In the TV show "Grimm," there are several villains that appear throughout the series. Some of the main antagonists include Adalind Schade, Captain Renard, and the Wesen Council, as well as various Wesen creatures that Nick Burkhardt encounters as a Grimm.
If you're talking about the Sisters Grimm series, no, he's not a villain. In the first few books he keeps insisting he is, but he always ends up saving the Grimms' lives (especially Sabrina's!) and eventually falls in love with Sabrina Grimm.
The only info I have on the 8th Sisters Grimm book is that there is supposed to be a new villain, most likely Japhar, the genie on "Aladen" because it shows a big, green, evil looking genie on the front cover of the book. Puck is defiantly going to be in it too!!! :)
