Cometary Collision( Player's Handbook II, p. 77)
[Fighter Bonus Feat, General]
You are a thunderbolt of destruction on the battlefi eld. By carefully timing your charge, you rush forward and slam into an enemy just as he gathers the speed needed to charge you. You turn your opponent's momentum against him.
You can ready a standard action to use this feat when an opponent charges you or any other target. At any point during your opponent's charge, you can charge him. In place of the normal charge BENEFITS:, you gain +2 on your attack roll and +4 on your damage roll. Your foe loses the |||of charging (but not the penalties) but can still attack you. If the target charged someone else, he can choose to instead attack you. You take the standard -2 penalty to AC for charging. If you cannot move at least 10 feet or cannot charge due to terrain or other factors, you do not gain this feat's benefit. In either case, you use your readied action to move but do not gain an attack.
A fighter can select Cometary Collision as one of his fighter bonus feats.
