Sakura is not to be forgotten. Her medical ninjutsu skills could be used in unique ways in the Aico world. Maybe she could combine her knowledge of herbs with Aico - based medicine to create new healing methods.
Sasuke is also a great character for this. His brooding nature and powerful Sharingan abilities would be interesting in an Aico setting. He might be more suspicious of the new world and its technology, leading to some tense situations.
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.
One interesting concept could be how the unique abilities of characters in Naruto interact with the elements or technology in an Aico - related setting. For example, Naruto's shadow clones might be used in a high - tech mission in the Aico world.
Naruto himself is obviously very popular to feature. His unique personality and powerful ninja abilities make him a great fit in crossovers. Sasuke is also often included. His brooding nature and strong combat skills add an interesting dynamic. Another popular character is Kakashi. His cool demeanor and wide range of skills can create great interactions in crossover stories.
Definitely Naruto and Flash (Barry Allen) themselves. They are the main characters of their respective series, so it's natural that they are at the center of most crossovers. But also, characters like Sasuke from Naruto can be popular. His cool and brooding nature contrasts well with the more upbeat Flash characters. And on The Flash's side, characters like Iris West could also be interesting in the crossover as they could bring a different dynamic to the story.
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.
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.
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.
