Regi Blattaria

Regi Blattaria is a hostile NPC in the Commonwealth in Fallout 4.

Interactions with the player character
He is hostile.

Trivia
His roach army, and the fact that his name roughly translates to King Roach (Regi from Regis, while Blattaria is the latin name for cockroach) and his carrying a minigun all imply he is a reference to The Roach King from Fallout 3. There is even a toy rocket reminicient of The Roach King's throne on a shelf near where his spawn point.
