Summer might be jealous at first. She's used to being the only daughter and having a new baby in the family could mean less attention for her. But as she realizes that the baby is going to be part of the family, she could become really protective. She might also start to think about how she can be a cool big sister and teach the baby all sorts of things she's learned from her adventures with Rick and Morty.
Perhaps the pregnancy could lead to a whole new adventure for the family. The baby could have some sort of special ability due to the family's unique circumstances. For example, it could be immune to the effects of some of Rick's wacky inventions. This would then cause the family to have to protect the baby from those who might want to use its power for their own gain.
They could have mixed reactions. Some might laugh out loud at the absurdity of some of the fan - created stories. It's like seeing a different side of their world through the eyes of the fans.
Rick might react with his usual nonchalance at first, but then secretly be worried. He may start to fix Morty up while muttering about how Morty should be more careful. For example, he'd quickly grab some alien - goo - bandages and start patching Morty up while still complaining.
I wouldn't recommend seeking such content as it's likely to be against community standards and potentially illegal.
This kind of manga is typically unauthorized and can involve explicit and potentially offensive content related to the characters. It goes beyond the intended scope of the original Rick and Morty franchise.
Well, in the world of fanfiction, people can take characters in all sorts of directions. But in the context of 'Rick and Morty', the idea of Rick abusing Morty in the fanfiction is a deviation from the show. The show focuses on their interdependent relationship, with Rick being the brilliant but flawed mentor and Morty being the somewhat naive sidekick. Fanfiction writers might create such scenarios to explore the darker side of their relationship, but it's not a part of the main narrative.
It could be some alien she met during one of Rick's adventures. Maybe she got involved with a being from a different dimension who had a human - like form and they had a brief encounter that led to the pregnancy.
There might be a fanfiction where Rick discovers that an old acquaintance is pregnant and he has to deal with the moral and ethical implications of it. Since Rick is often amoral, this could lead to a really interesting story arc as he tries to figure out what to do. For example, he might be tempted to use the pregnancy for some sort of scientific experiment but then has a change of heart.
You can start by looking on fanfiction websites like Archive of Our Own (AO3). It has a large collection of fan - created works, and you might be able to find some Rick and Morty fanfiction related to pregnancy there. Just use the search function and type in relevant keywords like 'Rick and Morty' and 'pregnant'.
One possible plotline could be Summer dealing with the reactions of her family. Rick might be initially dismissive but then secretly help her. Morty could be in shock but try to support his sister. For example, they could go on adventures to find a solution to her pregnancy in different dimensions.
