|1st appearance:||The Terrible Secret of Turtle Bay|
|Voice Artist:||Patrick Warburton|
Brock Samson is the one-half Swedish, one-quarter Polish, one-quarter Winnebago murder machine who acts as bodyguard to the Venture Family. He was born in Omaha, Nebraska to a single mother. After being kicked out of college he served in the U.S. Marine Corps before joining the Office of Secret Intelligence, presumably a covert branch of the United States Government. There he acquired secret agent skills and a License to Kill.
It is unclear how he came to be in charge of guarding the Venture clan, but it is possible it was done as a punishment for investigating the 'possible' existence of The Guild of Calamitous Intent shown in the season 3 episode The Invisible Hand of Fate.
The origin of Brock's and Dr. Venture's relationship can be traced back to college, where Brock and Thaddeus were roomates. Not that they ever saw each other. Brock was either too busy playing football or getting laid while 'Rusty' would hang around with his pals playing D&D and doing college work. They never saw each other until the day Brock was expelled for killing a fellow football player. Within ten seconds of meeting, the drunken Samson knocked Rusty's teeth out. The first actual conversation they shared was Brock apologizing for hitting him, then passing along a message that Dr. Venture (Sr.) was dead.
Hank Venture can often be found spending time with Brock, when Brock is not performing maintenance, killing someone, going to strip clubs, or spending time with some lady or ladies. Brock is also a mentor to Dean, however, Dean does not share his brother's total adoration of Brock. Dean generally makes more sense than the excitable Hank and that provides common ground with Brock.
Muscular and exceedingly capable physically, Brock's favorite weapon is his knife. Most encounters between Brock and his adversary end with Brock covered in their blood, standing on a pile of mangled bodies. He's also a red belt in judo (which signifies he is at least an 9th dan), he uses the throw Ogoshi which means major hip throw. 
These people have greatly influenced the way Brock has developed and what he strives to accomplish in life.
Dr. Thaddeus "Rusty" Venture
Brock first met Rusty Venture in college when the two were assigned to be roommates. Their relationship was rocky at first, a classic jock vs. nerd odd couple. Brock was constantly entertaining ladies in the room and this distraction affected Rusty's ability to sleep and therefore study. Sometime after college, Brock now serves as a bodyguard to Dr. Venture and a mentor to his sons, especially Hank. He and Rusty have become relatively good friends, often cracking wise at other people's expense. Dr. Venture is typically very sarcastic towards Brock, constantly referring to himself as Brock's "employer," even though Brock works for O.S.I. They share a typical roommate relationship, often just bantering and doting over trivial, household related issue. They also share a similar mindset to their life as protagonists, finding arching and adventures little more than a nuisance when compared to the excitement of double coupons from the sunday paper. Rusty often ignores Brock's brutally effective body guarding in favor of menial chores. His merciless savagery helps him to dispatch the myriad of monsters, henchmen, and other threats that plague the life of the Venture Family.
Another important character in Brock's life has been Molotov Cocktease. Brock's relationship with Molotov has been an odd one. She killed his partner; in retaliation he killed her father, prompting his dying request that she forever wear a chastity belt. Their next few encounters left him in a burning hotel with stab wounds to both kidneys and Molotov with a missing left eye (which Samson keeps in a jar at his bedside). Even so, Brock is passionately in love with Molotov and is constantly frustrated by her continued use of the chastity belt. Their romantic relationship is finally over when he says that he is tired of chasing after her and that she is a bad person and she tells him that she is spoken for with Monstroso. Their rivalry is finally over when she presumably kills herself and her new boyfriend to piss off Brock and avoid incarceration.
Col. Hunter Gathers
Col. Hunter Gathers was the man who initiated Brock into the OSI. Hunter quickly became a mentor to the younger agent. In Brock's words, Hunter was the "2nd closest thing to a father [he] ever had." However in Assassinanny 911 Brock was forced to hunt down and confront Hunter after he (Hunter) went rogue. Brock was unable to complete this mission because before he could reach Hunter, Hunter had a sex change which made him invulnerable to Brock assassinating him since Hunter always taught him not to kill women or children. Since then he has been informing to Brock (while diguised as a stripper) that the OSI was trying to kill him for not carrying out his orders regarding the Orb. It was, however, all a clever ploy by Molotov Cocktease to get Brock to eliminate her competition. As a result of her plans, Brock left the OSI and joined the new SPHINX operation to hunt down and eliminate mad scientists who aren't Guild-sanctioned..
Even though Brock possesses a license to kill, he refuses to use a gun. He relies instead on brute strength, endurance, and skill with a knife that borders on the supernatural. Men he has served with speak of him as a god, and men have been known to fight over one of his discarded cigarette butts. Brock's killing efficiency is put to the test against The Monarch's horde and other villains. Admiring efficiency and professionalism in others, Brock respects The Guild of Calamitous Intent for the surgical use of their operatives. He remains loyal to the OSI until the Season 3 Finale, before then never wavering on his mission to protect Rusty Venture. His only exception was to never kill female opponents of the Venture clan. He always shows mercy to enemies, respecting the bravery it takes to fight him, and he never makes them feel more pain than needed. He even went so far as singing for man who believed himself to be dying.
Brock Samson was a member of the Office of Secret Intelligence, with a clearance level of 8 (The booklet he found in the gramophone-cylinder box in ORB allowed him level 10 access, but his car attempted to terminate him after he tried to use it. though this was part of Molotov's plan) He carries an O.S.I. issued class "A" license to kill, number 09262-8765-001 (displayed in Mid-Life Chrysalis) and he is an organ donor. He effectively withdrew from OSI when he abandoned Rusty's Blanket, his long term assignment to protect Thaddeus "Rusty" Venture.
After leaving the OSI, Samson found his way to the organization SPHINX. At SPHINX Brock works alongside Hunter Gathers, Shore Leave, Mile High, and other ex-OSI agents.
- Lost his virginity at age 14
- Half Swedish, quarter Polish, quarter Winnebago
- Has a brother
- The cause of death known as Death By Samson (Coined by Henchman 21 in The Lepidopterists to refer to the fate of Henchman 1) is a tribute to his legendary status among members of the OSI, the Guild of Calamitous Intent, and The Fluttering Horde. Ironically the first time it is used he didn't actually kill the person.
- Although he seemed reckless, Brock was law abiding, when his license to kill expired he did not harm anything until he had his renewed.
- it was revealed that Brock babysat General Treister's Son
- In The_Family_That_Slays_Together,_Stays_Together_(Part_1) Brock shaves off his hair to lure Go-Fish to his death and soon after leaves the employ of the Venture family. This is an allusion to the biblical Samson losing his power after cutting his hair.
- It is revealed by GLADOS in Poker Night at the inventory 2 that Brock (and his brother) are the last descendants of Ash Williams and Sheila (of Army of Darkness fame). Well, not last if the number of blond-haired children on the island of Spanikos is any indication.
