|Base:||Desert Slave Camp|
|Voiced by:||George Murdock|
Boss Biggis was an obese enslaver in the desert outside Gotham City.
Biggis enslaved many of Gotham City's homeless and put them to work in his slave camp. His scheme was having them dig up gold ore for his own profit. His men eventually brought back a newcomer (Bruce Wayne in disguise). The memory-lost Bruce turned out to be a bother to Biggis when he attempted to execute a camp friend of his. Bruce soon escaped and Biggis' men went after him. As he sat in his cottage eating endlessly, he was encountered by Batman, who had finally remembered who he was. Biggis opened fire on Batman and he chased him into his mines along with his men.
While in the mines, he turned off the lights in an attempt to blind Batman. The plan failed and ended up being a liability, for Batman had the advantage of blending into the darkness. With his men defeated, Biggis tripped and his lantern caught several crates of dynamite on fire. Batman rescued him and they slid down a water pipe into the nearby lake. Biggis was then arrested.
