What do you get when you put a washed up loser, an awkward teen going through puberty, and an immortal being into a giant robot? MEGAGOGO, THAT'S WHAT! After ten years of peace and quiet, monsters have returned to wreak havoc on the South. Adam, along with a rag-tag team of misfits, must defend the city of Atlanta. But first they'll have to get past... the KKK!
