Well, if it's a crossover with a sci - fi series like 'Star Wars', characters like Luke Skywalker could be great. He could use his lightsaber skills against the monsters. And the droids could help the Monster Buster Club with technical aspects like tracking or analyzing the monsters.
If it's a crossover with a superhero franchise like 'Marvel', Spider - Man would be a fun addition. His agility and web - slinging abilities could help in chasing and trapping the monsters. And Iron Man could provide high - tech gadgets to the Monster Buster Club to upgrade their weaponry.
For a crossover with 'Harry Potter', characters like Hermione would be amazing. She could use her vast knowledge of magic to assist the club. And Harry himself could be a great addition, using his Gryffindor courage to face the monsters head - on.
Another interesting plot could be a crossover with a post - apocalyptic world. The Monster Buster Club members find themselves in a world where the monsters have already taken over. They have to team up with the survivors of that world, share their knowledge of fighting monsters, and find a way to reverse the situation and restore peace.
John McClane from Die Hard would be a great addition. He has a similar tough - guy attitude and is good at handling high - pressure situations in urban environments. Another good character could be Ellen Ripley from Alien. Her experience with alien threats would contrast well with Rambo's combat skills. Also, Indiana Jones would be a perfect fit. His knowledge of archaeology and adventure - seeking nature combined with Rambo's combat expertise could lead to some exciting storylines.
Storm from the X - Men would be a great addition. She has control over the weather, which could create some really interesting scenarios when combined with Wolverine's combat skills. For example, she could create a lightning storm while Wolverine battles enemies in the rain, using the flashes of lightning to his advantage.
In a crossover with Hannah Montana, obviously Miley Stewart as Hannah Montana herself. She could be in Seattle for a secret concert and needs iCarly's help to promote it without revealing her identity. It would be fun to see Sam trying to keep Hannah's secret while also being her usual wild self around her.
In a crossover with the Lord of the Rings, Aragorn could be an interesting choice. He could bring his leadership skills and combat expertise to Los Santos. The GTA 5 characters might initially be skeptical of his noble ways, but they could learn from him. He could also help them fight against a new evil force that has emerged in the city, perhaps an ancient and powerful gang with dark magic - like abilities.
If it was a crossover with The Evil Within, Sebastian Castellanos would be a great character to include. His detective skills and his ability to handle the nightmarish creatures in his own game could be useful in the Outlast 2 world. He could team up with the Outlast 2 character to solve the mysteries behind the horror. Also, Pyramid Head from Silent Hill could be a terrifying addition. His presence alone would heighten the sense of dread in the Outlast 2 crossover story.
Definitely Goku. Their previous encounters in the Dragon Ball series make it a natural choice. Their power levels and different fighting styles would create great tension and action in the story.
Well, if you're doing a crossover with '101 Dalmatians', Cruella de Vil could be an interesting addition. She might see the Aristocats as a new target for her fur coats, creating a whole new conflict for the cats to face. And the Dalmatians could be allies of the Aristocats, helping them outwit Cruella.
A crossover with 'My Hero Academia' would be interesting with Izuku Midoriya. He could be inspired by the host club's ability to make others feel special and try to incorporate some of those skills into his hero work. And the host club members could be in awe of his quirk and his determination to be a hero.
Goku from Dragon Ball is a must - include. He's the iconic Super Saiyan. And then maybe Thor from the Marvel Universe. Their different powers would make for an interesting dynamic. Also, Link from The Legend of Zelda could be a great addition, as he has his own set of unique abilities.
