A character is the representation of a person in a narrative or dramatic work of art (such as a novel, play, or film). Derived from the ancient Greek word kharaktêr (χαρακτήρ) through its Latin transcription character, the earliest use in English, in this sense, dates from the Restoration... the sense of "a part played by an actor" developed. Character, particularly when enacted by an actor in the theatre or cinema, involves "the illusion of being a human person." Since the end of the 18th century, the phrase "in character" has been used to describe an effective impersonation by an actor. Since the 19th century, the art of creating characters, as practised by actors or writers, has been called characterisation. - WikiWell, there are some who say that we identify with characters by sympathising with the situations that they find themselves in. There are others who say that characters can represent people we want to be like, or people we don't want to be like. Many maintain that fictional characters resemble people in the real world.
But I don't know about all of that when you consider the character of Krang, (from the Teenage Mutant Ninja Turtle Universe) a large pink pulsating brain with eyes and tentacles, sitting, manipulating a control board, in a hollow chamber in the chest of what appears to be a mindless human slave. I have never known any pinkly pulsating tentacled brains personally, and I don't think I know anybody who does; I do not particularly sympathise with the plight of pinkly pulsating tentacled brains; and I don't particularly want to be a pinkly pulsating tentacled brain. It seems to me that the theory of character can only take you so far, and doesn't quite manage to encompass creatures like Krang.
I've been thinking about Krang for a while. I don't know why. Possibly he has a natural charisma. Anyway, what actual function did Krang serve in the TMNT cartoon show? As far as I can remember, he didn't actually do anything. Krang just kind of harrangued Shredder to go after the turtles, and that was it. In Turtles Forever - by far the best Turtle movie - his principle function seems to be to stand around and looked scared every time Shredder does something evil. Sure, Krang is evil too, but he's evil in a placid and domesticated way, and you get the sense that he really doesn't care much about taking over the world. He just kind of blobbles around, pulsating pinkly, and occasionally squalling at Shredder to do something for him.
Oh Krang. It's been so long since you left our television screens. Why don't you ever call?
Is it wrong to be talking this way to a pinkly pulsating tentacled brain who is, by the way, evil?
