Gary "The Rat" Andrews is a self-centered, misanthropic defense attorney who awakens one morning to find that he has somehow transformed into a giant bipedal rat. Gary struggles to deal with his transformation and hold on to his status as a high-paid, if mercenary, lawyer. Until Gary figures out why he's like this he has decided to try and function the best he can in a "human" world. Outraged at his new appearance, Truman, a tenant in Gary's expensive apartment building, has hired exterminator Johnny Bugz to get rid of Gary for good.
Grammer said of the character, "Gary the Rat has been compromising every scruple to the point that he compromises his humanity."[5]
