the best android fusion would be super android 17 and super android 13 from movie 7.that would be the strongest charachter in the history of dragonball z gt
Some of the androids already can fuse. I count Cell's absorbtion as a type of fusion. Also, Android 13 uses some parts from Androids 14 and 15 to become Super Android 13. And what about the two Android 17's fusing into Super Android 17.
