When considering a crossover with a My Hero Academia world, Deku would be a great character to incorporate. His growth from a quirkless boy to a powerful hero could inspire the World Trigger characters. And Bakugo's explosive personality and powerful quirk could add a lot of tension and action to the story. Also, All Might could serve as a mentor - like figure to the World Trigger agents in this crossover.
If it's a crossover with a Naruto - like ninja world, Naruto himself would be a great addition. His energy and determination could contrast and complement the World Trigger characters. Also, Sasuke with his powerful ninja skills could add an interesting dynamic. In a crossover with a One Piece world, Luffy would be a fun character to include. His carefree yet strong - willed nature would bring a new flavor to the story.
Well, if we consider other shonen - style series, someone like Naruto from 'Naruto' could be a potential crossover character. His ninja skills and strong will could create some interesting dynamics with the 'world trigger' characters.
Indiana Jones would be an amazing addition. He's used to dealing with ancient and dangerous things. He could be on the island looking for some lost artifact and end up getting involved with the dinosaurs. His skills in combat and problem - solving would be really useful in the dinosaur - filled world.
In a Dorohedoro crossover with 'One Punch Man', Saitama would be an interesting addition. His overpowered nature would contrast with the often - more - gritty and complex power levels in Dorohedoro. Another good character could be Guts from 'Berserk'. His dark and brooding personality would fit well in Dorohedoro's gloomy atmosphere. Also, Edward Elric from 'Fullmetal Alchemist' could bring his knowledge of alchemy and his quest for truth to the Dorohedoro world.
In vegito crossover fanfiction, characters like Jiren would be great. His strength and stoic nature would make for some intense interactions with Vegito. Also, Android 18 could be included.

His evil nature and thirst for power always make for an exciting addition to any Dragon Ball - related story.

For a crossover with a post - apocalyptic world, characters like Mad Max could be involved. He might see the homunculi as either allies or threats in the harsh new world.

The homunculi could be part of the complex digital and physical world that Neo navigates, and he could help them understand the true nature of their existence in this new, high - tech world.
In a springtrap crossover fanfiction, characters like the Purple Guy could be included. Since he has a connection to Springtrap, it would make for an interesting story.
