How can James, Rhodey, Black Panther and the War Dog interact in a fanfiction?

One possible storyline could be that James and Rhodey are on a mission in Wakanda, and they team up with Black Panther. The War Dog could be a key to unlocking an ancient Wakandan mystery. Maybe the War Dog has a special ability that only Black Panther can understand, and together they have to fight off some common enemies who are after Wakanda's resources.

Since Rhodey is a War Dog in this fanfiction, the plot could revolve around his missions. He might be assigned to protect a certain asset, or infiltrate an enemy organization. Along the way, he could face betrayal from within or have to make difficult decisions that would impact not only his own life but also the safety of others in the Marvel world.

One interesting aspect could be Rhodey's character development. Maybe he has to face new challenges as a War Dog that test his loyalty and courage. For example, he might be sent on dangerous missions alone and has to rely on his wits and combat skills to survive.

The characters would likely start off with some level of distrust. Percy, being a demigod, is used to dealing with his own set of rules and powers. The Black Panther, as the protector of Wakanda, is very protective of his kingdom. For example, when Percy first arrives in Wakanda, T'Challa (the Black Panther) might be on guard. But once they realize they are both fighting for good, they could start to exchange fighting techniques. Percy could show how he uses his sword and powers in combat, while T'Challa could teach Percy some of the Wakandan martial arts moves.

Imagine a scenario where the Wakandan warriors visit Hogwarts. They would be very different from the students there. T'Challa would be very diplomatic in his interactions. He would want to understand the rules and hierarchy of Hogwarts. The Hogwarts students would be curious about the Wakandans' way of life. Neville could be especially interested in the Wakandan plants and herbs, thinking they might have some magical properties. And the Wakandans might be invited to participate in a Quidditch match. T'Challa could show off his athleticism, while his warriors would be amazed by the flying brooms.

In the comics, Rhodey is indeed black. This portrayal has been consistent throughout various storylines and editions.

Since it's a war dog fanfiction, Marvel James Rodney is probably a dog with a name that stands out. He could be portrayed in different ways. For example, he might be a new recruit in the military dog unit, learning the ropes and making mistakes at first but then growing into a very reliable war dog. Or he could be an experienced veteran dog that has seen a lot of action and has many tales to tell, and the fanfiction might explore his past experiences as well as his current ones in the military.
