User(s) Future Trunks; Vegeta; Goku

Ascended Saiyan is a sub-form of Super Saiyan. It isn't technically a different transformation itself, as it is achieved by training as a Super Saiyan and just increases muscle mass. Although it increases muscle mass, it doesn't slow the user down. With even more training, the user can reach an even more powerful form.
