Well, I had one that involved the Straw Hats going to the Star Wars universe, so how about one where they meet the crew of the Enterprise? This will be taking place during the Kelvin timeline aka the 2009 Star Trek. Is easier because we can follow to a tease and not to be worried with all the continuity that has come from other installment.

This is after Wano, so Jinbei is already here and its on the start of the 2009 movie. Is most of the crew meeting the Enterprise and helping out on the dynamic of the Starfleet members. Is going to be fun, plus is a story where Luffy and Spock interact. Do you need more?

''Wow you have pointy ears! That's so cool.'' Said Luffy to spock.

''My ears are perfectly normal for the members of the Vulcan race. However, I know that for some individuals it might see weird.'' Said Spock

''You talk so weird. I like it, jon my crew.'' Said Luffy and everyone sighn at him.

''I´m sorry but I can't. I am a member of Starfleet and I do not wish to join a pirate crew.'' Said Spock.

''No! Join us! Please pointy ears.'' Said Luffy.

The Straw Hat captain tantrum was like of a five year old, the rest of the enterprise was astounded by this.

''Wow, I thought you were bad Jim. But him.'' Said Mccoy.

''I might be a little unprofessional, but I am not a snotty brat.'' Said Kirk

''Why does he act like that?" Asked Uhura.

''Because he is a moron.'' Said the Straw hat crew towards the Vulcan.
