The Monster Association [OPMA] #5279417
Game fan groupsENOne Punch ManPvPGaming Clan
Description
Welcome to the monster association.This is an OPM:A clan focused around monsters, threat levels, and generally pvp. We will focus on being enemies with any Pro-hero association or any other goody heros. I plan to have routine tournaments as well as "grind" sessions to further our strength in the face of our many enemies. Your disaster level will be heavily dependent on your ingame level, with some minor exceptions being how you are actually skilled.
