Jacobs the Gigantic is a Unique Dark Berserker found in the Ruined Cistern in  of Diablo III. It always spawns together with Bradshaw the Behemoth and Manning the Monstrous.

In combat, he has the Knockback affix.

Prior to Patch 2.0., they were a group of Champion monsters, but were still named differently each.
