Frank Horrigan
race: Super Mutant
affiliation: Enclave
role: Secret Service Agent
location: Enclave Oil Rig
appearances: Fallout 2
dialogue file: QCFRANK.MSG
actor: Michael Dorn

Frank Horrigan is the Enclave's finest instrument of warfare and the final boss of Fallout 2. Described as a "genetically engineered cyborg psycho total homicidal maniac", "a supermutant in power armor" and having been witnessed laughing off plasma rifle fire and punching Deathclaws and armored humans in half, he is one of the deadliest entities that has walked the Wasteland.



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. Some time in 2236, around 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 and scientists under Dr. Charles Curling. In January of 2239, tests are starting to show negative results. It is then decided that Frank should be activated for field operations.

After a series of successful and bloody missions ending in March of 2239, the Enclave creates a modified version of Power Armor specifically to encapsulate Horrigan's bulk. Frank Horrigan becomes the means to the Enclave's ends. It is to be noted that from this point on, Frank is "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 he 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, the PC in Fallout 2. The last hit literally tore him in two along the waist although he was able to gather enough strength for some final words: "Duty, Honor, Courage, Semper Fi..". He claimed that he activated the Rig's self-destruct mechanism, even though this doesn't make any sense and is actually a bluff. The reactor meltdown finished off the Oil Rig, removing all traces of Frank Horrigan.


Standing more than 12 feet tall, Horrigan is significantly taller and bulkier than a standard Super Mutant. His FEV mutation was further augmented with controlled injections of an experimental modified version of FEV developed by the Enclave, resulting in Horrigan being a "next-gen" Super Mutant... stronger, faster, tougher, and just plain meaner. Additionally, a special suit of power armor was cybernetically grafted onto his body, transforming him into a walking death machine without peer. Cybernetic elements include bionic eyes, arm control mechanisms and leg rotators.

Although of generally low Intelligence, Horrigan noticeably lacks the simple-minded "moronic" mental deficencies that commonly plague many Super Mutants such as Harry. For example, Horrigan speaks in complete sentences, using normal tonation and vocabulary, and generally lacks any obvious signs of mental deficiency. Probably, Horrigan mimics the speech manner of his Enclave creators and propaganda programs he heard.

Horrigan has 999 hit points, and is equipped with an End Boss Gun (which appears to be some form of Plasma Gatling weapon), as well as an End Boss Knife (a giant, forearm-mounted blade larger than a normal human). He is also very fast, having a very high number of AP (being able to attack several times per round). If his weapons are disabled (either due to running out of ammo, or if his limbs are crippled by repeated aimed shots) Horrigan will attempt to punch and kick his enemies to death. Normally, he continually fires his gun until he runs out of ammo, at which point he "summons" the knife (that is, the knife just appears out of thin air). Additionally, his armor grants him high resistance against small arms, explosions, laser and plasma bolts, but is somewhat vulnerable to electricity. Damage against Horrigan is capped at 192; that is, no individual attack can damage him for more than 192 hp. Others claim that the best method to kill him is repeated aimed shots at the eyes with Gauss weapons (due to increased chance of critical hits). Again, others claim that attacking Horrigan with a melee weapon makes him more likely to pull out the knife straight away.

There are false rumors that the Mutagenic Serum can kill Horrigan instantly. This is untrue, as Horrigan isn't an average Super Mutant.

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. Analogicaly, another scene of Horrigan killing Deathclaws could be seen in Vault 13 after Enclave raids it second time. He was a talking head voiced by Michael Dorn (who also voiced Marcus). He does not appear in any other game.


Through to a editor inventory, you can get the two weapons (End Boss Plasma Gun and End Boss Knife) and the armor (Frank Horrigan Power Armor) of Frank Horrigan.
