Lords of Lightning (2008)

From the publisher's website:

Lords of Lightning presents eleven new antagonists for players and gamemasters to use in their M&M System roleplaying game. These include Adam, Agent Zero, Jules Blitzer, Dynamo, The Hoplite, Keno Kuryente, Nemesis Rex, Raiju, Shock-Trooper, Tempest and Tian-Mu.

Inside you will also find a wealth of adventure hooks and story ideas, including innovative new concepts such as the “Origin-In-A-Box” and “Story Point” sidebars that allow a gamemaster to tie a villain’s background directly into the campaign’s history or the origins of one of the player’s heroes.
