The Big Boy is a Legendary Fat Man with the Two-Shot prefix, allowing it to shoot two mini nukes at once for the cost of only one, giving it the most damage potential from a single shot in the entire game, with the sole exception of the nuke, which is obtainable only through console commands.
The Big Boy is compatible with the MIRV launcher mod; the Big Boy will shoot an astounding twelve mini nukes, while only consuming one. Be aware that the blast radius of this weapon's mini nukes is substantially larger than normal and that the nukes lose their momentum and fall to the ground after splitting. Also, the cost of this weapon is high, at around 14,000+ caps with no charisma and charisma related perks or effects.

The Big Boy with the MIRV mod will shoot 12 mini-nukes due to both of the mini-nukes fired to each split into 6. Do note that if they fly a certain distance they will disperse into ten bomblets. Due to the way that the legendary Two Shot prefix is programmed, the MIRV nukes will have a much larger blast radius and damage, comparable to twelve individual mini nukes.
