Wolf, from the series, can be a good addition. His tough - guy attitude and skills can either be a hindrance or a help to Alex in a new mission. You could also create a new character, like a young hacker who Alex meets and teams up with. This new character can bring in a fresh perspective and new skills to the story, like being able to hack into the most secure systems to get information for Alex's mission.
I think Ethan Hunt from Mission: Impossible would be a great addition. His high - octane action skills combined with Alex Rider's more stealthy approach would make for an exciting story.
Sabina Pleasure is quite common. Since she has a relationship with Alex, she often plays a role when he's hurt. She might be the one by his side, taking care of him or helping him get back on his feet. Jack Starbright is also very common. She's like a mother figure to Alex, so when he's hurt, she's likely to be deeply involved in his recovery process. And then there's Smithers, who can provide some useful gadgets or help in a more behind - the - scenes way when Alex is injured.
Definitely Medic from Kamen Rider Ex - Aid. Her medical knowledge and combat skills could add an interesting dimension to the story. She could help Kamen Rider Drive when he gets injured during a battle in the crossover scenario.
In my opinion, characters like Iron Man could be great in a Ghost Rider fanfiction. Tony Stark's technology - based approach to problems could contrast well with Ghost Rider's more primal, supernatural powers. Also, Black Widow could add some espionage and stealth elements to the story. Her skills in combat and infiltration could be useful when dealing with the human side of the threats that Ghost Rider might face, while Ghost Rider takes care of the more otherworldly ones.
Takeru Tenkuji (Kamen Rider Ghost) should definitely be included as the main character from his own series. For a crossover with Kamen Rider Decade, Decade would be a great addition. His ability to transform into different Kamen Riders and his experience traveling through different worlds would bring a lot to the story. He could help Ghost navigate through different dimensions or face enemies that are familiar to Decade but new to Ghost.
The main character is Alex Rider, of course. He is a brave and intelligent young spy.
The main character is Alex Rider, of course. He's a young boy who gets involved in spy activities. Then there's Jack Starbright, who takes care of Alex. And there are various spies and villains like Mr. Blunt and Mrs. Jones from the intelligence agency that Alex often has to deal with.
One of the most interesting is Alex Rider for sure. He's brave and resourceful in the face of danger. Sabina Pleasure is also interesting. She's Alex's friend and often gets caught up in his adventures. And there's Wolf, a character Alex meets during one of his missions. He has a tough exterior but a good heart deep down, and his interactions with Alex add a lot of depth to the story.
The main character is Alex Rider. There may also be other supporting characters like his handlers or the villains he has to face. His handlers might be the ones who give him his missions and provide him with the necessary resources. And the villains are the ones creating the problems that Alex has to solve.
There are also his handlers, like Alan Blunt. Blunt is a rather cold and calculating figure who sends Alex on his dangerous missions. His character adds an element of mystery and authority to the stories.
