Want more options for building your M&M villains? It's in here. Need sample technology, lairs, archetypes and ways to torment your players? It's in here too. There's also a fully fleshed out evil organization built for you to drop into your campaign. I feel like "Better Mousetrap" is an essential resource that goes hand-in-hand with the Gamemaster's Guide by Green Ronin. I almost never pull one off the shelf without the other. It's just that good.
