The Epic Smiting Paladin. A 25th level paladin with two epic feats in Great Smiting and one in Dire Charge. Add Spirited Charge, Power Attack, and Divine Might to the mix and evil dies quickly. Charge in with your greatsword at +45 atk and 4d6+230 damage, followed by three more smites at +38/+33/+28 atk and 2d6+115 damage. Even without the steed you dish some major damage. Of course while fighting non-evil creatures he doesn't shine nearly as much, but thats part of the fun. (Btw my character doesn't use a lance because I personally don't like the look / feel of lances and disdain using them.) I always did enjoy a smiting paladin.
Math
Atk=+23 bab +10 Str +5 magic +10 smite +2 charge -5 power atk= 45
Dmg=(+15 str +5 magic +75 smite+ 10 power atk+ 10 divine might)x 2= 230
With a Lance the damage would be 3d8+345, on a crit 5d8+575 :\
