Powerhouse is the official mascot of Powerhouse Comic Con. Created by writer Davidson L. Haworth and artist Chris Marrinan, Powerhouse teams up with Colossus Girl to protect fans from fake shows with no guests, no activities and no fun, as well as from the greed of the corporate shows interested in your pocket not you having a good time. Powerhouse stands for all people and always defends justice in the world and beyond.
