This is the combined version of the Goku family's signature Kamehameha (Xz) used by Gokan and Goten. It is a large blue beam fired by putting both hands together at your side then fire them together as one beam. This is the version of Kamehameha when the users combine the power of a Kamehameha. It is as strong as the 2 Kamehamehas because of this. It can only be used by someone who are brothers.
