Fusions.

Fusion Intro . . . .
In the DragonBall world, the ability to fuse is the most powerful thing the warriors can do. Fusion combines the strengths, attacks, and power of the warriors, depending on the fusion technique used.

The first type of fusion that we see in the series is the Namek Fusion. This type of fusion is exclusively for Namek's. First, one Namek places his hand on the other, then ki is concentrated and the fusion begins to take place. The Namek's have the ability to choose which of the two bodies they want to use. The resulting warrior is very powerful, depending on the strength of the two warriors. If by chance the two warriors fusing were once one being and parted for whatever reasons, the Fusion becomes twice as powerful.

The second fusion shown in the series is the Natamoru Fusion, its better known as the Fusion Dance. Goku was taught this technique by two Natamoru Warriors in the afterlife. At first seemed small and weak, but after performing the fusion they turned into a fierce warrior. The fusion technique took Goku a week to learn, because he was unable to practice it with either Natamoru. He teaches it to Goten and Trunks, to fight Buu.
The conditions are that the two warriors must be equally strong and close in size. In order for the fusion to work properly, the second is they must perform a dance perfectly. If any mistake in the dance will end up in a deformed fusion. While performing the dance, the two must yell Fu-Sion-ha. If done properly, this is a very powerful powerup. But it only lasts 30 minutes, and if the warriors are Saiyans and in the Third Super Saiyan level, they can only stay fused for 5 minutes. The fused warrior has a combined attitude from both people, but is a completely different person.

The third and last fusion is the Potara Fusion. The Potara are earings that each Kaioshin wears. When taken off and put on the opposite ears of two people, the Potara pull the people together, creating a new entity. Rou Dai Kaioshin gives his Potara to Goku during the Buu Saga, and Goku fuses with Vegeta, creating the warrior Vegetto. The attitude of the new warrior is a combination of the two. No requirements--other than the Potara be on opposite ears--are required. This fusion is just a jus bit weaker than the Fusion Dance, but it is still a very powerful powerup.
