Potara Earings- This fusion is when there are two earings. Some
one puts one of the earings on one of their ears and you put the one you
have on the opposite ear. The two powers don't have to be equal. The
bad thing is if your ear isn't pearsed it's going to hurt. The good thing is
it adds the two powers together but adds even more power than the
fusion.
Gotenks- Gotenks is the Fusion of Goten and Chibi Trunks Fuse. He
is formed to stop the Evil Majin Buu. He is a very strong character, but
he was cocky because he thought he could easily beat Buu. Buu beats
him easily. Gotenks gets a second chance to defeat Buu, but again ge
was cocky and he was absorbed making Buu even stronger.
Gogeta- Gogeta is the Fusion of Goku and Vegeta. Gogeta never
appeared in the DBZ Series. He only appeared in DBZ Movie 12 to
defeat Janenba from taking over hell. The first time they did the Fusion
Vegeta messed up and made a fist. This caused the Fusion to mess up
forming Fat Gogeta. After being kicked around by Janenba for 30
minutes the Fusion quit. After waiting an hour they did the Fusion again
and eaily defeated Janenba.
Vegeto- Vegeto is formed when Goku and Vegeta put the Potara earings on. The earings are made so that the Fusion will last forever. Vegeto is the most powerful fused Saiyan. Vegeto went into the pores of Buu to rescue all their friends that had been absorbed including Fat Buu. When he did this Buu was turned into his regular form, but Vegeto became unfused.
