CLASS: BIOCONSTRUCT

   This peculiar being requires fresh DNA to replenish its constantly mutating body, which it absorbs through the tips of its fingers and replaces with its own abnormal cellular matter, resulting in a sudden explosion of warts, tumors and random mutations of the victim's flesh. It twitters and chirps happily as it "feeds."

When upset, a tumorman may squeeze one of its swollen cysts until it bursts, splattering an enemy with acidic pus.
