Harry Slime is the secondary antagonist in the 1993 British animated TV series Avenger Penguins, but is more of an anti-villain.
Slime is the quite soppy and incompetent henchman to Caractacus P. Doom who does little to help his tutor succeed in the domination of Big City and speaks like Peter Lorre. In addition, he is almost always referred to by his last name.
In A Winter's Tale his foolhardiness gets the better of him and he is sacked by Doom and sent out into the cold, where he befriends a fairy.
Harry Slime is voiced by Jimmy Hibbert who also voices other characters.
