Grubber is a supporting villain in The Powerpuff Girls and is a member of the Gangreen Gang. He appears in a short ugly despising look and appears to be suffering from thyroid disease in both of his eyes. He rarely speaks, instead spitting while sticking his tongue out, with two notable exceptions: he can expertly imitate the voices of Ms. Bellum and the Mayor as shown in Telephonies, and he can speak perfectly when standing straight as shown in Schoolhouse Rocked. The latter is shown to be extremely difficult for him and he can't maintain it for more then a couple of minutes. His red-brown raggedy shirt changed to a purple color in the later episodes. In Power Lunch, he was given the power to burp sonically (from drinking root beer). In the episode Slave the Day it is revealed that he always wins at cards with the rest of the gang, and then devouring his winnings. His raspberries and voice are provided by Jeff Glen Bennett who also voices his fellow gang members, Ace and Big Billy. Both in the anime and original versions of himself disguised themselves as Buttercup, the original Grubber in Buttercrush and the anime in Attack of the Gangreen Gang.
He has black messy hair, a reddish-brown (later changed to purple) shirt, brown pants, a pink tongue always sticking out of his mouth, crooked teeth, bulgy eyes, a rope around his waist and green skin like his fellow gang members.
