The Feral is a type of Delian that has been genetically altered for an obvious increase in strength and endurance in exchange for neglected agility and overall health.

They are extremely prone to all types of diseases because of the gene scramble, so pro-Delian groups like Casso use them quickly (and often effectively) on the battlefield. They serve as "storm troopers" and front-line offense and defense. They often carry under-slung Medium Machine Guns or Rocket Launchers, making them a very formidable opponent.

And obviously they don't fight in their boxer shorts haha
