Dark Dragon Team (SSJJ)

The Dark Dragon Team is a team of previous villains consisting of Goku Black, Vegeta Black, Vegito Black, and Future Zamasu in order to invade the Demon Realm.

History
Chronoa had Face revive the four villains and request them to invade the Demon Realm and reclaim the sealed heroes. Initially they refuse, but she reveals that if they don't - they'll be erased from history and everything they've accomplish will be undone. They accept her request and set for the Demon Realm through the portal (without realising it is one-way) and begin their battle with the Dark Empire.

Trivia

 * Future Zamasu is the only member on the team who's not currently inhabiting a Saiyan's body.
