Definitely Maurecia. She's got such a fun and unpredictable personality that she can bring a lot of energy to a crossover. Todd would also be great as he's often the 'normal' one in the Wayside chaos, so seeing him interact with characters from other worlds could be really interesting. And let's not forget Mrs. Jewls, who could use her wisdom and authority in a crossover situation to keep things in order or add some comical misunderstandings.
Louis, the yard teacher, could be an interesting character to feature. He has his own set of rules and ways of doing things in the Wayside world. In a crossover, he could be confused by the new characters or perhaps teach them some of his unique ways. And then there's Leslie, who could use her vivid imagination to come up with creative solutions when the crossover situation gets tricky. Her out - of - the - box thinking can be a valuable asset in a fanfiction crossover.
The IMC soldiers can also be great for crossovers. They have their own set of skills and motives. In a crossover with a stealth - based game universe, the IMC soldiers' combat tactics and equipment could add an element of intrigue.
Alya is also a great character to feature. Her intelligence and strategic thinking can be useful in different crossover scenarios. If crossed over with a science - fiction world, she could be involved in advanced technological research or battles against alien invaders.
Wonder Woman is an obvious choice as she is from Themyscira. She can be paired with characters from other universes like Superman for a DC crossover. In a crossover with the 'X - Men' universe, she could interact with Storm, two powerful female characters with different abilities. Another popular character would be Hippolyta. She could be involved in a crossover where she has to negotiate with leaders from other fictional kingdoms or planets.
One character that is often used is Cortana from Halo. Her intelligence and relationship with Master Chief can be a great addition to a crossover. In the Starcraft universe, she could interact with the AI units there. Then there's Fenix from Starcraft. His honor - bound nature and combat prowess would be cool to see in the Halo setting. Also, the Flood-infected characters in Halo could be a unique addition to a Starcraft crossover. They could pose a new kind of threat to the Starcraft races, and seeing how the different factions deal with them would be engaging.
Sigmar is a great choice. His heroic and god - like status in Warhammer Fantasy could make for interesting interactions in a crossover. Another is Malekith. His dark and complex nature would add depth to crossovers, especially with darker - themed universes. Then there's Teclis, the high elf mage. His powerful magic could be a key element when crossing over with other magic - heavy worlds.
Rainbow Dash is also popular. Her athleticism and bold personality can create interesting dynamics. In a crossover with the Teen Titans, she could compete with Robin in a series of challenges, or team up with Starfire to take on a common enemy.
Eli Wallace is a great character to feature. His brilliant mind and his journey from a civilian to an important part of the Destiny crew can bring a lot to a crossover. In a crossover with Stargate SG - 1, he could interact with Daniel Jackson, and they could have some really interesting exchanges about ancient knowledge and technology.
Naruto himself is often a popular choice. His energetic and determined personality can bring a lot to the crossover. He could be curious about the Aico world and use his ninja skills to explore it.
Miia is a very popular character to feature. She's the first monster girl introduced in Monster Musume and has a very distinct snake - like appearance and a naive yet endearing personality. Papi, the harpy, is also a great choice. Her carefree and somewhat ditzy nature can add a lot of humor to a crossover story. Another popular one is Centorea, the centaur. Her noble and strong - willed personality can bring an interesting dynamic, especially when paired with characters from other series who may have different values.
Takeda Shingen is a popular character as well. His charisma and military leadership skills could be translated well into various crossovers. In a crossover with a historical - based story from another region, he could show how his leadership compares. And then there's Kasuga, whose healing abilities could be crucial in crossovers where characters get injured often, like in a battle - heavy crossover with a more violent universe.
