Vegeta-Sama!

[Memento]

Now just make fusion move with Goku to make Vegitto, this would be epic xD

lol fusion makes gogeta not vegito xP. And as far as I know, potara causes Vegito. And making potara earrings is gonna take a lot of time . One of them can have a special itr kind 8 and the other will have a special bdy and when the itr hits the special bdy, the dvx leads to a special frame with itr kind 3 and cpoint to catch the other one and cause him to disappear and show the fusion dance pics and then transform.

Using the potara earrings makes Goku and Vegeta fuse into vegito. So it IS fusion, just a diffirent form than the fusion dance that causes them them fuse into Gogeta......
