From publisher blurb:
Fight Nazis and Support a Good Cause
The Brothers of Thunder are a modern neo-Nazi group bringing their particular brand of hatred and fascism to America through any means necessary, aided by the super-powered twins Donner and Blitz and backed up by a legion of Shock Troopers.
This special product for Icons Superpowered Roleplaying is a fundraiser for the Sothern Poverty Law Center, a premier nonprofit legal advocacy and civil rights group that has worked tirelessly against hate-groups for over 45 years. All profits from the sale of this product will be donated to the SPLC.
The Brothers of Thunder includes background on the neo-Nazi organization, Icons stats for their Shock Troopers and two super-powered villains, Donner and Blitz, along with adventure ideas and additional villain concepts for use with the group.
