I'd also agree with both above, that's a given that you should keep a degree of truism to the character.
Certainly that was the case with how DCM portrayed Slade in his Tetzuko comic.
On the other hand, you don't want to get overly detailed in the minutia of a technical subject, either - otherwise you'll end up having the eyes of your reader glaze over.
To keep the pace of the story going, a general overview works best. Just enough to make it sound plausiable without becoming boring.
Actually I liked the way DCM portrayed Slade as a disabled man. Of course, he's hardly typical, but then again, we're not all comic-strip bad-guys.
