Marcus

Marcus is the elderly super mutant sheriff of Broken Hills in 2241 and of Jacobstown in 2281. A survivor of the Master's army, his once fervent dedication to the Master's cause has since softened into a more tolerant attitude.

Background
After the Master's defeat, Marcus wandered aimlessly, looking for fellow super mutants. In the year 2185, at high noon, he encountered a Brotherhood of Steel Paladin in power armor named Jacob, who had pledged himself to the extermination of all mutants. They fought for days with guns and fists, but eventually gave up, each unable to get an advantage over the other. The two started traveling together, arguing over the Unity and Brotherhood doctrine and whether or not the Master could truly neurolink his biology into the Cathedral computer network. As they wandered through the wastes, they attracted a following of other refugees from the war, who believed that Marcus's strength and Jacob's power armor gave them the closest thing available to safety. In Fall of the same year, Marcus and Jacob, along with the trail of ghouls, humans, and super mutants, founded the community of Broken Hills.

After the Chosen One helped him to settle some problems in Broken Hills, Marcus joined the Chosen One on his quest to find the Garden of Eden Creation Kit, and eventually to save the people of Arroyo from the Enclave. When the group's task was complete, Marcus followed the example set by the Chosen One and traveled across the great mountains to the east, to search for other refugees from the Master's army. He never found out what happened to that tribal from Arroyo, but he has a feeling that he did good in the end.

Marcus eventually reached the Mojave Wasteland, where he founded a community for super mutants atop Black Mountain. This fell apart when Tabitha, an insane Nightkin, rallied the less intelligent Enclave-created mutants against Marcus and forced him and his supporters out of the area. By 2281, Marcus had found Mount Charleston, where he founded yet another safe haven for mutants, naming it Jacobstown in honor of his old friend. At Jacobstown Marcus helps and protects schizophrenic Nightkin, and hopes to find a cure with the help of former Enclave scientist Doctor Henry. Marcus will also greet the Courier and warn him about the Nightkin within Jacobstown when the Courier enters Jacobstown for the first time.

Quests

 * Find the missing people for Marcus: Marcus has noticed people disappearing from Lost Hills lately. He wants you to find them.

Effects of player actions

 * Marcus can join the Chosen One's party after the mine purifier has been fixed. He is skilled with big guns and large energy weapons. However, sometimes his use of burst weapons are as devastating to the party as to enemies. Also, as all other super mutants he is incapable of wearing armor, which leaves him somewhat vulnerable. Marcus has innate armor statistics that increase as he gains in abilities. At his highest level, he has the equivalent of a suit of combat armor. Also, the ammunition for his big guns can be hard to come by and expensive to purchase (this can be dealt with, by arming Marcus with a Turbo Plasma Rifle which, while still decent in terms of damage, has a much lower maintenance cost).
 * Having Marcus in your party will generally cause you to be denied entry into the inner sections of Vault City (though not the southern courtyard), so you will have to leave him outside and pick him up on the way out. Becoming Captain of the Guard allows you to get Marcus past the guards, but if First Citizen Lynette sees you with him, you will be kicked out of the city for good.
 * Having both Lenny and Marcus in your party will have Marcus occasionally spouting indicates of a relationship between the two, like "Nice to have another evolved human in the group, Lenny", "Hey Lenny! Ever been to Broken Hills?" and "Lenny! Let's get somethin' to drink!"

Other interactions

 * Taking him to Troy in Vault City will get him purged of all the spent rounds, which are then given to you. You get 20 7.62mm, 40 .44 Magnum JHP, 40 .44 magnum FMJ, 50 5mm JHP, 10 .45 caliber, 24 10mm JHP, 50 .223 FMJ, and 20 9mm ball. He has been shot by a lot of people.

Quest

 * Unfriendly Persuasion: Marcus informs the player that there is a band of mercenaries outside of Jacobstown and that their intentions are less than desirable towards the residents of Jacobstown.

Fallout 2

 * While Marcus says that he is no longer sterile, Chris Avellone, who wrote that dialogue, confirmed that Marcus was only joking and that super mutants remain entirely sterile.
 * During combat, if Marcus is hit by an enemy weapon, he may occasionally cry out, "I am NOT a merry Mutant!" This is a reference to Michael Dorn's role as Worf on Star Trek: The Next Generation, specifically the episode "Qpid", in which Worf protested to being given the role of a "merry man" in Q's Robin Hood recreation.
 * Marcus might say when unarmed and attacking: "one fist, two fist, red fist, blue fist". This is a reference to the Dr. Seuss book One Fish, Two Fish, Red Fish, Blue Fish.

Fallout: New Vegas

 * Marcus was written by Jeff Husges, basing on the character dialogue in Fallout 2.

Appearances
Marcus appears as a companion and a talking head in Fallout 2, and in Fallout: New Vegas as a NPC. He is voiced by Michael Dorn in both.

Fallout: New Vegas
"Welcome to Jacobstown, human. You're free to walk around, just don't stare at the Nightkin. They don't like people looking at them." "Was a resort Pre-War. I renamed it to Jacobstown after an old friend. Died a long time ago." "Was part of Super Mutant army, ran a town, walked the wasteland with a tribal. Now I'm here." "Long story, so here's the short version. The Master created the Super Mutants and Nightkin." "The Master thought he could unify everyone. No more differences, no more war. Didn't end well." "Town was Broken Hills. Bunch of Super Mutants, humans, and Ghouls all living together peacefully. Well, most of the time." "We were looking for a GECK to save the village of Arroyo. Eventually, we did. Nuked an oil rig in the process." "We went separate ways after that. I went east into the Rockies, looking for other mutants like myself." "Don't know what happened to my friend. I've got a felling it turned out all right in the end." "Caesar thinks he can change human nature. Most of the Legion is following Caesar, not Caesar's ideals. When he's gone, it'll crumble." "Might not happen overnight. Might take a few decades. But it'll happen. Basic human nature - greed, ambition, jealousy - will see to it."
