I'm sorry, I don't know who the main characters in the 'Blades in Black Novel' are as I haven't read it.
Not having read the 'Blades in Black Novel', it's difficult to determine the main characters precisely. But thinking about the title, it's possible that there is a protagonist who is on a quest related to the black blades. There might also be an antagonist who either wants to steal these blades or stop the protagonist from achieving their goal with the blades. There could also be side characters like a mentor who teaches the protagonist about the blades' power, or a friend who helps in the battles involving the blades.
In 'Blades in the Black Novel', the character who is an outcast from their own people is really interesting. They have to navigate a world that is often hostile to them because of their different beliefs or abilities. Their journey of finding acceptance and carving out a place for themselves is engaging. Also, the antagonist can be very interesting. Their motives and the way they oppose the main characters are complex. They're not just a one - dimensional bad guy but have their own reasons for their actions, which makes for a great character study.
I'm not entirely sure as I haven't read it in full, but they could be hardened criminals.
The main themes in 'Blades in the Black Novel' are struggle and adaptation. Struggle is everywhere, from battles with enemies to the struggle for resources. Adaptation is crucial because the environment in the novel is constantly changing. The characters need to adapt to new technologies, new cultures they encounter, and new threats. Additionally, the theme of community is important. The various groups in the novel form communities that support each other, and these communities have their own dynamics and hierarchies.
The main characters are Blades and Bumblebee, of course. Blades is known for his certain characteristics, and Bumblebee has his own distinct traits as well.

Since I'm not familiar with the 'Black Messiah Novel', it's difficult to name the main characters.

There might also be characters representing different social strata or groups within the story's setting that interact with the main character in various ways.
