Claude is a scout for Amazon Modeling Agency. Along with Romonica DeGregory, he manipulates everyone by praising their beauty and chances of being a model, even - especially - if it's a fib to steer them. He could shrug off Jane Lane drawing him as a vulture but not Daria explicitly insulting him.
It's Claude who focuses the most on the girl's hips and breasts when deciding who should be in, and him in the modeling class who decided to have the girls start caressing boy's chests. Eeesh.
Once Kevin was signed to Amazon, Claude became verbally abusive of him.
