Rock Lee: Extra hits
Rock Lee does his extra hits on Gaara, just like in the anime, both when no gates are open and when one gate is open.

Defeating Rock Lee
Use Juraiya. After Rock Lee unlocks both of his gates and attempts to use his special, use Back and A (B + A) to use his needle guardian technique to catch Rock Lee. This uses up Chakra as long as you have the needles out. However, the longer you hold it, the more damage you will do because Lee will be caught in Juraiya's hair. This will require some practice to master, but is a very effective method to finish off Lee, as when he is in his last gate he slowly loses health.
