Matt Wagner has worked on several of my favorite comics, including Grendel, Batman, and Mage. Grendel and Mage are his own created worlds, and he's a talented writer as well, creating complicated, original plot lines and cool, realistic characters. The storyline of Grendel reached through many miniseries and is set over hundreds of years.

His artwork seems very simple and straightforward, but is truly masterful. His page layout is very original as well - I especially liked some of his designs in Batman/Grendel and the Batman story Faces. His painted covers for Kevin Smith's Green Arrow are pretty nifty too.
