Malefactor (Slash Command)
From City of Heroes: Rebirth - Wiki
/malefactor name or /mal name
A COV-themed command, the COH-themed command is /exemplar name or /ex name, though the commands work in both games (i.e. a villain can use /ex name). This chat command is how a lower leveled character can request to be a lackey of a higher-leveled one. A higher-leveled character wishing to take on a lackey needs to use the /lackey name or /lk name command.
