Like the Rake, Maenads embody brutality, animosity, cruelty, and cunning; they are capable hunters and killers, and most do not have a capacity for remorse. Some appear to be ordinary people who were driven to madness by the Rake, while others are deranged serial killers who mutilate themselves in order to imitate their master. Most Maenads have bloodshot eyes and do not seem to require sleep to function; all of them are mentally unstable to varying degrees.
Not all Maenads appear to be insane however; both Spike and Scarneck from Hidden in the Trees did the bidding of the Rake, though they may have been unaware of it.
In some interpretations, Maenads are animalistic shapeshifters that are capable of altering themselves into more sinister and bestial forms.
