At the moment, there are 25 instructors peppered in "Dragon Ball Xenoverse 2" including Goku, Vegeta, Frieza, Broly, Beerus, and Videl, among others.

On a side note, more will be added in the game namely Bardock, Future Gohan, Whis, Cooler, and Android 16 via the upcoming "Dragon Ball Xenoverse 2" free downloadable content (DLC).
