The show 'Raising Kanan' is a prequel to 'Power'. It tells the story of Kanan Stark's early life in the 1990s. It shows his upbringing in South Jamaica, Queens, and how he got involved in the drug trade. His mother Raquel is a major influence in his life, trying to protect him while also being involved in some shady activities herself.
Raising Kanan is not a factual account about 50 Cent. It's a creation for entertainment purposes, but it could incorporate certain themes or situations that are relatable in a broader sense.
There could be characters like Hera Syndulla. She is often associated with Kanan and might play an important role in the graphic novel. Maybe Ezra Bridger could also be in it as he has a connection to Kanan in the Star Wars lore.
Whether the Kanan comics are canon is a matter of debate. Some aspects might align perfectly with established lore, but there could be elements that don't quite fit. It's not a straightforward yes or no answer.
