I think Vegito. Typically Vegetto is a merged entity between Vegeta and Goku. In this movie specifically, either they merged the two or tricked you into thinking they did.
Vegetto is used when authors or fans are referring to an amalgamated character created by fusions between Son Goku and Vegeta, and has been canonically made via Potara Earring Fusions in the Dragon Ball Super anime series after Vegito defused due to lack of fusion time remaining. The short Fusion Dance scene at the end of Dragon Ball Z: Budokai 3 was non-canonical filler showing Teen Gohan and Krillin doing a dance before fusing as Gokhan which does not affect Vegetuh’s status as being Vegito.
