Ron's family might be initially shocked. His parents, who know Shego was once a villain, would be worried about Ron's safety. But they could come around if they see how much Shego has changed and how happy Ron is. His friends might also be skeptical at first but gradually accept it.
Bonnie might be shocked. She could react with disbelief at first, thinking it's some sort of joke or a plot by villains. But as she realizes it's real, she might become a bit envious if she had feelings for Ron or simply be very confused about how such an unlikely pair got together.
Kim might be shocked at first. She's used to Ron being her sidekick and Shego being an enemy. But she could come around and be a sort of godmother figure, helping out when needed. Rufus would probably be excited. He'd be like a little furry uncle to the baby, always there to play and keep the baby entertained.
Ron might be shocked at first. But then, being the good - hearted person he is, he would probably offer his help. Bonnie, on the other hand, could be a bit more hesitant. She might be worried about how this would affect her marriage to Ron. However, as time goes on, she would also come around and be supportive.
Ron's friends from school could be divided. Some might ostracize him for getting involved with a known villain like Shego. Others, who are more open - minded, could see the situation as an opportunity for Ron to change Shego for the better. And Shego's villainous acquaintances might try to use the pregnancy to their advantage, either by blackmailing Ron or trying to turn Shego against him.
Tsukune's human family might be initially shocked. But if they see how much he loves Mizore, they could gradually come to accept her. They would have to get used to the idea of having a youkai in the family. As for Mizore's youkai family, they might be more accepting since they understand the youkai world better. However, they could also be protective of Mizore and want to make sure Tsukune is worthy of her.
Ichigo's family on the other hand, would also be surprised. His father might be a bit more open - minded though, given his own strange abilities and knowledge of the spirit world. His sisters would likely be excited about having Byakuya as a brother - in - law, especially if they see how much Ichigo cares about him. Overall, Ichigo's family would probably welcome Byakuya once they get to know him better.
The reaction of their families could be quite diverse. Natsu doesn't really have a traditional family, but his friends in Fairy Tail are like family. They would be excited and probably throw a huge party. Cana's father, Gildarts, has been absent for a while. But when he hears the news, he might feel a mix of emotions. He could be happy that Cana has found love, but also a bit sad that he hasn't been around more. However, overall, the Fairy Tail guild would embrace their union and make them feel special and loved.
Midoriya's family would be ecstatic. His mother would be busy helping with the wedding preparations, giving advice on everything from the dress to the food. Uraraka's family would be equally happy. They would see Midoriya as a kind - hearted and strong young man. Her mother would likely bond with Midoriya's mother over the wedding plans, and the two families would come together to celebrate the union of the two young heroes.
I think Puck's fairy friends would be divided. Some of his more mischievous friends would be all for it, seeing it as a great opportunity to play more pranks on the mortal world through Sabrina. But his more serious fairy relatives might be concerned about the mixing of the mortal and fairy worlds through this marriage.
Ichigo's family might be a bit surprised at first. His father, Isshin, would probably be happy in the end though, seeing his son find love. His sisters might be excited to have Rangiku as part of the family and look forward to all the fun they could have together. As for Rangiku's side, if she has any family in the Soul Society, they might be a bit more hesitant. They might worry about how a relationship with a human like Ichigo could work out in the long run, but eventually come around when they see how much they love each other.
