I downloaded this for my children, as we're always on the lookout for colouring pages. Whilst there are a range of free sites which I regularly use, not a lot of them offer PDF and most require a little work to make them usable. This book offers 11 pages of fairly simple, clean images based on a range of 'Hero Kids'. You'll find the fighter, the mage and a host of others ready for use.
This came to my attention when the price was dropped to free, and as such, I see every reason to recommend it.
