This is probably the most gruesome method Absolute Batman, or any iteration of Batman, has ever used to escape captivity. He pulled out several of his teeth, including premolars and incisors, to fashion a makeshift fist weapon against his captors. He then used his own stomach acid, spraying it onto an enemy’s face. Finally, he employed his solid waste and urine to create makeshift bombs to aid in his escape.
