Ren is the leader of the Knights of Ren before Ben Solo, created by Charles Soule and Will Sliney for Marvel's Star Wars: The Rise of Kylo Ren (2019–2020). The comic establishes that "Ren" is not a surname but a title carried with a specific weapon, passed to whoever takes it from the previous holder.
The band under him is a small, unaffiliated crew of dark side raiders — not Sith, not First Order, and not interested in either — with six members named in the material: Vicrul, Cardo, Ushar, Trudgen, Kuruk and Ap'lek. Ben Solo kills Ren and takes the name, which is the moment the comic exists to depict. Canon.
