MCU Exchange has published a pair of character breakdowns, used in the casting process to give auditioning actors and their agents some insight the roles producers are seeking to fill. The characters, whose names have been changed, are:

[BYRON] 30 – 45, 6’0 or taller, Jamaican, but open to Black Caribbean or African Descent. The smartest man any room, the most effortlessly powerful man in any situation. A natural leader, brimming with resentment, but focused on justice. Physically fit and wildly intelligent. Speaks with a native accent from Jamaica / Caribbean / Africa, etc. SERIES REGULAR

[TAMARA] mid-20’s – early 30’s, African American, female, earthy. A brilliant, confident business owner who prides herself on her independence.. As much as she tries to stay far from trouble, it seems to always find her. ACTORS MUST BE STRONG SINGERS. SERIES REGULAR

It is not yet clear whether these roles are for existing Marvel Universe characters, or whether they're wholly new creations for the Netflix series. However, MCU Exchange speculates that "Byron" could be Bushmaster, another victim of Dr. Bursting, who was responsible for giving Luke Cage his powers.

The site also notes that audition tapes in which actors Evan Parke ("King Kong") and Amina Robinson ("Precious") read for the roles had surfaced online, but have since been removed.

Starring Mike Colter, Mahershala Ali, Simone Missick, Theo Rossi, Erik LaRay Harvey, Rosario Dawson and Alfre Woodard, the 13-episode first season of “Luke Cage” available on Netflix now. The second season is expected to hit the video streaming service in 2018.
