Invincible is recruited by Titan to help him against Machine Head, the top crime boss in the country. Together, they storm his headquarters... And subsequently get their asses handed to them. Luckilly for them, Cecil tipped off the Guardians of the Globe. The Guardians manage to defeat all of Machine Head's mercenaries except for Battle Beast, who puts Black Samson and Bulletproof into intensive care before disappearing into another dimension. Machine Head is caught and all is good in the world... except now with the organized crime world in a power vaccum, someone has already stepped into Machine Head's place as the new crime lord.
Meanwhile, Eve breaks up with William and Amber still thinks Mark is on drugs.
