The plot might be centered around a missing scientist. The Hawaii Five - 0 team starts the investigation, but soon realizes that the case involves some sort of high - tech gadgetry and elaborate traps. That's where MacGyver enters. He uses his knowledge of engineering and his knack for getting out of tough situations to help the team. Together, they could travel across different parts of Hawaii, from the beaches to the mountains, following clues and facing off against the bad guys.
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.
A possible plot could be a cyber - attack on Hawaii's infrastructure. The Hawaii Five - 0 team is at a loss as to how to stop it, as it involves very sophisticated technology. MacGyver, who has a lot of experience with makeshift electronics and understanding complex systems, is brought in. He teams up with the Five - 0 members to not only figure out who is behind the attack but also to create a way to stop it. They might have to infiltrate a high - tech lair hidden somewhere in the Hawaiian islands.
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.
It could be a story where the team from Hawaii Five - 0 teams up with the Winchesters. Maybe they are investigating a series of strange murders that seem to have both a supernatural origin and a connection to some powerful Hawaiian mythological entity. The cops' modern investigation techniques could blend with the Winchesters' knowledge of the occult.
One idea could be that the teams are brought together to solve a case involving a military - related crime that has ties to Hawaii. Maybe a stolen military weapon is being sold on the black market there. The characters from Hawaii Five - 0 can provide local knowledge and connections, while the NCIS agents bring their expertise in military investigations. Another idea is that a Navy officer goes missing in Hawaii and both teams have to work together to find him. They might initially have some clashes in their working styles but eventually learn from each other.
One idea could be that a case in Hawaii has connections to a national security threat that NCIS is already investigating. For example, a suspected terrorist cell in Hawaii might be linked to a larger international network that NCIS has been tracking. Agents from both teams could collaborate, with the Hawaii Five 0 team providing local knowledge and the NCIS agents bringing in their expertise on international threats and military - related matters.
A plot could revolve around a character from one show being framed for a crime, and the other team has to step in to prove their innocence. For example, a member of the Five - 0 team is wrongly accused of stealing military secrets, and the NCIS Hawaii team uses their resources to dig deeper and find the real culprit. This could lead to some great character interactions as they learn to work together.
A time - travel crossover fanfiction could be really exciting. Maybe a character from 'Hawaii Five O' travels back in time and has to work with a past version of the team to prevent a major event that would change the future of Hawaii. This would involve a lot of research into the history of the area and could create some really interesting scenarios.
A possible plot is that the father of Catherine's baby is someone unexpected, like a character from her past who suddenly resurfaces. This creates a complex web of relationships and emotions within the Hawaii Five - 0 story. The team has to deal with this new situation while still maintaining law and order in Hawaii.
Perhaps the plot involves a criminal syndicate that mistakes Grace for someone else who has information they want. So they kidnap her thinking she can lead them to something valuable. The Five 0 team then has to figure out the misunderstanding and rescue Grace while also dealing with the syndicate's other illegal activities.
Another plot could be a story of friendship. The female marine is new to Hawaii and feels a bit out of place. She meets someone from the Hawaii Five - 0 team and they initially clash due to their different ways of doing things. But as they work together on a case that involves a missing person with military connections, they learn to respect each other. The female marine uses her unique skills and knowledge of the military world to help in the search, and in the end, they form a strong friendship that endures future challenges.
One idea could be that a case starts in Hawaii and has connections to Los Angeles. The teams from both shows have to collaborate. Maybe a criminal organization is operating in both locations and they are smuggling some high - tech weapons. The characters from Hawaii Five 0 like Steve McGarrett could team up with the NCIS LA agents like G. Callen to take down the bad guys.
