Gohan And Vegeta Fusion
Fusion ( 合体 , Gattai , lit. "Union") is the process of merging two or more separate beings into one, combining their attributes, from strength and speed to reflexes, intelligence and wisdom. When properly fused, the single being created has an astounding level of power, far beyond what either fusees would have had individually. So far, it has been shown that there are at least six different ways to fuse and there are many types of fusion.
