At last available for M&M 2nd Edition!
Thirteen Shades of Darkness contains 2nd Edition M&M stats and background information on 13 supernatural supervillains. Each villain is a slightly different "take" on the genre, a particular shade of darkness. Some are traditional super-criminals who happen to derive their powers from magic, while some are much stranger and pursue less familiar goals. Some are lighthearted, some are mind-bogglingly horrible. Some are both! Every conceivable level of power and lethality is represented, from minor annoyances to dark and malignant gods. Each comes with at least two adventure scenarios, for thirty adventures in total.
All the blood-curdling horror you could possibly want, and perhaps just a little bit more!
