Z-Fighters
A Shueisha team.
Z-Fighters's History
The Dragon Team is a group of Earth's mightiest warriors. Formed during Goku and Bulma's search for the Dragon Balls, they have since fought many battles in order to test their skills and reach other goals, and in turn have become the unofficial defenders of Earth.The sub-team of fighters who are a part of the Dragon Team are referred to as the Z-Fighters. Due to them just being a group of martial artists who group up from time to time, they have no official leader or particular positions. Members will act of their own accord at times, though most if not all have some sort of sense of justice (or eventually developed one) and will make drastic decisions to defend their home. Throughout the years, the group consistently bolstered its ranks through the addition of former enemies and new heroes; they've routinely overcame seemingly insurmountable opponents and always emerged victorious against progressively more powerful foes.
During the Tournament of Power, Team Universe 7 was primarily made up of Z-Fighters - with the exception of two members: Android 17 (who later became one) and Frieza.
