A fine selection of dubious characters. But think about it, there is no end to the roster of undesirables Tom has skewered in the past. You could conceivably keep adding to the drawing every time Tom mentions someone new, or even go deep into the archives to dig up an old foe. It could become a living art project that never stops expanding.
Harry Knowles looks appropriately creepy. If you made him lose 300lbs, and he'd look like how I imagine Spike to be.
