Below is a listing of the Heroes in Clicker Heroes, and their respective abilities / skills. For a more complete walkthrough of Clicker Heroes, please check out this article. Eventually I will expand this walkthrough to include Achievements and Ancients as well.

Please note that the DPS added per new hero level varies depending on a variety of variables, and increase as you gain more levels. Consequently, the numbers below are NOT accurate. The important thing you need to take away from this list is the simple fact that that each hero will add more to your overall DPS than the previous hero... unless, of course, you upgrade the previous hero a lot. Your focus should be on unlocking new heroes rather than putting your all into existing heroes. They all contribute in the end.
