Distortion
Consider adding a distortion pedal to your rig if you're interested in some aggressive drive for your tone. Compared to fuzz and overdrive pedals, distortion pedals are the hardest edged and most aggressive branch of the dirt and drive pedal family tree. Classic examples include the Boss DS-1, MXR Distortion + and ProCo Rat, along with countless contemptorary boutique options like ZVEX Box of Rock and Walrus Iron Horse.
