1. Kakuzu's revival- When the lightning heart ran into him..you could tell Kakashi and others were shitting bricks ..gives me goosebumps
2. Pains entrance into Konoha- it shows such a lovely day and emphasizes how lovely the people and the village are, then all of a sudden pain massacres the guard emphasizing on the doom to come, all to the ominous tone of Girei
3. Sasori's explanation on how he creates his human puppets, scary as shit while to the to the tune of Hurricane Suite..With Hiruko's voice ..Totally bad ass
Pain's speech on war and Itachi's speech on reality would be in their any other day...although i guess their not as EPic
