One idea could be a joint investigation. Maybe a case starts in Hawaii but has ties to the mainland where NCIS operates. Agents from both teams could meet, and there could be some friendly rivalry as they try to solve the case. For example, McGarrett from Hawaii Five - 0 and Gibbs from NCIS might have different approaches to interrogating suspects. McGarrett could be more upfront and aggressive, while Gibbs has his famous gut - feeling - led interrogations. Their teams would also bring different skillsets. The NCIS agents are experts in military - related crimes, and the Hawaii Five - 0 team knows the local scene and has connections there.
For the other characters, Danno from Hawaii Five - 0 is the more by - the - book type, similar to some of the NCIS agents. So, they could bond over their shared love for following the rules. Meanwhile, Abby from NCIS with her unique and bubbly personality could bring some light - heartedness to the Hawaii Five - 0 team. She could befriend the more easy - going members of their team and introduce them to some of her off - beat hobbies, which in turn could create some fun and comical moments in the crossover fanfiction.
Well, the plot could involve the Hawaii Five - 0 team facing a complex case that requires MacGyver's unique skills. Maybe there's a high - tech bomb threat on the islands, and MacGyver's ability to create solutions out of ordinary things comes in handy. The Five - 0 team could be impressed by his unorthodox methods while MacGyver gets to work with their more traditional law enforcement approach. It could also be about a shared enemy who has ties to both Hawaii and the areas MacGyver usually operates in.
One idea could be a crossover with 'Magnum P.I.'. The characters from 'Hawaii Five 0' could team up with Magnum to solve a crime that spans across different parts of Hawaii. Maybe it involves a smuggling ring that has connections to both the military and local crime syndicates.
First, decide which other show or franchise you want to crossover with. Then, research the characters, settings, and storylines of both. For example, if you choose to crossover with 'Jurassic Park' (a wild idea but fun), study how the dinosaurs work in that world and how the 'Hawaii Five 0' team would react to them. Next, come up with a basic plot. It could be something like the 'Hawaii Five 0' team getting called to an island where a new dinosaur - related threat has emerged.
One great 'NCIS LA and NCIS Crossover Fanfiction' is 'The Joint Operation'. It combines the unique characters from both shows really well. The plot usually involves a case that requires the expertise of both teams. It shows how the agents from NCIS and NCIS LA interact, like how Gibbs' no - nonsense approach clashes and also gels with Hetty's more mysterious style of leadership.
I'm not sure if there's a specific fanfic where Catherine is pregnant in 'Hawaii Five - 0'. Fanfics can vary greatly, and it would depend on the creativity of the individual fanfic writer.
Definitely Steve McGarrett from Hawaii Five - 0 and MacGyver. Steve is a no - nonsense, by - the - book kind of leader, while MacGyver is all about thinking outside the box. Their interactions would be really interesting as they might clash at first over their different approaches but then learn to respect each other's skills. Another interesting pair could be Danny Williams and MacGyver. Danny's humor and MacGyver's calm under pressure would make for some great banter.
Another option is to check out Tumblr. There are many fan communities on Tumblr that share and discuss fanfiction. You might find some great Lucy and Kate NCIS Hawaii fanfiction by searching relevant tags or following some NCIS Hawaii fan blogs.
One great fanfiction could be about Lucy and Kate going on an undercover mission together outside of Hawaii. It might explore their relationship dynamics in a high - stress situation.
