Kamehameha!

The first step is to cup your hands together at your waist, with your palms open and your fingers extended and slightly cupped. Then, you focus your chi energy into your cupped hands. Once you have done this, you bring your cupped hands up in front of you to your chest, and then thrust them forward toward your target, yelling "Kamehameha!" as you do so.

The energy will flow from your hands and into your target, causing massive damage.
