in - law type of advice, which could create some comical or heartwarming scenes.
Snow White and Prince Charming are obvious choices. As her parents, they play a crucial role in Baby Emma's life. Their love for her and their efforts to protect her can be explored in great detail.
