The Brothers of the Red is a now-extinct Loyalist Space Marine Chapter and a Successor Chapter of the Blood Angels, created during an unknown Founding. Almost nothing is known about this Chapter in Imperial records. Created as they were from the Blood Angels' gene-seed, they too, carried the genetic flaws inherited from Sanguinius. Like many of their contemporary Successor Chapters founded in later centuries, the Brothers of the Red were greatly affected by the genetic flaw of their Blood Angels' heritage, the Black Rage, which eventually led to their Chapter being fatally undone and their inevitable extinction.
