Frank Horrigan

Frank Horrigan is the Enclave's finest instrument of warfare. Horrigan was born in 2211. Originally a Secret Service Agent for the President of the Enclave, Frank is sent out with several other teams to search for slaves to use for excavating the remains of Mariposa. The year is 2236, somewhere between July and August. Later on in September, scientists unearth the F.E.V. virus and mutations begin to occur amongst those who come in contact with it. Horrigan is one of these unfortunate souls. He is quickly shuttled back to the Enclave for further research.

The timeline is unknown, but between 2236 and 2238 Frank Horrigan undergoes his transformation into a Super Mutant. He is kept under heavy sedation and is operated on by Enclave technicians. In January of 2239, tests are starting to show negative results. It is then decided that Frank should be activated for field operations. Just to clarify...

After a series of sucessful and bloody missions ending in March of 2239, the Enclave creates a modified version of Power Armor specically to encapsulate Horrigan's bulk. Frank Horrigan becomes the end to the Enclave's means. It is to be noted that from this point on, Frank has been "married" to his suit. He cannot be separated from it as it continually pumps him full of drugs, in fact acting as life support.

Horrigan was a mutant, but Horrigan had been a monster before his exposure to FEV in the military base - he had many psychological problems. It's important to note that Horrigan has never considered himself a mutant; only the scientists at the Enclave would consider him one, but they mostly referred to him as an "experiment," and even then, not to his face. Most soldiers considered Horrigan a walking nuke, something the tech boys built, and they were not generally aware of his mutant status. Most did consider him a freak, however, and there were few soldiers who wanted to accompany him on missions.

Horrigan has always been loyal to the Presidency, to the Enclave, and the armed forces - this loyalty was present before his exposure to FEV, and it was reinforced by Presidential Directive through various conditioning and testing programs developed by the Enclave. Horrigan's low Intelligence (which was further damaged by the FEV exposure) made these conditioning programs take root easily.

Horrigan was eventually killed in 2242 by a tribal known as the Chosen One.

Appearances in games
Frank Horrigan is the final boss of Fallout 2, who also appears in a special encounter early in the game killing some defiant peasants and is also seen killing BoS agent Matt in a cut scene in the San Francisco Brotherhood of Steel bunker if the player accesses the ACE computer terminal and clicks on the "What happened to Matt?" option. He was a talking head voiced by Michael Dorn (who also voiced Marcus). He does not appear in any other game.

Behind the scenes
He was named after Clint Eastwood's character in the film In the Line of Fire.
