Sweet Bro and Hella Jeff were entities summoned in Destroy the Godmodder 2: Operator, and the main characters of the eponymous webcomic Sweet Bro and Hella Jeff. These enigmatic .jpeg jokers were originally summoned by Insert Generic Username, coinciding with the transformation of the Battlefield to the SBaHJlefield. They then proceeded to wreak .jpegy havoc, corrupting other entities and obscuring their names. They were killed by the Godmodder just before the Massive Battle of Armies truly started.
Once the Glitch entered GodCraft, one of the challenges was to defend Sweet Bro and Hella Jeff, who eventually defeated the Glitch Crockercorp Fleet and netted the players another Server Chip. They then left to places unknown.
