To be a real policeman
Be big and strong by heck
But let the strength be always found
Just above the neck.

- During her time with The Fantastic Four, She-Hulk investigated a photographer who was taking pics of her sunbathing on the Baxter Building by helicopter. At one point she commented, "Well, I'm a lawyer, which makes me 25% detective." When the sleaze-bag journalist told her that the pictures were being processed and the negatives were in his safe and that if she took the negatives, she'd be in violation of the law, she simply crushed the safe down to where it couldn't be opened by anyone. Unfortunately for the journalist, the lab color-corrected the prints, making it appear that She-Hulk was just an unnamed, tall woman, preserving her privacy, in a certain point of view.

In a way, Danglard is an inversion : although he is a policeman, the vast expanse of knowledge he has accumulated in other fields (especially literature and history) is sometimes essential in solving the cases.
