Is there any Green Arrow and Black Canary pregnant fanfiction available?

I'm not sure specifically. You could try searching on popular fanfic platforms like Archive of Our Own. They have a large collection of fanfics related to various characters, so there might be some about Green Arrow and Black Canary with a pregnancy storyline.

Another option could be Tumblr. There are often fanfiction recs (recommendations) on Tumblr blogs dedicated to DC Comics or the Green Arrow and Black Canary pairing. You might find links to relevant fanfiction, or even some original short fanfics posted directly on Tumblr.

There's also 'Black Canary and Green Arrow: Partners in Peril'. This fanfiction takes them on an adventure outside of Star City. It has a great plot that includes some classic villains. The way it portrays their teamwork and the growing affection between them is really well - done.

The Green Arrow and Black Canary's romance in fanfiction is often exciting. Fanfic writers can explore their relationship in different ways. Some might focus on their initial attraction, like how their first encounters in the fictional world of the story could be filled with tension and a spark of something more. They could be in the middle of a dangerous mission and realize they have feelings for each other.

It could be about how they deal with the upcoming addition to their family. Maybe Green Arrow is overprotective while Black Canary is trying to keep her independence.

Well, a very popular theme is their partnership. Fanfictions often show how they combine their skills, with Green Arrow's archery and Black Canary's sonic scream, to take on bad guys. Family also comes up sometimes. Maybe Black Canary's family history or Green Arrow's family legacy and how it affects their relationship and actions. And of course, there are the stories that focus on their adventures in different parts of the DC world, like in Gotham or Metropolis.

One of the great Green Arrow and Black Canary stories is 'Green Arrow: The Longbow Hunters'. It delved deep into their relationship and the grittier side of their crime - fighting in Seattle. It was a more mature take on their characters, showing their flaws and determination.

Green Arrow's vows could be something like, 'Black Canary, you are my partner in every fight, my strength when I'm weak. I vow to always aim true, not just with my arrows but in protecting our love. I will stand by you through every trial, as we have through all our battles together.'

One popular trope is the 'partners in crime - fighting' angle. They often team up in the comics, and fanfictions expand on this dynamic. Another is the 'will - they - or - won't - they' romance trope, as their relationship has an on - again - off - again nature in the source material.

You can start by looking on Archive of Our Own (AO3). It has a large collection of fanfictions, and you can easily search for 'Black Canary and Green Arrow' related ones. There are different categories and ratings so you can find what suits you best.
