Over my time playing I made several different sets of icons for players to use on blogs, fan sites, and even in Corvus' custom icon pack.
While I did make them from scratch, they are all based directly on graphics from the City of Heroes games. They are not for repackaging and redistribution or commercial use.
I originally put them on my LiveJournal, but this seems a good place to store an extra set would probably easier to find here these days.
All the different versions of the icons I made are in this pack and are 100x100px PNGs with transparent backgrounds. You are welcome to do minor alterations for your blog, fansite, forum avatar, etc, and that includes resizing for smaller sizes.
