Mephisto has been revealed as the newest addition to the Nexus. The addition of The Lord of Hatred will be sure to please fans of the Diablo franchise as he originally appeared in Diablo 2 back in 2000.
Mephisto is a ranged assassin who specialises in sustained area damage and evading crowd control.
While no release date was given usually when a hero is revealed like this they are put on the PTR (Public Test Realm, test servers for Blizzard games) within a week or two, then after one week on the PTR they are released onto the public servers. So expect Mephisto to go live to the public within the next few weeks.
