T'Challa/Black Panther
T'Challa is the benevolent king (and thus Black Panther) of the very advanced nation of Wakanda. At every avenue, T'Challa aims to make peace -- not war. However, he is willing to step up and fight any oppressive/xenophobic/racist forces that may threaten Wakanda -- or even the world. His persona as the king and Black Panther is centered around mysticism, magic, and ultimately, supernatural forces. T'Challa embraces this whole-heartedly. As he says in the comic: "My name is my nature. I can track a body through wind and rain. For I track not the body, but the soul within." Above anything else, T'Challa hates deceivers and does not want to lose his country to evil forces.
Dora Milaje
The Dora Milaje is Wakanda's group of elite female royal guard; they are tasked with aiding the Black Panther in his quest to rid the world of evil and evildoers and protecting Wakanda from her enemies. They are relentless, unforgiving, and ruthless. However, they are exceptionally loyal.
Shuri
Shuri is T'Challa's sister, an heir to the throne, and one of the leading tech experts in Wakanda. When the Black Panther goes out on missions, she takes the throne. She is fierce, incredibly loyal, and tremendously smart.
T'Challa's Father (Presumably T'Chaka)
T'Challa's father was the previous king and Black Panther of Wakanda. He is only briefly mentioned in the comic book, but is portrayed as an unforgiving, mad, and disappointed man who casts out his son, T'Challa and proclaims that he "no longer [his son]."
Doctor Doom
Doctor Doom is only briefly mentioned in the comic book. He is an evil, sinister, scheming villain who attacks Wakanda and destroys a great deal of it.
